I have an existing roof on a home.  I am adding on.  What I really would like to do is, separate my existing roof - part to demolish - part to stay the same.  I really want to keep the existing roof drawn in theory though.  Does my question make sense?

I would suggest that you copy your roof in-place.  Then edit the original cutting out the part to be demolished from the sketch, then edit the copy and cut out all to remain.  Now you can join the two roofs as one.  Use the demo tool in the appropriate view.

I don't think I can cut geometry from a roof - I didn't get it to work anyway.  I 've attached an image...the left side is the existing.

You have to create 3 parts, the existing which will remain, the existing to be demolished, and then the new to be built.  You can take the original roof which you have, copy it, then modify one to be just the bit that is being removed, and then modify the original to not include the portion being removed.  To do this, copy roof, open one roof in its sketch mode, and modify the sketch lines to be just the area that you want to remove.  This is a tough process, because you have to keep the same slope, etc. along with the elevations.

Your sketch doesn't tell me anything.  What is existing - left of what?  You know but you don't tell us.  What part do you want to delete?  Believe me, you can modify the roof sketch to exclude the portion to be demolished.... yhou just have to tell us what you want removed.

The left side of the image I provided is the existing building.  The garage and building behind is all new.  I am sorry if I wasn't clear.  I will try three roofs...thanks for you help.
