EM.Picasso has a special feature that makes construction of planar structures quite easy very convenient and straightforward. '''<u>The active work horizontal Z-plane of the project workspace active trace or object set group is always set at as the active work plane of the active traceproject workspace.''' In [[EM.Cube]]'s other modules, all objects are drawn in the XY plane (z = 0) by default. In [[Planar Module]], </u> That means all new objects are drawn on a horizontal plane that is located at the Z-coordinate of the currently active trace. As you change the active trace group or add a new traceone, you will also change the active work planechanges accordingly.
You can activate any trace or embedded object set at any time for drawing new objects{{Note| In EM. You can move one or more selected objects from any trace or embedded object set to another group of Picasso you cannot modify the same type or Z-coordinate of different type. First select an object in the project workspace or in the Navigation Tree. Then, right click on the highlighted selection as it is set and select '''Move To >''' from the contextual menu. This opens another sub-menu containing '''Planar''' and a list of all the other [[EM.Cube]] modules that have already defined object groups. Select '''Planar''' or any other available module, and yet another sub-menu opens up with a list of all the available traces and embedded object sets already defined in your project. Select the desired group, and all the selected objects will move to that group. When selecting multiple objects from the Navigation Tree, make sure that you hold the keyboard's '''Shift Key''' or '''Ctrl Key''' down while selecting a group's name from the contextual menu controlled by its host trace.}}
EM.Picasso does not allow construction of 3D CAD objects. Instead, you draw the cross section of prismatic objects as planar [[Surface Objects|surface objects]] parallel to the XY plane. [[EM.Cube]] then automatically extrudes these cross sections and constructs and displays 3D prisms over them. The prisms extend all the way across the thickness of the host substrate layer.
