Question Autocad

HI all, I don't know sometime I take drawing from my customer, I export a dxf and I import in solidworks but sometime de units change the drawings was in metric but solidwork put in inchand drawing is really metric and when a importg to mastercam it's ok . Why ???

Could it be that's what "insertion units" are specified?

Solidwork takes insertion units from autocad.

Solidwork takes insertion units from autocad.

So there's no problem then right?

Where can I change the insertion units in autocad if the drawings was in metric

I'm confused. If the dxf file was made from an AutoCAD dwg file that was done in metric in the first place and Solidworks changes it to imperial upon insertion then it is a Solidworks problem and not an AutoCAD problem. Why is it an AutoCAD problem?

Is it possible because my drawing is unitless ???

Do you know for a fact that the original drawing was done in metric units or did you just assume that it was?

I talk to the customer and I said it was draw with unitless. But all ove my drawing was in unitless and it's works.

It must be my audible receptors but I did not understand a word of what you just said.

When you import a dxf file into Solidworks what options are available to you?
