Objects may not shade properly when a face of the object is non-planar. If you are reshaping vertex by vertex it isvery easy to make the face non-planar.
The Faces Tool is very useful when working on roof forms. If you have your roof as flat slabs you can use the Faces Tool to select an endface of the slab and lift just that face to tilt the slab. You can also use the Faces Tool to select the top face of a roof object, space jump to a corner handle and then click and drag that vertex to scale the entire face about its center.
PowerCADD writes an extra vertex when exporting polylines. In PowerCADD a rectangle has five vertices. The fifth vertex coincides with the first vertex to make it appear as though the polyline is closed. Rectangles created in DesignWorkshop have four vertices, the fourth vertex connects back to the first vertex.
When reshaping imported objects from PowerCADD be sure not to forget about this extra vertex and keep it coincident with the first vertex.
