[fixed] projection group view is much too large

[uwestoehr]

It seems my recent SVG fix introduced a regression because:
- create a section view of a projection item view

result:

Code: Select all

Error - Could not load hatch into SVG renderer for C:/Users/USti/AppData/Local/Temp/FreeCAD_Doc_69c132b3-fb97-4455-be74-4f8f8e03d450_bb6d8f_6372/FreeCAD_Doc_69c132b3-fb97-4455-be74-4f8f8e03d450_bb6d8f_6372SectionViewSvgHatch.svg
SVG tile count exceeded: 10001

I have no idea yet since all my fix did, was adding missing SVG namespaces.

Don't think it is your change. 10001 64x64 tiles is a big area. Is the section face large?

SVG tile count exceeded: 10001[/code]

Try changing this parameter:

Code: Select all

    hGrp = App::GetApplication().GetUserParameter()
        .GetGroup("BaseApp")->GetGroup("Preferences")->GetGroup("Mod/TechDraw/Decorations");
    m_maxTile = hGrp->GetInt("MaxSVGTile",10000l);

OK, there is a different issue with TD.
I see that you set up a new preferences parameter to increase the tile number. But the issue is why this number limit is exceeded.

My test file consists just of a simple block 240 x 80 x 80 mm:

top-joint.FCStd

- take this example file and create a Projection Group

result: you get a huge view

- now select a view of the projection group and insert a section view

result: now you get the 10001 tile limit

So the issue is not the section view but the wrong size of the projection group view.

What is the Scale for the Projection group? Here the PG is big, but not huge, at 1:1.

I don't hit the limit event at 8:1.

Good point. I think it is a bug in the preferences, because these are my preferences settings (using todays' master):

and when I create a new projection group view I see this in the dialog:

dialog view

So "auto" scaling sets the scaling to 5:1. I don't know why. These are my parameter settings:

When I accept the proposed settings of the dialog. I get a Front view. Then I select this Front view and create a section view, and voià:

section view tile exceed

This commit git commit 3a42205cb4 should fix projection group autoscale .

Many thanks! Works fine.
