As you see, I can speak with authority on this subject. I have used MiniCad since version 1 for my civil engineering and survey drawings since 1985. The property line feature on my version 8 works great but you must realize there are some mathematical errors in the very small decimal places, so you must be aware the figure may not mathematically close. Second, the 90? error submitted by another post, is not associated with the PL tool, but on angle entry from the VectorWorks desktop. Any manual entry is considered to be Polar coordinates which are referenced as 0? is along the positive x axis, hence N89?E is 01? on the data entry boxes on the desktop, accordingly S89?E is -01? on the desktop. To help clarify this in your mind, go to the local library and check out a surveying manual and a trig book and make the comparison. I find this program much easier to use than the AUTOCAD programs because of the scaling factor and line weights are the same as actually drawing the plats and plans. Enjoy.
