If you want to check the geometry when entering model data, you do not need to set any Dimensions. The Tools menu offers various functions for measuring distances and angles.
Click the objects for measurement one after the other in the work window. A dialog box provides information how to proceed. The "Distance" or "Angle" of the point available for the current cursor position is also shown in this dialog box.
Once you have defined the last object, a dialog box appears with the coordinates of the reference points and the distance or angle specifications.
