Problem with command bhatch

Summary

I have a problem with command bhatch. This is the operation that I have doing:
 
1. Run vdfCAD
2. Open file "XX1.dxf"
3. Click on "Zoom extends"
4. Click on menu "Utility", command "bhatch"
5. Choose "bdiagonal" hatch
6. Click on "Select curve by points"
7. Click on coordinates x=37644.7, y=-8759.5
 
The process, with random event, infinite loop...

Solution

The algorithm in bhatch - "Select curve by points" is searching ALL entities that are displayed in the screen and also uses an equality that depends on the zoom. Bigger zoom means better equality and less entities on screen means less calculations (bigger speed). So zoom in the area that you want to create the vdPolyHatch for better speed and precision.

So in the drawing you send instead of step 3 : "zoom extends" do a zoom Window (to the area that you want to hatch) to these coordinates : First corner: 37540.7227,-8965.6990,0.0000 Other corner: 37862.6916,-8515.8246,0.0000
