[PR #3873] Sketcher: projection of arcs of circle (orthogonal to projection plane) (implemented)

Post by shermelin »

Hello,

I continue with projecting stuff in sketcher.

Here I implement the projection of circle of arcs, when the projection plane is orthogonal to the circle plane.

Hopefully, the rest will come soon ;)

Many thanks!
Could you please describe how the new feature works, preferably with a simple test case? I will then try and document it in the Wiki.

@uwestoehr I just realize checking your reply that I forgot the screenshots!!!

Here they go, and should be self explanatory I guess (let me know if not).

The arcs arcs in the screenshots are always from the same sketch (plane XY). They are projected on XZ for the first 2 images and on a plane that is the rotation of XZ around Z by some angle I don't remember...

Thanks shermelin for this improvements, I find them very nice since it is in a way a very core functionality. Is there something else? Arcs of elipse?

I need to check a bit more, but arcs of ellipses will be next, then most likely arcs of circle and ellipses in the general case. Then, I think we'll have most cases (nurbs seem already in).

I agree on the "core" part. I actually started this work while checking some scripts from path in which fairly convolved algorithms are used to project stuff. My idea, in the end, would be to move all that in a specific core functionnality, available to other worlbenches (base? A new 'geometry' WB?). But that's still some way ahead…
