Title: Hatching
Post by: rktect3j on January 26, 2005, 10:10:37 AM

Why is it that sometimes autocad says that it cant show hatch because "hatch pattern is too dense or dash size too small".  I have to zoom in real close add some hidden lines that don't plot to break up the space and then hatch it in pieces.  Any solution to this?  I am using ar-conc at scale 1 over a foundation footprint of about 45'x50' with some nooks, not rectagular.

There must be some threshold that ACAD considers the points within the hatch too close together.
I created a rectangle 45x50 feet offset another to the inside 24" and tried to hatch ar-conc
but had to use scale of 1.5 before it would hatch. I did not try below 1.5 except 1 will not work.

CADaver,
 
I was always told not to set the MaxHatch number higher than 100000 due to the fact that it could alter the performance of the program, in a bad way. Is this true?

Depends on your machine and how much time you have.  If it's set to a very large number on a slow machine, and you noodle up a selection, it could be a while before it gets back to you.  But if you have a fast machine, and you NEVER noodle up a selection, go for it.  Mine has been set as you see it here for quite some time and I've suffered no ill effects.

Is there anywhere all the environment variables are listed with their uses?

Thanks CAB, but I didn't see much there on Environment variables.  I'm not talking about sysvars.  How about that PDF, what does it have?

Ah! Did you add that link or did I just miss it?

Well I added the link as it took me a minuite to upload it after the fact. :D

Hi

Personally I think it would be better to link directly to the Authors web site (purely for ethical reasons) -

Direct link to HyperPics web site - AutoCAD Environment Variables PDF (http://www.hyperpics.com/downloads/resources/customization/autolisp/AutoCAD%20Environment%20Variables.pdf)

Have a good one, Mike
