Aussparung Sofiplus

How do I give the Aussparung in der Wand in Sofiplus by using dimensions only. Of course i can pick the points, but sometimes I just wanna give that my Aussparung should be for ex. 3x4 and just choose the start point.
When I give the dimensions and click enter, it assigns the second point of a rechteckige Aussparung to whereever my crusor was, thus not using the given width and height at all.

Rectangles are always created in the x/y plane of the current coordinate system. If vertical rectangles are to be created, the coordinate system must be adjusted beforehand. Either via AutoCAD commands or during the command with the “set working plane” option (only for SOFiPLUS elements).
