Hi pior, yes this behavior for dimensions is controlled by the "Scaling" property which you can change by selecting the dimension and clicking the "Details..." button to bring up the detailed object properties dialog:





If you want to change the default behavior for new dims, you can change the value of the property preset in Options dialog > Dimensions > "Scaling".

If you have a relatively small number of dims then the "fixed size on screen" can be easiest because the text will stay the same point size everywhere including in PDF output. So you can just set it to be a 12 point font for example and you'll get 12 point text size in your PDF without any extra work needed.


However, that doesn't work very well if you have a larger number of dims and if they are arranged inside of geometry like some lines making a title block table for example. So if you set "Scaling: By model units" the text will behave like geometry and it will be affected by the view's zoom level.

When dims are imported from DXF they will use the "By model units" type scaling because AutoCAD does not have the concept of "fixed size on screen/page" type text behavior.


> 2 - Also, on the same topic : is there a way to convert dims (of either of the kind mentioned above) and

You could try exporting out to PDF/AI/SVG format and then importing it back in.
