Activating an Existing Work Plane
Activate an existing work plane as follows:
- Select Modeling | Connection | 
        Distance > 
        Activate Workplane. Work planes in the building model are highlighted in color. - Select the desired building component to activate the work plane it is on. For example, select either of the following:
- A truss volume to which you have added parts from the truss library.
 - A wall to which you have added parts from the profile library.
 - A wall with constraints between its parts.
 
 - The dimension constraints added earlier to the work plane will be displayed.
        

 - If necessary, rotate the model until the work plane is perpendicular. For example, select 
        Select From Model from the tool strip, and click a surface of the building component. - Edit the components on the work plane. You can add and delete profiles, joints and geometric constraints.
 - Then, close the work plane. Select Modeling | Connection | 
        Distance > 
        Close Workplane.
