EM.Picasso has a special feature that makes construction of planar structures very convenient and straightforward. <u>The horizontal Z-plane of the active trace or object set group is always set as the active work plane of the project workspace.</u> That means all new objects are drawn at the Z-coordinate of the currently active trace. As you change the active trace group or add a new one, the active work plane changes accordingly.
{{Note| In EM.Picasso , you cannot modify the Z-coordinate of an object as it is set and controlled by its host trace.}}
EM.Picasso does not allow construction of you to draw 3D or solid CAD objects. InsteadThe solid object buttons in the '''Object Toolbar''' are disabled to prevent you from doing so. In order to create vias and embedded object, you simply have to draw the their cross section of prismatic objects as geometry using planar [[Surface Objects|surface CAD objects]] parallel to the XY plane. [[EM.Cube]] then automatically Picasso extrudes and extends these cross sections and constructs planar objects across their host layer automatically and displays 3D prisms over themas 3D wireframe, prismatic objects. The prisms extend all automatic extrusion of embedded objects happens after mesh generation and before every planar MoM simulation. You can enforce this extrusion manually by right-clicking the way across '''Layer Stack-up''' item in the thickness "Computational Domain" section of the host substrate layernavigation tree and selecting '''Update Planar Structure''' from the contextual menu.
After a new embedded object set has been defined and added to the Navigation Tree, it becomes the active trace{{Note| In EM. You are now ready to create geometrical objects in the new active trace. Remember that [[Planar Module]] does not allow you to draw 3D objects. The solid object buttons in the '''Object Toolbar''' are disabled to prevent you from doing so. InsteadPicasso, you can only draw horizontal planar [[Surface Objects|surface CAD objects]] as the cross section of embedded sets. [[EM.Cube]] extends these planar objects across their host layer automatically and displays them as wire-frame, 3D extruded objects. Extrusion of embedded object sets happen after meshing and before every simulation.
