B-spline_xyz? for surfacedesign
Hello together,
our implant was designed using Siemens NX, now we have to use FreeCad for another version of plate. the idea is to create the solid using surface WB
First step: creating an outline of the part using a B-spline in xy
Next step: add the correct z-value to the B-spline points to follow the top-surface. -> B-spline ->data -> points OK and then click gorden-profile
now you see the actuall line.
It works, slow, but it works and, I am sure, the gorden line button is not correct for this work, but I have no idea what to do to increase.
Any ideas are wellcome
thanks

Re: B-spline_xyz? for surfacedesign
Should I merge this with the Curves workbench topic? If not, then you should make clear that it is about this addon workbench by using an appropriate title for the topic.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.
Re: B-spline_xyz? for surfacedesign
I understand that it is part of B-spline, how to get a third parameter for the coordinates.
But I am not familiar with the structure of Freecad, only pragmatic user.

Re: B-spline_xyz? for surfacedesign
arch contains draft and draft is a real 3d tool, it is often wrongly described as a 2d tool.

Re: B-spline_xyz? for surfacedesign
My problem is to activate the third coordinate-value, there is always the result in xy or yz....
There is a hidden button to get your results.

Re: B-spline_xyz? for surfacedesign
It works, FreeCad reinstalled.
But in Combo-view I see line not Bspline.
Thank you Thomas, its a big help.
