Issue with step file export

Hello

Tool version :17.2-2016 S063

When I export step file ,outer layer (Coverlay) thickness is not added to step file (Refer first image) .Showing wrong PCB thickness (0.28mm) on stepfile.

As a workaround i removed outerlayers from cross section and added its height to mid layer (as shown in image2) then I got proper thickness on step file .

Anything I am missing here ?. Please suggest ?

Thanks

Try adding the layer correctly - rather than as a manually as a dielectric, so right click above TOP and Add Layers then add the Coverlay_Top above. Take a look at www.youtube.com/watch about 3.50 shows you this.

You may need to confirm this with Cadence Online support but I think the issue is because Coverlay is a Rigid Flex class and the board you have sent is a standard stackup. If you create a Flexi section (zones) on your board then the coverlay does show up. You do have to draw this on rigid flex / coverlay_top layer for it to be shown though.
