Hi Allen,
Thanks for your questions. The primary functionality of Stardraw Design 7.3 focusses on tasks specific to the particular needs of AV integrators, like showing the interconnections between products in schematic drawings, laying out products in 19" racks, creating custom connection panels etc. As for creating architectural layouts from scratch, yes, this can be achieved but it is not the principle focus of the application; in our experience, our users in the vast majority of cases get floorplans, reflected ceiling plans etc from the architect/consultant/client as DWG or PDF.
To answer your specific questions:
1) Yes, to get a specific length of Line, first create the Line then enter then length you want in the Length field in the Properties Grid.
2) No, 'Snap to Midpoint' is not currently supported. Use of the Align commands is the correct approach in this case.
3) No, the software cannot show where the start of an object, like a Line, might be before you start drawing that Line.
I recommend exploring the movies on
our Movies page to get a sense of Stardraw Design 7.3's core functionality and recommended workflow and I hope that they will help with your productivity with the application.
Kind regards,
