I have some body panels that i recieved as surfaces and had origionally placed on a drawing sheet for reccognition purposes. since that time I have worked on the panels placing extrusions in them to fasten mounting hardware to. Now when we open the drawings the surfaces are hidden and only the extrusions show. The parts havent wanted to be thickened without spending quite a bit of time on them. Needless effort if the drawings will work. If I RMB on the imported surface in the tree i can select show, and the surface shows but none of the trimmed locations show then. Do you have any suggestions where I look next?
Thank you
S-043318 : Why do surfaces that are shown in a drawing view disappear when a solid body is added to the model?
That is a normal behaviour. When the user creates a view in the drawing, if the model is built of only surfaces, the view is in draft quality. When a solid body is added in the model the view goes to high quality. Because surfaces are shown by default in draft quality, they disappear. The user needs to insert the surfaces again in the high quality view from Insert > Model items > Surfaces.
