Scaled Block with hatch

[Husky]

Hi,

I learned after playing around (Customer question) with an inserted and scaled block with hatch that the Scale Factor for the Hatch will also be affected by the scale factor. Affected or not depends on the scale direction (x or y or x and y).

In my opinion it would be nice that a scaled hatch will keep it original Hatch scale - would that be possible?

Hi Husky

This is what I regogniced as well yesterday at my tests when I was playing arround. So I changed from hatch to colour filling. But hatch would be more professional...

Hi Husky

I think the scaling of the hatches is correct, if I have a section of timber with hatching at 1:25 then I rescaled at 1:5 I need the hatch to scale accordingly otherwise my hatching would not be correct.

Hi Clive,

... need the hatch to scale accordingly otherwise my hatching would not be correct.

not what I learned. Not matching hatches are chosen to show clearly that this hatch has to identify a different section/part/material etc.

The shape of a section has nothing to do with the scale of a hatch. If I use the same timber with different sizes and I like to mark it as the same timber typ then the hatch has to be visually identical. If the hatch is different then it is chosen to show clearly this difference.

The same would be with mirroring a hatch. If you mirror a hatch in QCAD it will treat it like text. Size, direction and scale will stay like the original source because not matching the source would be incorrect and isn't correct readable ...

This "Hatch thing" was invented to show in a black and white drawing sections, parts etc which belong together and which not. Today we could use different colors ....

Husky: unfortunately, as far as I know, that is also Autocad behaviour and should probably be implemented the same way in QCAD. Although Autocad will also "squeeze" the hatch pattern if non-uniform scaling is used. QCAD simply cannot do that at this point.

Thanks Andrew for this Info.

Husky,

I am talking about the scaling of hatches ... not changing anything else!

Husky,

Thanks Clive but I think I understood you correctly.

I'm talking about NOT to scale the Hatch within an inserted and scaled block. That makes no sense to me regardless that AutoCad is doing that on the same way. Yes I understand the goal to be compatible but it feels just wrong and is a kind of uncontrolled effect if I see a result like this simple example ...

How will you explain this behavior to students .....



In my opinion it should look like this ...

@husky: I never wanted to expand my problem with scale like this

But it is in my opinion, it should scale everything. Otherwise I have to do 2 extra steps: control an scale the hutch
