Catia V5 | Catia V6: Methods for Creating Curves for Corners

- Here is a good reference for creating curves that are clean and easy to modify for your corner surfaces.
These are tried and true and yes very parametric.
Again and again those tips are one of the best I found. You've taught me a lot, thank you, Steven!
My pleasure
Excellent exercise and explanation, very good work and show different ways of solving corners with Catia, thank you very much for sharing, remember many things, but done in Catia V4
Great video cleared my doubts.. Thank You!
I just tried this method in Autodesk Inventor 2016, and as I went along, I discovered doing this was MUCH more tedious for a number of reasons:
1. In order be able to control continuity along sections in a Loft, *the sections must be edges on a surface*. Cue a Split feature or a Thicken/Offset to create the edges.
2. *In Inventor 2016, there is no "curve on surface"*, which was introduced in Inventor 2017, and *you can't split curves part of reference geometry*. The latter wouldn't be so much of a problem if you could simply project the fillet edges and the necessary sketch points onto a sketch, except the curves you want to intersect the projected edges cannot be constrained to G1/G2 on both ends relative to the projected edges.
As an example, for the bottom edge of the corner fillet, I had to trim back a copy of whatever surfaces a spline touched (but doesn't rest on), project the trimmed edges as construction geometry onto another sketch, and add a bridge curve between the construction geometry (ensuring G2 continuity), the projecting THAT back onto the face the spline should rest on. That's just for the lower edge of the corner fillet. Rinse and repeat for the top edge of the corner fillet.
In total, my attempt took *67 features* to make. I could cut it down to around 50 if I really tried, but things are still highly likely to break if I changed the original curves defining the original slab surfaces!
I'm becoming increasingly more convinced I'd need a dedicated surface modeler for this kind of work!
how about swept surfaces (with angel to the big fillet) from the yellow curves.
with those sweeps you can intersect the pink and the purple fillet, and the curves.
should be stable as well, or?
+beginner I have built surfaces like that before for sure. Sometimes you make the sweep normal to surface or you use a die line. It creates a simple method to easily update. Just have to be careful that the surface normals do not switch but that is not a huge deal.
Hi ! in min 7:43 , what you slip ? The pink area and the violet area ......all become yellow . Can you explain this ?
More video tutorial for beginners in image and shape please , thank you ! :)
It's just a new Geo Set with different properties set up. When I do the Define n Work Object to the new geo set it places all elements in there.
Hey people cannot see the tools u are klicking on the right so cannot learn... Whats the point in these videos??
