We presented various ways before to draw a rectangle with the view size regardless of Model space or Layout (Viewport or Space) in WCS or UCS, in a plan view or isometric, twisted or not. Usages of both Viewport and ViewportTableRecord were demonstrated. We also used the combination type ViewTableRecord, the handy method Editor.GetCurrentView(), and pretty the same logic and code to fulfill the same task.
A bit earlier, we created a rectangle onto the Paper Space (PSDCS) from a Viewport (Model Space) in the same Layout, with the Layout Viewport size. Previously, we transformed an entity picked in a Layout Viewport from the WCS/UCS of the Layout Viewport to the current Layout Paper Space (PSDCS or PDCS). We also transformed something on the Paper back to a picked Viewport in the same Layout.
Last time, we created an EntityJig, which can jig an entity such as Circle on the DCS of a Layout Viewport. In fact, the code and command works for Paper Space DCS (PSDCS) as well.


As can be seen, the Paper Space is in a UCS instead of WCS, so if we create a circle in the Paper Space, it will be projected onto the Paper Space DCS (PSDCS) as an ellipsis. If we jig a circle using our command however, it will be a real circle on the PSDCS.
