With VectorWorks 12.5 you will find it easier to edit the objects that can be created from a Polyline, such as hardscapes, plant groups, spaces, ceiling grids, property lines and so on.
￼Here is an example. Draw an area of hardscape. You can use the hardscape tool to do this or you can draw the 2D shape that you want and then use the Objects From Polyline... command from the Modify menu.
￼Draw an area on top of your hardscape. Use a solid object like a rectangle, polygon or circle.
Select both objects.
From the Menu bar choose
Modify > Clip Surface.
You can see the result, the hardscape area has been edited to match. This will make it a lot faster to edit hardscapes and other similar objects like ceiling grids, spaces and so on.
