Solid Custom Hatch

Good morning,

 

I am trying to set up a custom hatch pattern of a rather detailed granite stonework that we use quite commonly in the practice.

I thought I alsmost had it, but sadly when I try to apply the hatch it just comes out as solid. AutoCad attempts to "automatically adjust the hatch scale", but sadly this does nothing.

 

We are using AutoCad LT 2012 and I have attached the custom hatch pattern. Does anyone have any suggestions / solutions?

 

Kind Regards.

Have you tried tested larger hatch scale?

Hi 3Wood,

 

Yea, I bumped it up to the maximum scale possible (and minimum just in case) and it still comes out as a solid hatch sadly.

Maximum scale? Where are you doing that exactly?

Hi Pendean,

 

Sorry, when I say "increasing it to the maximum scale", I just meant using the "hatch edit" command. Basically, I would assume that it comes out as a solid hatch because the hatch was at too small of a scale, but even increasing the scale to "99999999" has the same solid outcome.

Post a DWG with the hatch in it and problem present, let's all have a look at it in action.

Hi Pendean,

 

I've attached a simple file, just a rectangle with the granite wall hatch applied to it. I have left the scale at "1000". No matter what the scale is though, it always comes out solid.

 

Just in case it comes out differently on your screen, I've also attached a screenshot of what I am seeing.

 

I also attached the actual .pat in the first post if this is required for you to view it properly.

 

Cheers.

You don't see too many 4MB PAT files. Where did this originate and has it ever been used successfully in any version of AutoCAD?

Hi rkmcswain,

 

It's a custom hatch that I attempted to prepare myself. I have to say I've never attempted creating a hatch before and it is of a very detailed pattern. I used "DrawHatch" to create it. I only made it a couple of days ago and no luck in getting it to work on any computer sadly.

 

We are using AutoCAD LT 2012 in our office if that's important.

 

Cheers.

AutoCAD doesn't know what to do with your custom hatch: it won't even explode it.

My guess is it's too complex or just has a major error in it somewhere (sorry, way too long for me to read through every line).

I agree with Dean. I'm not saying a 4MB hatch pattern is not possible, but I've never seen one so large and it's not working.

Is this the command you used?

I used SCALE command to scale it up 1000 times and AutoCAD still complained it's too dense a pattern when I saved and reopened it. It still showed solid: even HATCHEDIT's scaling did nothing in either direction.

I think it is just badly coded by that app.

Using Acad, draw a sketch of what you WANT your hatch pattern to look like.

 

DEAN:  Wouldn't the scale command just create a larger shape which in turn would multiply the area that the hatch needs to cover (thereby causing even more of a memory issue)?

Hi Pendean,

 

I had a feeling it might have been. Any tips on simplifying hatches? Or perhaps even creating them in the first place? It's an alien subject to myself sadly, but resolving this particular hatch would be extremely beneficial to our office. We're currently copying and pasting it on to walls then having to trim / delete and excess, wasting a lot of time. Haha.

The 'how-to' has been documented by Autodesk pretty much the same since the beginnings:

http://docs.autodesk.com/ACD/2014/ENU/files/GUID-A6F2E6FF-1717-44B6-A476-0CA817ADD77E.htm

 

You might also search around to find something that is close enough for your needs:

http://www.dotsoft.com/acadhatch.htm

http://www.cadhatch.com/

http://cadtips.cadalyst.com/node/tiplisting?tid=100

 

As a last resort, you could also look into using the Express Tool "SuperHatch"

Hi Doni,

I created a quick dwg of the hatch that I am actually trying to create. I've attached it to this post. As you can see, it's not exactly a straight forward one, but it looks very professional when applied. The only problem is it takes hours to apply it by copying/pasting/trimming.

Thanks for the guide Swain, although I have a feeling that coding something like the attached pattern might be slightly out of my league. Haha - that's why I used this "DrawHatch" software.

Thanks for the link to the other libraries though, there are some very useful looking ones in there.

Attached is a drawing showing your pattern as used by SuperHatch.

Ahhh, that is what we're looking for! Sadly it would appear out version of Autocad doesn't have "superhatch". We're running AutoCAD LT 2012... Going to assume this is another feature not meant for LT?

Oops, missed that from the beginning.
There is a dedicated AutoCAD LT forum here:

You are correct, LT does not include the Express Tools, nor can it use them.

Ahh, OK, sorry I missed that one. Thanks for all your help regardless. I'll take the query there and see if anyone has any further ideas!

 

Cheers all.
