[solved] QCad changed a dimension figure unasked

[Krischu]

I had a drawing (imported DXF) and added some dimensions. The I selected the whole artwork, copied it and pasted into a newly opened drawing.

Suddenly a measure had changed from 18 (mm) to 17.6918.

Does Qcad recalculate dimensions on its own? In another thread (Community Edition) I remarked on that (Qcad changing measures)
and Husky said that it never occured to him. I can prove the opposite, many times.

Question: If you use the "Paste" tool what is the chosen scale in the option bar?

It looks like you are still a step ahead of me ...
Can you post an example drawing for us so that we can try to reproduce that behavior?

In the Source Window (TAB) Scale is 1:1. Before pasting into the target Window, there is no Scale in the option bar. After paste there is
Scale[1].

Attached is the drawing. Open it and open a second new empty drawing. Select all (CTRL-A) and drog it over to the empty drawing. Then paste is. as soon as it appears hanging at the cursor, you can alrteady see the meaures having changes to some fractional values.

Thank you for the example drawing. Now we are talking ....

Your source file has a precision setting of 0. That rounds the dims:

Your target drawing has not a precision setting of 0 - that doesn't rounds the dims (or not enough).

Solution: Chose the same settings in the source and in the target drawing what will make sure you will see the same thing for dims in both drawing ...

I would like to thank you for the detailed reply. Keep in mind, that, if I do not reply, it implies "many thanks, thanks a lot etc.". Scaffolding the forum with "thank yous" wouldn't be welcome, either, would it?
