[solved] Dimension from mm into feet/inches

[Rantanplan7]

Hi everyone,

looks like a simple task, but it isn't. I believe that I still make something wrong.
Mainly I'm working in mm, but sometimes I need a drawing in feet-inches. So I start drawing in mm and want to change the dimension value to feet inches.
I'm always ending up in a mess.
In the attachment there is a drawing. Maybe someone can tell me what I have to do to get the feet inches values - at the moment I would calculate that and would write it in the property editor as label.

You can use
Edit > Convert Drawing Unit

You might also want to adjust the label format under:
Edit > Drawing Preferences > Dimension > Dimension Settings > Label Format > Linear Dimensions > Format

change the dimension value to feet mm.

Typo?

Okay, I can convert from mm into feet but I want feet-inches.
If I convert from mm into feet and than try to change the drawing preferences from decimal to engineering QCAD tells me that I have to go to inches.

Yes CVH that was a typo.... it should be feet inches.

To display feet / inches, you'll have to work in Inches (that's enforced by the DXF/DWG standard).

That's weird, I cannot reproduce my problems.
However, I have some ideas - first of all it looks like QCAD doesn't like changes forth and back in that area and next is that it is important to do it in the right order.
It works well if

1- Converting mm to inches
2- Changing Decimal to Engineering in the Drawing preferences

To go back

1. Changing Engineering to Decimal in the Drawing preferences
2. Converting inches to mm

If I start with converting inches to mm and than to change from engineering to decimal I get weird values.
Also it might be that I have not being patient enough with the convert button and might have clicked it twice....

However, works well now. To ensure that it is ok I will play around with it in different drawings.
