Creating & Preparing Surfaces Properly in CATIA V5

Recently I was given the task to prepare some geometry in a suitable format that would ease the FEA model building time for an Analyst. However the geometry I was presented with had many internal edges and it was an arduous task to remove these internal edges. The problem with internal edges when building an FEA model is that it can be a meshing nightmare! The reason for these internal edges could have been down to a lack of user knowledge, time pressure or even other constraints. For an FEA model, small deviations from the manufactured surfaces can be deemed acceptable within a certain tolerance. The main issue I had to deal with was lofts between multiple sections. The video below shows a brief glimpse into how I tackled this! Sometimes more geometry, more time and more knowledge is an advantage downstream.

If you would like to learn how to create surfaces more efficiently or would generally like to know more about surfacing in CATIA V5, please visit our Training Section and have a look at our CATIA V5 surfacing course. The above video is just a fraction of what is taught in the course.
