Re: Part solids under PD body

What is the benefit over the usual methods, using the part as base feature or putting it into the part design Boolean? I did not test your method, but could imagine that it does not combine the box to the already existing part design features, hence lead to overlapping. Such things do not happen wit...

Re: group child: getParentGroup() does not work

hm that is a bit tricky. 1. It is clearly a bug that it does not detect the GroupExtensionPython as group, that must be fixed 2. It is correct to not check for derivatives, as the idea was to only get groups and not the derived GeoFeatureGroup (See comments in the code) So a possible solution would ...

Re: Feature Request: Modifying used precision.

Freecad internally works with exact mathematically representations, hence there is no real precision involved ( only when combining individual entities into complex shapes, but that is a different topic). What you see in sketcher is a pure visualisation issue: 3d graphics only do triangles and lines...

Re: [enhancing loft feature] : adding guide curves to control the loft

You can add multiple sections to a sweep, which is basically the same as a loft with guiding. In the weep task dialog bottom field, there you can choose to use multiple sections.

Re: Using Gmsh as triangulator for CAM

Does anyone have much experience with using Gmsh? Could it be run against OCC bodies easily to generate the triangulations? GMSH is one of the two meshers used in FEM workbench, there you can easily access and use it (also for 2d triangulation). Have a look at FEM_MeshGmshFromShape . If you want to...

Re: FreeCad 0.19 inhibits desktop during STEP (.stp) file load.

Ah, I understood the post differently, thougth it's about using 100%CPU and with that locking up the other UIs. If its grapping some systmem inputs you are rigth, that would be a bug.

Re: FreeCad 0.19 inhibits desktop during STEP (.stp) file load.

This should, in my view, never be so. The slowest things are us, and our mouse, and our typing. The highest priority should be given to the slowest stuff at an acceptable sample frequency. The interrupt is tiny, from when it can return to the really big task. We should never feel out of control, lo...

Re: [BUG] Line.intersect / intersectCC between colinear line -> Segmentation fault

As it is a regression one could also report it on the occ bug tracker, usually those regressions are fixed by them.

Re: Question about beam calculation with calculix

I intuitively assumed the beam is calculated with the profile I specify, and the 3d option is only for visualization purposes. So like a normal hand calculation calculix calculates bending moments etc. from the beam, and deflections and stresses than from those moments and the profile. If this optio...
