Size of various point display modes ...

Postby Husky » Sun Apr 13, 2014 7:53 am

QCAD 3.4.7 - I need help to understand this new various point display feature.

Ok - I'm able to set my Point display choice within the Drawing preferences dialog.

Question one: If I decide to use the Mode 0 with the size 50 - what means size 50? (it doesn't change the displayed size at all ... ) :shock:

Question two: If I decide to use the Mode 65 with the size 50 it will actually display the point bigger but it isn't 50 pixel. It looks like always ~20% less than the chosen value.
What I'm doing wrong?

must be a bug - OSX 10.9.2 the points have no thickness, I can't see them but they are selectable!

selecting one and doing a ZOOM SELECTION will hang QCad

olly: Thanks for your report. Zoom to selection is a separate issue, unrelated to point display modes:

Yes I also confirm Husky's findings with the pixel size issue.

But ... I also want to say a big thank you to Robert S for spending the time and creating these additional Point styles. For me personally I use points a lot when drawing in QCAD, I use them for construction reference and have been wanting some additional point styles for some time now, what Robert s has provided is more than I would have expected and am I very grateful for this :D .

If I try to set a mode and size in Application preferences, it has not effect on the displayed point, I only get it via Drawing preferences... e_confused

Hi J-J
Yes I have noticed the same thing, I will only use these point style options individually per drawing anyway, so for me its no big deal, but you are right to point it out (excuse the 'point' pun), I guess a few tweaks are needed here and there.
I suppose we should raise a couple of bug reports for these things!

Hi everyone,

Point display size:
A value of zero sets the point display to 20% of the viewport height (in pixels).
A negative value sets the size to a percentage of the vieweport height (in pixels). So -25 will set the size to 25% of the viewport height.
A positive value will set the size to the value in pixels. So 25 sets the size to 25 pixels, irrespective of the viewport height.

Only the two shapes (the plus and the X) use the full size. The circle, square and vertical bar are scaled to 80% of the full size. This is because the plus and X extend beyond the circle and square.

The size hasa no effect on modes 0 and 1.

Each drawing has it's own point display settings, therefore setting the Application preferences only applies to new drawings, and not to the current drawing, which is why you need to use Drawing preference to alter the current drawing.

Hope this explains what is happening.

Robert S.
