Hello,
Sometimes when I use curves/surfaces to trim/split surfaces the trimmed surface has a broken edge. Does this result from the input cutting tool having a build error or because the surface that is getting split has an error in it?
When the merge edge tool cannot repair the broken edge is there a useful way to rebuild the edge without rebuilding everything from scratch?
Thank You,
Please post a small example file with before and after examples.
Then someone will be able to explain the details.
Thanks
Splits in edges can occur when the trim is not tangent continuous. Post an example, wirg the trimming object…
-Pascal
Hello- the object is made up if multiple faces - the edges start and stop at each face. But… I’d say you need to make that fillet differently. I’d break that area up more like this
-Pascal
Does the new outmost corner fillet you built connect to 5 edges?
Hi Justin- The edges on the upper input surface of the right hand red surface have been merged. Not sure if that is what you are asking about.
-Pascal
The corner fillet looks like it connect to 5 edges. I usually use srf from 2,3,4.
Also, why did the fillet farthest to the right get broken into two surfaces if the input surfaces had singular clean edges?
Yes, 5 edges. #3 is just part of the edge that extends all the way North-East.
-Pascal
Was fillet edge 3/4 built from a singular curve and if so how did you get it to connect tangent to edge 4 and 3 on flat surfaces?
curve network or sweep 2 rails tool?
Hi Justin - I was wondering if these flatish surfaces are meant to be flat (they are not) - if so, I would create one single trimmed plane there - a lot of this would be easier.
-Pascal
That would definitely be better, I did need surface 3 to have Z geometry though. I was able to seal everything up in the end.
Regarding your first comment about tangent continuity; do you mean the splitting curve/surface breaks tangency with the surface being cut and that creates broken split edges?
That makes sense! Thanks Pascal.
