Measuring distance after copy or rotation etc.

Postby Joern » Mon Jul 30, 2012 10:53 am

Hallo,
i am a bloody beginner and therefore my question will sound trivial:

After copying or rotating or moving etc. an object I cannot perform exact distance measurements e.g. between circle and center. When measuring in the original drawing the programme will show "referenz" for the center. In the copy it will show "raster" and that will result in any odd but not correct values.

What do I do wrong when copying etc.?

Thank you for help.
Kind regards

Hi Clive,
thanks for your speedy reaction.

It is a new drawing in QCAD and I copy the circle into the same current drawing in order to duplicate an object.
I save it as *.dxf and my OS is W7 64 bit.
Now that you asked, it appears to me that the trouble starts after saving because I controlled the the distances after drawing. At that time they were o.k.
When I open a saved drawing, the measuring procedure will be as described in my mail, but funnily enough not in all cases.
Can't imagine it's QCAD, it must be me.

Regards and thanks

Hallo Clive,
I'm working with the same default drawing units throughout all old/new drawings.
Raster does not appear in command line ( N.B. I got an installation with german language!)
I'd like to mail you two files with simple drawings, one where you can measure as one should, the other where it doesn't work.

But I don't know how???

Regards

Hallo Clive,
thank you again for your prompt answers. I really do appriciate that.

The radii in the drawings are: 528,9 mm (small radius), 643,5 mm (big radius).

Looking forward to your findings.

Regards

Hallo Clive,
thank you for all your bother. Unfortunately I could not verify your findings.
To show you what I mean, I will send two printscreens, one (sample 1) where it says "raster" and where you are unable to hit the centre of the circle segment exactly and the other (sample 2) where it says "referenz" and where you are able to hit the centre of circle and measure correctly.
Has all this to do with the snapping ("fang") function? I tried with and without - same result. But as far as I got to know QCAD by now (which is rather little!) it should do the right thing automatically.
Regards and thanks.
