Copy and paste works. Inside and between files.
Without any lag :?:

---

Hatch Patterns are included in the dxf.
Property 'From Entity' = True and usually at the bottom in the pattern list.
These supersede the installed ones.
Without the .pat file installed Qcad can not revert to it.

There should be a file HPZG60N1.pat (or hpzg60n1.pat) in
../Qcad/Patterns/ under imperial and/or under metric.
One needs both while swapping between drawings with different units.
Qcad keeps the old measurement system while converting to another unit.
Patterns are loaded only once at boot.
After you save it under Win, make sure the file is there. The UAC may intervene.

A most simple pattern.
Good numbers maxed out in digits would be: e_geek
0.577350269189626
1.15470053837925

What gives: (and fit 80 chars)

Code: Select all

60,0,0,0.577350269189626,-1,1.15470053837925,-1.15470053837925
120,0,0,0.577350269189626,1,1.15470053837925,-1.15470053837925
I do not favor negative dY (-1) and suspect problems with it. :?
Properly addressing the 1e right hand clone with dX & dY gives:

Code: Select all

60,0,0,1.73205080756888,1,1.15470053837925,-1.15470053837925
120,0,0,0.577350269189626,1,1.15470053837925,-1.15470053837925
I can toggle between solid and patterned whatever I do.
It doesn't care what variant of the above. As long as the pat file exist.
Remark, I am hatching at 0 degree and rather near the origin.

Yes, turn solid on - copy paste with no lag - turn solid off. :)

Aha, that was my problem. I was messing in the snapshot version and didn't copy over the hatches. I see the hatches work so I don't think about copying. Well, so toggling the solid on hatches is one way to see which patterns I forgot to copy over. :lol:

Thanks. Although in my case (I only use the first zigzag line to fill out a box) I doubt that those extra digits will be needed.

Question it if you like.

Well, I was using it at max 220. That's why I probably didn't see it.
I'm learning more and more about hatches. Your answers force me to understand it all. e_geek

The digits ...
It may sound off-topic ...

Rigorous coding pays. two-folds.
A pattern as your hatch but coded angled 60.5° instead of 60°
and using the proper numbers will even time out at some point ...

That is more than just lagging, with some firm Hatches you can put coffee in that time.

Besides that it will be hard to put it in a 80 character line.
It will lose stability because there is no place left for the necessary digits.

----

The 'solid' work aroud is fine up to the point where you have to toggle back.
With patterns included in the file that's out of the question.
But, it kills the zoom lag in Layout too.

I tried it out on the 2e file in https://www.ribbonsoft.com/bugtracker/i ... sk_id=2063
Of no use if you aply this to all the Hatches. Looks odd as solution.

In the process I lost the H1INSUN1 Hatch .... :oops:

:!: :!: :!:
Just the 3 Hatches with gravel.pat set to solid is the better solution the Layout.
And it looks rather pleasing too.

The Pattern IS the LAG !
