Hi.
I attached the script in VB 2010, which draws the insulation hatch, between two points, pointed with the mouse, or entered manually. Points have to be specified in the axis symmetry of insulation. Please also specify the thickness insulation. Hatching takes several seconds (the end is when the field where you enter data Xp, Yp, Xp1, Yp1 are cleared). If you can not see hatch insulation afer you click " Draw", please refresh the drawing. You have to click somewhere in the drawing area and ie scrooll with mouse. To run the script you must have installed on your computer Microsoft.NET Framwork. The script has not been tested on many errors. You have to unzip file.
