Free Hatch Patterns

Hi All
PLEASE READ
It is good practice to keep the hatch origin near the hatch.
If you go too far away from the Origin, tiles will eventually loose coherence, this is even true
with installed standard hatches eg; AR-CONC.PAT
CVH is looking at some ideas he has, after that is sorted and I have an update on Tile2Hatch
I will redo the tiles that I've temporarily removed for now.


I have removed some of my patterns created by Tile2Hatch Tool, some of my earlier patterns
seem to be ok apart from the QCAD-LOGO that Fails when hatching 100000 , 100000 from zero point
this is not just an error in Tile2Hatch Tool it also seems to happen with AC tool but not as bad eg. 1 line out of place..
Sorry for the inconvenience I've removed some of my patterns and I will replace hopefully soon..
It's mainly effecting patterns that have arcs or circle shapes in them


The Patterns below have now been reinstated see page 4 of this topic
Bubbles-01 ( not included in qcad build )
Bubbles-02 ( not included in qcad build )
Leaf-01 ( not included in qcad build )
Leaf-02 ( not included in qcad build )
Leaf-03 ( not included in qcad build )
QCAD-LOGO ( Included in qcad build )
Squiggle-01 ( Included in qcad build )
Squiggle-02 ( Included in qcad build )
Weaving ( not included in qcad build )

I've Optimised some of my patterns using a Tool Developed by CVH "Tile2Hatch tool © CVH 2020"
I will be posting these on page 3 of this thread, please replace current patterns with these, the
only difference is in some cases file size and other cases reduces the load on the resources and
now line segments are continuous rather than broken between tile patterns..

This is where I'll be posting New Hatch Patterns....
Requests are welcome...
Metric files now included further on in this thread see page 2
Also updated all PAT file header info so it will look as if they haven't been downloaded yet as I had to delete and repost..Enjoy 👌

Cheers

LATTICE-04 [ see angle note on screenshot ] to make it orthogonal..
If you require a more accurate angle the true one is 26.565051deg :-)

QCAD_LOGO
This one is a bit rough as you cannot use arcs or circles in *.pat files
only points and lines...

John,
Are you doing these by hand or do you use the Autralian tool?
QCAD-LOGO consists of 125 lines... :shock:

But thats nothing compared to YUKONRUBBLE.PAT, 4533 lines. e_surprised
Although, Qcad can't handle that one.
Simply google 'YUKONRUBBLE' or 'yukon rubble hatch pattern'.

This topic started before you proposed making custom hatches.
https://qcad.org/rsforum/viewtopic.php?t=6678

I made this one archaic to test my insight in and knowledge about hatches.
Turned out well.
About 48 lines was more than enough for me. :roll:
Serves nothing as insulation hatches and others can be sourced freely from online.

Can you elaborated why LATTICE-04 is defined slanted at 26.57 degrees?
(The definition is with 26.565051 degrees)

Regards,
CVH

Hi CVH

The angle was just an approximation to visually set it orthogonally...and I didn't want to confuse people with too many numbers after decimal place :-)

Andrew is quite happy with me doing these free hatches and is including them in the next release of Qcad Pro and free versions..

I do all the designs by hand and use some tools to convert to lines that need some mods afterwards..
I will update the angle on my post, but really if people are going to explode this and use as entities
they will work out the angle needs to be tweaked a bit :-) Thanks for pointing this out though..

Bye the way I did see the post you refer to, but nobody has followed up and offered free designs that are out of the ordinary compared to the ones you can download, I'm also offering custom ones if people have ideas but obviously when time prevails, I would need to put my business 1st ...

Also elaborating on why I did this this way "at this obscure angle" , have a go at making a seamless version of it orthogonal :-) it's impossible...

FYI I'm attaching a screenshot of how I made this pattern the yellow lines I put there to indicate how the pattern becomes seamless as it is
arrayed horizontally and vertically :shock:

Cheers
John

Hi CVH
I think he was looking for something like this.... in that old post
SQUIGGLE - 01 & SQUIGGLE - 02 Hatch Patterns
Can simulate under floor heating coils.....cheated massively on this one, but it does the job :lol:
Can also be used for insulation like the hatch you did..👌

I know, did I criticise that? e_confused
Never intended.

I was, the question was 'how to?'
For the example I needed the repetitive nature.

Noop, revision included. 8)

Never say to quick something is impossible with computers. :wink:
BTW: added credits and remarks.
Maybe you could include something similar in new ones and revisions.
If you ask Andrew, I think he would be glad to include that too.

From the screenshot is clear we have different approaches.
Your method is more like the old tiles but coded as common patterns.
And now I understand the funny decimal numbers for a pattern with only lines...

Every line segment we see consist in fact of 2 colinear parts.
Many or complex or very fine hatches tend to slow Qcad.
The number of rendered entities counts here.
So there is room for improvement. :wink:

Hopefully the dxf explains enough what I did.
The revision halves the rendering effort.

Qcad has two sets pattern files. Some files are exact clones, some are scaled.
When drawing in Imperial units we only see the Imperial list, with metric only the metric list.
I think its a good idea to create metric counterparts of yours.
For one, because the preview in metric is almost a solid fill. :|
What I do a lot:
As CSV to a spreadsheet, apply corrections, concat to text lines, copy, paste.

And if we didn't say it enough:
Nice work,
blown by the effort needed.

Regards,
CVH

Hi CVH

Nice work and well done :-), as you know I don't use this method of creating patterns I use old way " after all I am 57 :-) "
As for the pattern I never intended it to be Orthogonal just put as an after thought to rotate at angle if required..
I like your Orthogonal one I would change its name to LATTICE-04-ORTH and repost here :-), I think if we add revisions it would get messy
and also this is as far as I'm conserned just based on my design and is a new one.. No need to mention my name in these
"although maybe I will add to future ones so at least people know where they came from". :-)
Revisions on drawings I agree 100% needed but through Cad history I haven't seen any AutoDesk Pat files with revisions and
I'm sure there has been many and they just update with the next version Cad release..

Oh and Andrew must have a conversion tool to convert from Imperial to Metric so no need to worry about supplying Imperial only, have a look below from current snapshot version, he has corrected to proper scale for metric. I'd like to get my hands on this :lol:

I also noted at the top of this feed please scale by at least 25 for metric ( or 25.4 if you know what i mean 😛 )

Again nice work on pat file, can we leave this space now for adding Hatch Patterns and use private messaging instead just so people don't
have to read through all our comments to get to the files :-) see image below.... All the Best John
