Re: Civil engineering feature implementation (Transportation Engineering)

It's there. At least for arcs and tangents. Not promising spirals any time soon. lol
When you need to use it, let me know.

Re: Online paid coursework featuring FreeCAD

To me these are fundamental skills a student should learn before applying them directly to civil engineering work. At this point, I don't have time to build a curriculum for the near future, but I've continued to pick away at it. I've decided (thus far) on going through some hands-on projects to de...

Re: Civil engineering feature implementation (Transportation Engineering)

Just a note, I've updated the Trails github to start tracking issues / milestones and have set a rough roadmap for the 0.1 release... which is going to be a while yet, I'm sure. Also have added support to the model for finding the station / offset of an arbitrary point along the alignment and comple...

Re: First actual parametric model

So one of the other things I've noted about 3D modeling is that it seems a bad idea to build sketches off of faces. That is, the model is more stable if a sketches built from a shapebinder, which is perhaps derived from another sketch. In order to accommodate that, I used multiple bodies (though pro...

Re: First actual parametric model

Hare , miror isn't the right tool : your part is oriented SW , if you miror , it's becam oriented NW , the rigth tool is Polar Right. I tried it and got the main body to work, but it seemed to make a mess of the rest of it. Probably because I don't know how to design an object to make good use of p...

If you need draw a symetrical part , start your first sketch on world repers (XY , XZ or YZ ) it's more aesy to do miror or polar
It wasn't clear to me how to mirror the body along an axis, which is why I broke the box culvert into two parts...

Re: First actual parametric model

- If you look at the dependency graph, you see several links going out of allowed scope. I completely forgot about the dependency graph. Whoops. Will take a closer look. - master_alignment: I always try to fully constrain sketches. Especially MasterSketches. - headwall_sketch: instead of repeating ...

First actual parametric model

So I've been playing around with building a box culvert that's parametric. It's a bit of a mess, but I tried to follow what appear to be best practices for designing 3D models. If anyone is willing to take some time to look, I'd appreciate feedback on problems with my layout or better ways to have m...

Re: Parametric objects - guidance please

It is usually easy to avoid this line, because all the special methods of the Proxy (execute(), onChanged(), etc) receive the FeaturePython object as first argument, so you can pass this reference to your other custom methods, without needing to store the FeaturePython object in your proxy. The err...

I put my guidelines group inside of Alignments group. When I try to save, it gives this error.
Hmmm... Something changed. I'll take a look in the next day or two.
