So, first create our sketch. So, let's say I just want our rectangle. So, once we have done with that, go to modeling here concept, here you can see surface from sketches, just select that, automatically that sketch is going to be selected. Otherwise, select the sketch applied here you can do the thickness also i'm just giving point 001 later generate. So you can see. So, that is how we can create on sketch also sorry or surface from these sketches.

So, particularly in the field of C loves up. So, if it is a simple problem It's better to go with the surfaces instead of 3d model. So, so even we can take our snaps also if we want, but normally the snapping here it is not needed but particularly in the post processing. It is all very helpful for us.
