URGENT: Hatch Problem

[john.uhden]

I am trying to hatch an area of a detail in paperspace with AR-SAND.

No matter what I do, the pattern remains displayed as SOLID, even though its property shows as AR-SAND (or any other pattern I try).  I've audited 3X to no avail.

Any suggestions?

The only work-around I can think of is to leave it solid and make it color 252 or 253 (grayscale).

Nevermind, I quit AutoCAD, got back in, and it fixed itself.

Are there any messages?

I can see you're new around here, so would you please post your drawing (at least that one small part) to test it on?

How large area you want to cover. This hatch pattern is complex so if it exceeds value of variable "MAXHATCH" as a result you receive area filled with solid hatch. 

You can divide hatch area to smaller peaces and change hatch scale. Also check.

(getenv "MaxHatch")

Try to put bigger value. Standard value, if I remember is 100 000

As requested by @ВeekeeCZ  and @Kent1Cooper  attach small sample of your drawing.

I believe you mean the HPMAXLINES System Variable, which could indeed be the issue.

[hak_vz]

@Kent1CooperYou are right. In this case where in AR-SAND is gazillion of small lines HPMAXLINES may be the cause of the problem. It sets the maximum number of hatch lines that are generated in a hatch operation. 

MAXHATCH is the limit of hatch objects in drawing.

Since "it fixed itself", was this an issue of restarting AutoCAD or operating system due to missing updates?

Good to know for future reference.

I am using Civil 3D 2020.2.
I found nothing in the release notes regarding hatching issues through
2020.5.
I wouldn't call restarting an issue. I'd say it was more of a knee jerk
reaction, or like when you're banging your head against a wall. It feels
great when you stop.
