Opening an .scad file its parts are put to the wrong coordinates on screen

[infocean]

Thank you folks, looks like you do great progress on this post.

I am using a Mac 10.15.7 Catalina, my OpenSCAD is 2020 01 and my FreCAD is 0.19. The program I uploaded is slightly different from the program I made the first set of pictures, but the problem, the misplacement of the parts are the same. So whatever the uploaded program is creating, use that for your testing and ignore the pictures I attached to the first post.

What do you think 0.20 will be out? Or what is your estimate for a fix for 0.19 ? Unfortunately Apple is not keen to update Python in older OSs, mine has:
janos@MacPro ~ % python --version
Python 2.7.16

and I do not want to mess too much with the official release of the OS.

Now, that is interesting, that TechDraw workbench is creating the 2D image right although the representation after the import is wrong. Does TechDraw work from the original .scad file? Or there is a hidden representation made by the OpenSCAD workbench and Tecdraw is using that hidden representation?

Thanks again,
Infocean

0.19 was just released a few weeks ago, so 0.20 is still a way off. Your best bet if you need this in the short term is to grab the two files I linked to and replace the files in your FreeCAD distribution with them. You should be able to right click or option-click on FreeCAD in your Applications folder and choose "Show Package Contents". That will open up a folder that contains Resources -> Mod -> OpenSCAD, which contains all of the Python sources for that workbench. The two linked files replace the files in there with those names.

Or if you are not happy doing as Chris advises install Workbench https://github.com/KeithSloan/OpenSCAD_Alt_Import using the Addon Manager as per the instructions in the Readme. With it installed use FreeCAD | File | Open your file and you should get a prompt as to which importer to use.

I too am using a Mac 10.15.7 Catalina, my OpenSCAD is 2020 01 and my FreeCAD is 0.19.

No idea. How are you requesting TechDraw deals with the scad file?
If I open the scad file from the TechDraw workbench it just invokes the OpenSCAD importer

Nice work Chris!

I am all set at this moment. As I read the manual it says, that I do not need to be in the OpenSCAD workbench to open an .scad file. Because I do not do any additional work in that workbench, I go to the TechDraw workbench immediately to create the 2D images. Much simpler then retrace the .scad created image in InkScape.

In TecDraw I just insert a page using a template, then I select all parts I need in the Combo view and hit the Insert a View button. Aster the insert I scale it to fit on the template nicely and half the thickness of the lines. That is it. Now I have to learn how to att annotations and comments and numbers, but that will be the easier part I guess.

It would be nice if the 2D drawing could have been done in OpenSCAD, but I have not seen anything related to that.

About 2 years ago I looked at FreeCAD, but there was something missing in it what I thought I need and went with OpenSCAD. Looks like, here on I need to work with both.

Thanks again,
Infocean

Looks like my satisfaction was premature. The problem now is the import of cross sectioned models from OpenSCAD.

The model in OpenSCAD was rendered with F6 without any complain. The FreeCAD import cuts some of the modules, but leaves others intact. FreeCad also shows some 2D structures, not really present in the original file. The cat was done in OpenSCAD like this:

difference(){
union(){
module1();
module2();
.....
.....
modulen();
}
translate([0,-25,12.5])
rotate([0,90,0])
linear_extrude(height=70,center=false,convexity=10)
polygon([[0,0],[25,0],[25,25],[0,25]]);
}
Question : Can I do the cross-section cut inside FreeCAD after the import of the .scad file?

Thanks ahead,
Infocean

[chennes]

The extra 2D structures are coming from a few places in the importer where an object used in another operation is not being correctly hidden. I'll get those taken care of as I work my way through the unit tests. No ETA on that, though.

Regarding the cut -- are you able to post your OpenSCAD file here? Or a pared-down version of it that exhibits the problem?

[infocean]

Hi Chris,

I can send you the file privately, if that is OK. Were you able to see the crash log piece I sent earlier the same way?

[chennes]

Yes, that's totally fine. I saw your crash log, but it doesn't give much of a clue about what was going wrong: something failed inside OpenCASCADE, but that's a pretty broad range of problems!
