Hatching slow

danielstofnerautodesk — Thu, 28 Jun 2018 12:31:19 GMT

Hello,

how can it be possible that hatches in autocad work very slow.

selecting them or even picking new points is very very slow like 20-30 sec pauses.

It is really really annoying for my workflow as you can imagine.

I would be almost certain that it is not my computers fault since I´m using a brand new Workstation:

intel xenon cpu E5-1630 v4 3.70 GHz 3.69GHz

32,0Ram

Nvidia quadro M4000 (8gb)

64 bit win10 pro

i use id for 3d rendering and have no problems

Oh i´m using Autocad 2018

please anyone

Not enough info, try again.

Are you selecting a closed polyline for hatching, or are you clicking inside an area and letting AutoCAD calculate the closed area of the hatch?

How busy is your screen: more content is visible and slower the calculations are if you use the point method of hatch placement/creation.

How many unnecessary layers are NOT frozen or Locked at least? The more you have on/unlocked the slower the calculations are if you use the point method of hatch placement/creation.

How far away from 0,0,0 are you hatching?

FYI a Xeon processor is pointless/useless for speeding up one-processor-only AutoCAD. All the above does matter when hatching.

selecting an existing hatchpattern

as well as clicking inside the area. I mostly use it inside object not neccessary inside a closed poly but closed lines.

I did try it also with a closed polyline than it might be fine to place 1 or 2 hatchpattern in different shapes but then it freezes again and i`m talking about solid as well as other hatchpatterns.

I am pretty fa from 0,0,0 106652.86 120784.86 working on a mm scale object

i haven´t yet tested the thing about locked/frozen layers

Could it be possible that it comes from some kind of blocks that i use?

Screen is of course buissy but i expect it to be handled.

It´s a hotel I´m planning with a lot of lines.

It is very possible that your model is created very unfavorable and
thereby leads to a strong loss of performance.

Freeze (not OFF) all layers what are not important for your hatch boundarys is one possible workaround.

If you do not provide the file then you can not give any tips.

One helper option:
Try the Specify Boundary Set option and choose only those objects near to the area that should be hatched.
Autocad then searches only in these objects for a boundary after setting the point selection.

It is not a problem of a specific scene i tried also empty scenes with few plylines

took a long time even there

Without your sample(dwg), one possible problem is a support path to a slow network folder.
Or untested, supportpathes to folders with to many files (specially pat files).

Often the problem is in the drawing.
