Function within constain offests

[povi2946]

Hi,
I would like to request for a feature.
When making planeCoincident constrains I am allowed to set an offset. But I am not allowed to set a formula or use numbers from a spreadsheet.
Also, I usually work in metric but sometimes I need to use inches so I just write 4in or so and it automatically converts within when using other workbenches but in this offset field I am not allowed to enter other system units.. which would be nice.
Thank you

It's worse. If you enter a non-metric unit offset (like 11+1/2") in the properties, and then you edit the constraints, the offset field containt invalid data.

The property:

The constraint edit:

I think this issue is about supporting units properly:

• being able to enter units in the constraint editor
• honouring the global unit settings and parse them properly with the constraint editor.

Here is my settings for units in FreeCAD to help reproduce

@kbwbe do you have any time to look at this?

The code in commit 5fda4cd is part of the problem.

From the example above,
user_qty is 1112.0 and user_unit is +/" which lead to setting the suffix on the QDoubleSpinbBox the second time to +/"

I have a partial patch that show the proper mm value.

But I think instead of using QDoubleSpinBox, it should use one of the FreeCAD SpinBox. Another problem is that typing something does trigger the solver...
