The metal shaper man's blog

Ok….
Downloaded and compiled and fresh copy of heekscad.  Time to get that morning cup of coffee.

Last time I did something similar to this I hunted down the extrude icon which is stored as “extrude.png” .    Need to search on “extrude” and eventually choose an appropriate breakpoint for the c::b debugger.

src/HeeksFrame.cpp|742|if(!wxGetApp().CheckForNOrMore(wxGetApp().m_marked_list->list(), 1, SketchType, _(“Pick one or more sketches, to create extruded body from\n( hold down Ctrl key to select more than one solid )”), _(“Extrude”)))return;|
src/HeeksFrame.cpp|1331|AddMenuItem(solids_menu, _(“Extrude a sketch”), ToolImage(_T(“extrude”)), OnExtrudeButton);|
src/HeeksFrame.cpp|1424|AddToolBarTool(m_solidBar, _T(“Extrude”), ToolImage(_T(“extrude”)), _(“Extrude a wire or face”), OnExtrudeButton);|

Alrighty…. It looks like the magic term is OnExtrudeButton

src/HeeksFrame.cpp|740|static void OnExtrudeButton( wxCommandEvent& event )|
src/HeeksFrame.cpp|1332|AddMenuItem(solids_menu, _(“Extrude a sketch”), ToolImage(_T(“extrude”)), OnExtrudeButton);|
src/HeeksFrame.cpp|1425|AddToolBarTool(m_solidBar, _T(“Extrude”), ToolImage(_T(“extrude”)), _(“Extrude a wire or face”), OnExtrudeButton);|

Sooo.. I guess we need to set a breakpoint in here to follow along.

static void OnExtrudeButton( wxCommandEvent& event )
{
if(!wxGetApp().CheckForNOrMore(wxGetApp().m_marked_list->list(), 1, SketchType, _(“Pick one or more sketches, to create extruded body from\n( hold down Ctrl key to select more than one solid )”), _(“Extrude”)))return;
PickCreateExtrusion();
}

A couple of days ago I tried to extrude a circle it didn’t work. I was able to extrude a rectangle…. Lets try a circle first.

If I draw a circle, select it, and click on the extrude I get this message.

Pick one or more sketches, to create extruded body from
( hold down Ctrl key to select more than one solid )

So…. the break point was not stripped out…
Lets try… Selecting two intersecting surfaces and see what happens.
Same message… Hmmm…
Lets throw a rectangle into the mix to see what happens.
Ok…. the rectangle is extruded and nothing happens to the circles…. I suppose we should just mentally file that for now…

{
if(!wxGetApp().CheckForNOrMore(wxGetApp().m_marked_list->list(), 1, SketchType, _(“Pick one or more sketches, to create extruded body from\n( hold down Ctrl key to select more than one solid )”), _(“Extrude”)))return;
PickCreateExtrusion();
}

Well… Ok then PickCreateExtrusion is the path I want to do down but it seems like there is a whole bunch of stuff going on just prior to that, that I should probably understand.  Yikess… is there are bunch of stuff going on here… I’ve been stepping deep into the code, single stepping and exploring.  Eventually I get bored an choose continue. It seems off and on I  get this SIGPIPE broken pipe message from the IDE… I’m not sure is this is a heeks cad,  code::blocks, Linux, or I’m doing something really stupid issue at this point…  Googling seems to get some very non-helpful answers…..  So… for the moment .. Although this sort of explains it.
Well then again this explains it even better http://en.wikipedia.org/wiki/SIGPIPE
And this kind provides some more enligthenment:http://en.wikipedia.org/wiki/Pipeline_(Unix)
Ok.. Then… It seems there might be some timing out issues within the OS… Seems to make sense, since when I surfing and came back to single step through the debugger, I got the broken pipe….
So.. the moral to the story for the moment is to start the debugger after I get the cut of coffee… not before;)..
Heekscad seems to be making heavy use of lists from the standard template library STL.    I’m a little fuzzy on this STL stuff, but I seem to recall it being discussed in the Paul Kunz C++ lecture series… Lets see I believe I had the lecture series bookmark in my favorites…  I’m going to need to over sections 15 and 16 again….  Darn it…. This sight still doesn’t work in linux…. Time publish and see if I can go over to the wife’s windows machine…..
#$% Of course the wife has a brand new computer and doesn’t have the necessary plugin’s installed…..Let me see… I seem to recall there is another version of the lecture with less issues.. back to my notes.  (You’d think I’d have a search feature on my metalshaperman…. who designed this crappy website… )
Oh… this brings back some memories..

[Edit].
Setting a break point on this line for where things get interesting:

HeeksObj* CreateExtrusion(std::list<HeeksObj*> list, double height)

I had downloaded heeksCAD using SVN and had recopied the project to hack it up.
I want to start playaround with rapidSVN a little bit more and see if I can stay in-sync with the changes.
I don’t know if this was the write thing to do.  But I blew away everything in by desktop heekscad including and downloaded.
I copied my project file from what I had hacked up and fired it up.

I got this:

————– Build: Debug in HeeksCAD —————

WARNING: Can’t read file’s timestamp: /home/jonas/Desktop/HeeksCAD/src/glfont.cpp

g++: obj/Debug/src/glfont.o: No such file or directory
Process terminated with status 1 (0 minutes, 1 seconds)

I think something might be missing from the repository… Need to look at this… but quite time in the house is over:(

There is a features request for revolving a sketch into a solid.

I thought I might try googling a little to see what I could come up with.

http://lignumcad.sourceforge.net/doc/en/HTML/SOHTML/TechnicalReference.html

http://www.opencascade.org/org/forum/thread_8675/

Ok…. I think I found the magic term. BRepPrimAPI_MakeRevol

And this looks very very interesting here:
http://www.opencascade.org/org/forum/thread_13617/

This is me just having my version of fun here.
I downloaded a dxf of a bridge, and I thought it be interesting to see if I could figure out what all is going on when the program loads this this up.
There are probably better ways of doing this, but I thought I’d try this for starters.

It seems that the graphics are loaded up on my debug version at /home/jonas/HeeksCAD_Executable_NotTheBestSolution/share/heekscad/bitmaps.
It look like the file icon I was long for “open.png”  Just to make sure I drew a little smilley face it using GIMP and tried running my debug version from C::B.  Yep… Go the correct file..

So… should be able to search for all occurences of open.png (hopefully it will just be just one).
Ok.. Not that’s curious… I got a big nada… Hmm…  tryed a search on “open”.  I think I found it.

src/HeeksFrame.cpp|1403|m_toolBar->AddTool(wxID_OPEN, _T(“Open”), ToolImage(_T(“open”)), _(“Open file”));|

Just out of curiosity, I’m curious what kind of error message, I’ll get rename the file so heekscad can’t find it.”
This error message pops up:
Can’t load image from file ‘/home/jonas/HeeksCAD_Executable_NotTheBestSolution/bin/../share/heekscad/bitmaps/open.png’: file does not exist.

Ok.. I guess I should change it back.
So… There’s an object toolimage
So… Here is why the “open.png” search didn’t work
interface/ToolImage.cpp|16|ToolImage::ToolImage(const wxString& name):wxImage(wxGetApp().GetExeFolder() + _T(“/../share/heekscad/bitmaps/”) + name + _T(“.png”), wxBITMAP_TYPE_PNG)|
Here is the object declaration of Toolimage.

class ToolImage: public wxImage{
public:
#ifdef HEEKSCAD
static float m_button_scale;
static const int full_size;
static const int default_bitmap_size;
#endif

ToolImage(const wxString& name);

static int GetBitmapSize();
#ifdef HEEKSCAD
static void SetBitmapSize(int size);
#endif
};

Ok… So much for ToolImage.
The next thing to search for is the occurrence wxID_OPEN:

src/HeeksFrame.cpp|76|EVT_MENU(wxID_OPEN, CHeeksFrame::OnOpenButton)|
src/HeeksFrame.cpp|179|file_menu->Append( wxID_OPEN, _( “Open” ) );|
src/HeeksFrame.cpp|1403|m_toolBar->AddTool(wxID_OPEN, _T(“Open”), ToolImage(_T(“open”)), _(“Open file”));|

So… I think the next thing I’m looking for is CHeeksFrame::OnOpenButton

src/HeeksFrame.cpp|76|EVT_MENU(wxID_OPEN, CHeeksFrame::OnOpenButton)|
src/HeeksFrame.cpp|753|void CHeeksFrame::OnOpenButton( wxCommandEvent& event )|

Which leads me to this section of code:

void CHeeksFrame::OnOpenButton( wxCommandEvent& event )
{
wxFileDialog dialog(this, _(“Open file”), wxEmptyString, wxEmptyString, wxGetApp().GetKnownFilesWildCardString());
dialog.CentreOnParent();

if (dialog.ShowModal() == wxID_OK)
{
if(wxGetApp().CheckForModifiedDoc())
{
wxGetApp().Reset();
wxGetApp().OpenFile(dialog.GetPath().c_str());
wxGetApp().OnNewOrOpen(true);
wxGetApp().SetLikeNewFile();
}
}
}

Which makes me say heh?  Good place for me to stop and do something like eat… But first mess with the “Open file” text in wxFileDialog dialog(this, _(“Open file”), to see if I’m where I think I am. This sort like common dialog control  in vb but not quite… I need to figure this out to see where this goes next…
A couple things need to be researched:

wxfileDialog and wxGetApp
Googling for wxGetAPP this sort of popped up….
Looks interesting but I need to stay on track: http://www.classes.cs.uchicago.edu/archive/2003/fall/51044-1/sw/wxX11-2.4.2/demos/

Ok…this is off the wxwidgets.org site.

::wxGetApp

wxAppDerivedClass& wxGetApp()

This function doesn’t exist in wxWidgets but it is created by using the IMPLEMENT_APP macro. Thus, before using it anywhere but in the same module where this macro is used, you must make it available using DECLARE_APP.

The advantage of using this function compared to directly using the global wxTheApp pointer is that the latter is of type wxApp * and so wouldn’t allow you to access the functions specific to your application class but not present in wxApp while wxGetApp() returns the object of the right type.

IMPLEMENT_APP(HeeksCADapp) appear in the code.  So it appears that the function definitions are called out in HeekCADapp.  So I have a trail of breadcrumbs to follow.

I wanted to try a little experiment the code.:
//wxGetApp().Reset();
HeeksCADapp().Reset;
wxGetApp().OpenFile(filepath.c_str());
wxGetApp().OnNewOrOpen(true);
wxGetApp().SetLikeNewFile();

So it got this error when I compiled.

/home/jonas/HeeksCAD/src/HeeksFrame.cpp||In member function ‘void CHeeksFrame::OnRecentFile(wxCommandEvent&)’:|
/home/jonas/HeeksCAD/src/HeeksFrame.cpp|1050|error: statement cannot resolve address of overloaded function|
||=== Build finished: 1 errors, 0 warnings ===|

I need to think about this a little. I’m not understanding something. JTTODO I’ll try to pick that up later.
[Edit 6/11]
Ok… This is going to be one long post. Lets see if I pop off a little here before I go to work.
It appear’s that “HeeksCADapp::Reset()” has a bunch of interesting things going on but are what I’m interested in following at the moment:

void HeeksCADapp::Reset(){
m_marked_list->Clear(true);
m_marked_list->Reset();
std::set::iterator It;
for(It = observers.begin(); It != observers.end(); It++){
Observer *ov = *It;
ov->Clear();
}
Clear();
EndHistory();
delete history;
history = new MainHistory;
m_current_coordinate_system = NULL;
m_doing_rollback = false;
gp_Vec vy(0, 1, 0), vz(0, 0, 1);
m_frame->m_graphics->m_view_point.SetView(vy, vz);
m_filepath = wxString(_(“Untitled”)) + _T(“.heeks”);
m_hidden_for_drag.clear();
m_show_grippers_on_drag = true;
*m_ruler = HRuler();
SetInputMode(m_select_mode);

ResetIDs();
}

It think what I’m interested in learning is down this path,”wxGetApp().OnNewOrOpen(true);”
Let’s see what that looks like:
void HeeksCADapp::OnNewOrOpen(bool open)
{
for(std::list::iterator It = m_loaded_libraries.begin(); It != m_loaded_libraries.end(); It++){
wxDynamicLibrary* shared_library = *It;
bool success;
void(*fnOnNewOrOpen)(int) = (void(*)(int))(shared_library->GetSymbol(_T(“OnNewOrOpen”), &success));
if(fnOnNewOrOpen){
(*fnOnNewOrOpen)(open ? 1:0);
}
}
}

Welll…. Ok…. First glance it doesn’t look like we’re doing any dxf”ish. Hmmm devil is in the details.
Wait a second… I think I jumped a little to far ahead… I need to go back to wxGetApp().OpenFile(filepath.c_str());

bool HeeksCADapp::OpenFile(const wxChar *filepath, bool import_not_open, HeeksObj* paste_into)
{
m_in_OpenFile = true;
m_file_open_or_import_type = FileOpenOrImportTypeOther;

// returns true if file open was successful
wxString wf(filepath);
wf.LowerCase();

bool open_failed = false;

if(import_not_open)StartHistory();

if(wf.EndsWith(_T(“.heeks”)) || wf.EndsWith(_T(“.HEEKS”)))
{
m_file_open_or_import_type = FileOpenOrImportTypeHeeks;
OpenXMLFile(filepath, import_not_open, paste_into);
}
else if(wf.EndsWith(_T(“.svg”)) || wf.EndsWith(_T(“.SVG”)))
{
OpenSVGFile(filepath, import_not_open);
}
else if(wf.EndsWith(_T(“.stl”)) || wf.EndsWith(_T(“.STL”)))
{
OpenSTLFile(filepath, import_not_open);
}
else if(wf.EndsWith(_T(“.dxf”)) || wf.EndsWith(_T(“.DXF”)))
{
m_file_open_or_import_type = FileOpenOrImportTypeDxf;
OpenDXFFile(filepath, import_not_open);
}

// check for images
else if(OpenImageFile(filepath, import_not_open))
{
}

// check for solid files
else if(CShape::ImportSolidsFile(filepath, import_not_open))
{
}
else
{
// error
wxString str = wxString(_(“Invalid file type chosen”)) + _T(” “) + _(“expecting”) + _T(” “) + GetKnownFilesCommaSeparatedList();
wxMessageBox(str);
open_failed = true;
}

if(import_not_open)EndHistory();

if(!open_failed)
{
if(!import_not_open)
{
WereAdded(m_objects);
m_filepath.assign(filepath);
InsertRecentFileItem(filepath);
SetFrameTitle();
}
}

m_in_OpenFile = false;

return true;
}

On a side note. I’m just starting to play with code::blocks books marks.
Looking at :

void HeeksCADapp::OpenDXFFile(const wxChar *filepath, bool undoably)
{
HeeksDxfRead dxf_file(filepath);
dxf_file.DoRead(undoably);
}

[edit June 12]
I’m wondering if there is a easier way of doing this.
I guess there is two ways of looking at this. Knowing where you where you started and figure out where your going…. or…. find a particular point in the code and figure out how you got there.

Might as well keep going here:
Searching on “DoRead” I come up with this…
void CDxfRead::DoRead(bool undoably)
{
if(m_fail)return;

get_line();

while(!((*m_ifs).eof()))
{
if(!strcmp(m_str, “0”))
{
get_line();

if(!strcmp(m_str, “LINE”)){
if(!ReadLine(undoably))return;
continue;
}
else if(!strcmp(m_str, “ARC”)){
if(!ReadArc(undoably))return;
continue;
}
else if(!strcmp(m_str, “CIRCLE”)){
if(!ReadCircle(undoably))return;
continue;
}
else if(!strcmp(m_str, “ELLIPSE”)){
if(!ReadEllipse(undoably))return;
continue;
}
else if(!strcmp(m_str, “SPLINE”)){
if(!ReadSpline(undoably))return;
continue;
}
else if(!strcmp(m_str, “LWPOLYLINE”)){
if(!ReadLwPolyLine(undoably))return;
continue;
}
}

get_line();
}
}
I think I jumped a few steps here from  but it appears to be stll heeks software ware we’re in…

I starting to feel more comfortable with the C::B ide. But I still not very versed in C++ debugging techniques. I remember in the Paul Kunz course he mentioned some technique that could track some routines called. It was one of those, “Oh I need to remember that” moments,… I did… just not where and what…Oh well..
Anyway… might have been Dtrace
I’m not sure I’m a level where I need to mess with that..

Well, code::blocks has debugging tools.. I suppose I should rtfm
Bunch of stuff in there I suppose..
[ edit 6/12/09 ] I found something more of interest here.
Quoting verbatim:
Debugger:

* Interfaces GNU GDB
* Also supports MS CDB (not fully featured)
* Full breakpoints support:
o Code breakpoints
o Data breakpoints (read, write and read/write)
o Breakpoint conditions (break only when an expression is true)
o Breakpoint ignore counts (break only after certain number of hits)
* Display local function symbols and arguments
* User-defined watches (support for watching user-defined types through scripting)
* Call stack
* Disassembly
* Custom memory dump
* Switch between threads
* View CPU registers

So lets see what I get with GNU GDB … I just checked synaptic, code is loaded up on my system.

Ok… I seem to have found some code::blocks instructions

This seems like this this my be the topic of another post.

Ok… My main goal in looking at Heekscad is to gain and understand on how opencascade goes from the OCC code to a OpenGl graphics window.  It has been very frustrating to me to see a simple makebottle example OCC provides with no explanation on how to get it drawn on the screen.  Well if there is a explanation  I haven’t run across it.  I guess it might be rudimentary to guys who have degrees in this stuff, but it’s not to me(not yet anyway).  I would like to make a heavily documented how to on how get that darn makebottle working… anyway that’s the goal anyway I guess we’ll see if I get there.  But first we need to just have some fun and poke and prode a little under the hood of heeks cad to figure out how it interacts with opencascade libraries.

The heeksCad source code had be found here.

Heekcad being a Wxwidgets project, doesn’t have a main(not one that you’ll see in your source anyway)   As explained here , the magic terms you need to look for to figure out the starting point are the macro called IMPLEMENT_APP and the then OnInit

src/HeeksCAD.cpp|77|IMPLEMENT_APP(HeeksCADapp)|

src/HeeksCAD.cpp|172|bool HeeksCADapp::OnInit()|
src/HeeksCAD.h|151|virtual bool OnInit();|
src/propgrid.cpp|604|virtual bool OnInit() { wxPGGlobalVars = new wxPGGlobalVarsClass(); return true; }|

I’m not sure what the deal is with the propgrid.cpp but what I’m looking for is the HeeksCAD.cpp and HeeksCAD.h

Ok… Time to start poking around..
One thing that caught my mind was:HeeksConfig config;
HeeksConfig is object declared here

// HeeksConfig.h
// Copyright (c) 2009, Dan Heeks
// This program is released under the BSD license. See the file COPYING for details.
#include <wx/config.h>
#include <wx/confbase.h>
#include <wx/fileconf.h>

class HeeksConfig: public wxConfig
{
public:
HeeksConfig():wxConfig(_T(“HeeksCAD”)){}
~HeeksConfig(){}
};

This sort of takes care of program variable automatically for you depending on which OS your in.
It will stick setting in the registry or an INI (in windows) or could be /etc or the home directory..
I found my in jonas@Ubuntu4:~$ locate .HeeksCAD
/home/jonas/.HeeksCAD

Takeing a look inside the file looks like this:

heekscad todo: Seems like view should pop up as last one saved.  I suppose that will show up.. one day..

Hmm… What next. In the heekscad.H I found some very interesting function definitions that look interesting to me.
void OpenXMLFile(const wxChar *filepath, bool undoably = false, HeeksObj* paste_into = NULL);
void OpenSVGFile(const wxChar *filepath, bool undoably = false);
void OpenSTLFile(const wxChar *filepath, bool undoably = false);
void OpenDXFFile(const wxChar *filepath, bool undoably = false);
bool OpenImageFile(const wxChar *filepath, bool undoably = false);
bool OpenFile(const wxChar *filepath, bool import_not_open = false, HeeksObj* paste_into = NULL);

Playing around I opened a filed called Bridge.dxf that I downed loaded somwhere off the net.  See if I can follow how all this is happening.. I think that’s something for tomorrow morning..

This is a little sample Code::Blocks project file that I got to work for Heekscad.  HeeksCAD is evolving pretty quickly.  There is discussion on the the heekscad about a option under development RUNNINPLACE which will be far more interesting that this..   The roadblock I ran into using Codeblocks is the program looks up the graphic icons.
The Makefile install executable as
/usr/local/bin/HeeksCAD
The executable basically backs up one  and then looks folders:
/usr/local/share/heekscad/bitmaps
/usr/local/share/heekscad/icons.
Basically,  if you create the executable in the source code directory, that graphic elements are not stored that way… And if  target /usr/local/bin…  you require sudo.   There is probably a way around that but I just want to start play with the code to see how it works.
Basically I created a folder in for the the executable in my local directory (no sudo required)
/home/jonas/HeeksCAD_Executable_NotTheBestSolution/bin

And dumped the graphics in:

/home/jonas/HeeksCAD_Executable_NotTheBestSolution/share/heekscad/icons
/home/jonas/HeeksCAD_Executable_NotTheBestSolution/share/heekscad/bitmaps.

This is a crappy project file but it was good enough to get me going. (I haven’t done this for a we’ll see if this works. Hear’s the link

It’s way too late and I should be in bed…. but this is way to0 fun…

Anyway… I downloaded the source for HeeksCAD has was able to get it to compile with the existing makefile.  (So… I know what I got is good)…
I copied the project over to another folder and deleted the object file and am working on trying to get to run in code::blocks.
I’m widdling away at the errors and learning a bunch in the process.

This is where I left off with the errors’

I think I might need to add some stuff to the Code::Blocks project file.
I searched for tinyxml and this is what I came up with:

Ok... That took care of that problem.... Recompiling here the next set.
This one seem to be a little more tricky..

I think I might have to compile some more tinyxml stuff…

This is a note to self.  This stuff looks very interesting to me.  I wonder if I could apply it to some of my Stirling engine stuff research… That is after I get the other million and one things done that I need/want to get done…  So much to do/ so little time 🙁
