Hatching

[caddster]

When hatching details on a sheet, we will oftentimes receive this error message: "could not evaluate hatch boundary at all supported scales".

Sometimes if we hatch "thru" the viewport, it solves the issue; other times not. Anyone else having this issue? Any solutions?

We tried the -SCALELISTEDIT - do we need to separate out all our scale factors?

Toggle through the various scales in your file, then re-hatch. That usually
works here.

thanx - I'll try that.

I have found that by reversing the order of pick points for the hatch(es) I have consistently been able to complete the action. I have tried it in both paper space and model space with similar results.

What do you mean by "Toggle through the various scales in your file, then re-hatch." I have a viewport in a particular scale. Do you mean go back to paper space, toggle through, then go back to what the viewport is set at and try again?  I tried this and it didn't work.

viewport scale, yes.

Or do you mean, while hatching, toggle through the choices of scales, then return to the one that I wanted in the first place, choose that, and hatch?  This doesn't work either. The only way I can hatch is to break up big chunks and hatch each separately.

Why don't you start a new topic and describe in detail your issue, and your desired final result/intent, and provide a DWG sample file for everyone to try.

I wonder if you just need to draw a boundary then select it to hatch instead of selecting inside an open area for AutoCAD to figure it out?

My answer turned out to be setting the variable HPMAXLINE to a higher
number. It controls the total amount of lines which are visible (only in a
hatch I think). In any case, the drawing I was working on had a HPMAXLINE
set to 100. The default is 1,000,000. I set mine to 1,000, then 10,000, then
100,000. Each time larger areas could be hatched and at a smaller scale.
This fixed my problem.
