Extrude from a crossection

ronald_meijer369

Hi,
New to this forum and I hope someone can help.

I have a design of an enclosure for electronics. It consist of a bottom part and a lid. The lid has a flange to fit onto the bottom part, side walls and a top cover.
I need to make the lid taller to house some more components..
I could create a plane with the cross-section of the side walls that I would like to extrude to make the lid taller.

How can I I extrude the cross-section while leaving the flange and top cover pushed out but unchanged?

Thanks

If you post the url for your document, that will help those in the forum to better assess what you are trying to do.

Hello Ronald. I'm not comfortable downloading a file from an unvetted source. Additionally, the best way to get help is to allow Onshape members to examine your document to see how it evolved. This requires posting the document url or a direct link to it in your post. Not only can you get your problem fixed but you may get some helpful tips or suggestions as to how to get where you want to be. - Scotty

Sorry, but we're talking CAD here. An STL file, at that from some unknown source, is not helpful at all.

Have you read the learning section about how to share your onshape document with others? That is one of the core features of Onshape. Work through this first, and it will be very useful for everything you do in the future.

Then, post that sharing link here, and you'll certainly get help with your problem.

Thanks for your responses.
As you will have guessed, I am new to CAD and 3D printing and I don't really know what I am doing yet.
I have found some tutorials on Onshape and I'll start with that.

Again, thanks.
