Hi,
You will cut off the upper parts of the wall with Solid Elements Operation
s or SEO. Look through the Help menu and also do a search on the Forum
for similar questions. This has been a hot topic, so there are many posts on it.
To lean the wall forwards or back, open the Wall Default Setting and look
under Geometry and Positioning, there you will see inclined walls under the
Wall complexity sub panel.
Please indicate your AC version and OS by filling out the signature line in your porfile page. See my information at bottom of post.
