Newbie question: I’m having trouble with the offset and push/pull tools. when I create a perimeter by offsetting a rectangle, I then pull the perimeter up to create walls in a room. When I push this wall perimeter back down to align with the original plane of the rectangle, the perimeter disappears. For some reason I think it just started happening after having no trouble with this function for my first few models.
What you describe sound like normal and expected behavior. Push/Pull is designed to remove geometry as well as create it. It’s doing exactly the same thing as I show here where I’ve drawn an arc on the top and pushed it to the bottom of the block to trim the corner.
I was using the push/pull tool to move wall partitions up and down so I can view different parts of a model more easily, so I thought I could raise and lower walls without losing them. There’s probably a better method for doing this, but don’t know.
