Hi,

І was creating the midsurfaces from solids in Femap 11.3.1 using *Offset Tangent Surface *command.

And at some point new surfaces are being created much bigger. I've measured the scale factor. It's 39.37 like scaling into inches. But in Geometry tab in Preferences solid Geometry scale factor is 1.

How can I solve this?

Dear Oleg,

This is the eternal problem we have in FEMAP when dealing with units, mixing in the same database inches with meters or millimeters, the result is a disaster. The reason of the error is because your 3-D Solid CAD geometry has been imported initially with different **SCALE FACTOR** as the one you use now, surely INCHES (SCALE FACTOR=39.37) was used, then you have a model containing geometry in more than one scale factor. Simply LIST ALL your solids and take a look to the **SCALE FACTOR**, in my case that use millimeters ALL solids are with SCALE=1000

List Solids 1 Solid(s) Selected... Solid 1 - Sliced Body Address: 406352Scale: 1000.

You have a few options:

- Import the geometry again, this way the correct scale factor will be used.
- Or use command
**GEOMETRY > SOLID > CLEANUP**and make sure to activate**MATCH MODEL SCALE FACTOR**, this way the command will adjust the internal scale factor of each piece of selected geometry to match the Solid Geometry Scale Factor that is currently set in**File, Preferences**on the**Geometry/Model tab**

Best regards,

Blas.
