Wrong exporting from Autocad to Inventor? or ???

[Eugene777]

Hi there, i have some difficulties in Inventor .

I have file in .mm ,when i open it in  Autocad , it display correct dimensions , in .mm (for example one dimension is 80mm) , but if i open the same file in Inventor, the same dimension ( 80mm) display 80inch.

What wrong with it?

PS. I have made Tools - Documents Settings - Units -mm  and it doesnt help

Will you be able to share the file so I can have a look?

No, it is 80 inches in AutoCAD, not 80mm.

Open your dwg file in AutoCAD

run the -dwgunits command (with the minus sign)

What does AutoCAD say the units are?

Hi Eugene777,

It's not clear to me what you have tried so far, but I think these steps should work for you:

1) In AutoCAD select the L profile and then right click and choose Copy (or press CTRL + C on the keyboard)

2) Next, switch to Inventor and make sure you have a new part file created and a sketch active for editing.

3) Then right click in the sketch area and choose Paste (or press CTRL + V)

4) Next, right click and choose Paste Options.

5) In the Paste Options dialog box, choose the Specify Units option and set the drop down box to the correct unit, then click the OK button.

6) Then, click in the sketch area to place the pasted geometry.

Note too that you would be well advised to create a Sketch Block from your pasted geometry.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

They use inches - they just don't know it.

AutoCAD was known as a "unitless" program - users called "1" whatever unit they wanted.

As you see now, units are now stored in the file.

You can convert AutoCAD (follow command line with -dwgunits command) or in Inventor.
