Terrible Hatch pattern issues!

[Elisabeth83]

Hi, I need to create a hatch pattern for a flooring tile that we have currently starting using and I am having real issues getting it to work!!

The pattern is meant to be tiles set in a brick type style but with a rolling offset, but the tiles are different sizes - I have one row of 300x600, then a second row of 148 x 600, then another row of 300x600, then another 300x600, then a row of 148x 600, followed by another 148x600. This is the pattern end and needs to repeat itself. I have attached a line drawing of what it needs to look like.

 

I can get a very basic line drawing showing 300mm and 148mm for the first two lines but then it all goes wrong!

 

Any help would be greatly appreciated as it is driving me mad!!!!!

Can you get access to a workstation with AutoCAD full? This way can use the tool recommended here to create desired pattern.

 

If not, it will help if will post the pattern you defined to allow someone to take a look and try to correct it.

[Elisabeth83]

Unfortunately no access to AutoCad full:(. I started trying just to get the horizontal lines correct - 0, 0,0, 0,300 etc then I added my next row of 148 - 0, 0,0, 0,448. this gives me a first horizontal line at 300mm up and then the second line 148mm higher - but the problem starts after that as each of those lines then repeats itself ( at 300 and then at 448) which makes it a real mess (AAHHH!)

 

Is there a way to stop them from repeating? Is this even possible?!!!

I would comment that the pattern does not seem to be repeating symmetrically. What happens at the top boundary? Do the bottom two lines repeat at the edge? Perhaps a hatch is not possible

[Blackfish]

Maybe something simple like that...

Try this pattern of staggered tiles of varying heights - if the verticals aren't exactly where you want them then adjust their x co-ordinates (second value on each line commencing with 90,... or -90,...)

Wow, I did the same pattern by hand (10 hours earlier!) as hatch pattern editor

[hugha]

You're most welcome - it's a very simple pattern and took but a minute or two to do.

 

But I'm very curious as to why a tiling hatch pattern should be specified in metres. In my local experience building CDs are drawn in mm.

[eldon]

The OP gave dimensions in mm, and some of the hatch patterns submitted look as if they need a curious scale factor to give the actual dimensions needed.

 

How about the grout space, or are the tiles glued edge to edge?

[MSasu]

The pattern I have submitted was extracted using the tool that I have suggested above – the OP isn’t able to use it due to LT limitations. That hatch patters generator create the pattern from a 1x1 units sample – this was probably chosen for consistency between different patterns.

For sure the grout space wasn’t considered in any of the submitted solutions, but neither was asked for in OP’s request.

 

On AutoCAD full there is also SUPERHATCH command from Express pack – but I’m not aware that it let user export the PAT file too.

[eldon]

I am of the opinion that as the OP had a specific dimension to get a custom hatch pattern, it would be useful, and kind, to give a pattern that would only need a scale of 1 to give the dimensions. It is a custom hatch pattern and not one for general use.

 

Perhaps the OP has forgotten the grout lines

[Blackfish]

The OP gave dimensions in mm, and some of the hatch patterns submitted look as if they need a curious scale factor to give the actual dimensions needed.

 

I had in the past problems with such 'big' numbers in hatch patterns, so since that time I have never used real sizes of items. I don't remember what exactly it was, but it caused errors. You have to use some scale, 1000 with my pattern.

 

How about the grout space, or are the tiles glued edge to edge?

 

It's without grout space as the OP showed on image

[Blackfish]

But I'm very curious as to why a tiling hatch pattern should be specified in metres. In my local experience building CDs are drawn in mm.

 

Why? Because for unknown reason hatch pattern with such 'big' numbers doesn't work and error message is displayed

Have you tried your pattern in AutoCAD? I tried your and I could use it because of error... And it's not the common one with extra return at the end.

 

Sorry, the error appeared only when I tried use it as a separate (external) hatch. It works, when I pasted it into acad.pat. Apologies.

I guess you are right. But due to the complexity of the pattern generated by the said tool, it will be quite difficult to scale it.

Have try your pattern? It's not exactly what the OP wanted.

As I said in previuos post for unknown reason an error message appeared when hatch pattern contains 'big' value numbers

[hugha]

The pattern I posted works fine at 1:1 scale. Here's a 2000mmx2000mm patch hatched with it:

 

 

Grout lines require suitably arranging rectangles and it's a matter of taste whether the extra complexity is required. It's quite easy to do but can burden the drawing with unnecessary detail. Note it's possible to suggest grout by using a thicker pen with the simpler pattern.

OK. If everybody wants 1:1 scale HYG:
