How to make this 3D Spline and corner of the curved surface coincident?
How to make this 3D Spline and corner of the curved surface coincident?
I want to retain the shape of the underlaying geometry that was the reason I used convert entity. Is there any way to have coincident relation while retaining the shape of the underlaying geometry?
If you spline misses the vertex you must approximate.
Btw. When I work with many 3D-splines, I try to handle them just one or two per sketch even if they seemingly has nothing to do with each other. Does all the grey splines on the picture belong to the same sketch?
I would make a new sketch - do a convert entities of the one sketch you need to go to the vertex - move the sketch endpoint away from the vertex (maybe something like 1/4 of the blue spline) - create a new spline, perhaps with curvature constraint from endpoint of the foreshortened spline and the vertex. Then use these two for whatever is coming later. In extreme cases this operation even requires two sketches.

Same sketch but splited.
Hello Maha,
From your video the spline that you are editing is black meaning that it is fully constrained, and it already has an on-edge constraint - probably this is a convert-entity (take a look at your display/delete relations dialog). If you want to use that convert entity geometry, you can delete the on-edge constrain and then simplify or convert it to a generic or style spline. At that point you can make it coincident and tangent to other geometry.
It deviates from the underlaying geometry.
I would construct the shorter spline in yet another sketch. You can see that when you manipulate the short one the original also changes slightly. If you add curvature relation you will get closer to the original geometry, and you could also add more spline points coincident to the original. The idea is to have a "fresh" spline to connect to the vertex.
The old spline could not be coincident with the vertex, so you must accept a little deviation - but does that matter in the real world? Try to measure the deviation and see.
Finally I would suggest that you hide the original sketch when making the relations to the short one. You are likely to make a relation to the spline endpoint instead of the vertex - and you will be back to square one.
It was not clear from the video. Does this spline have ANY other relations?
If you used Convert Entities you might not be able to satisfy any of the conditions. Even if you delete the relation the spline definition might prevent it to be coincident.
