As well the editing I showed you in the last blog, you can also edit the objects that can be created from a Polyline, such as hardscapes, plant groups, spaces, ceiling grids, property lines and so on by double clicking on it.
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.
With the 2D Selection tool, double click on the object. The handles will change from around the object to on the edges of the object. Your 2D Reshape tool is now the active tool. If you move the cursor to one of the middle handles and drag it down...
The object has been re-shaped. You can see the result, the hardscape area has been edited. This is a fast way to edit hardscapes and other similar objects like ceiling grids, spaces and so on.
