Hello everybody 
I'd like to know if anyone has ever tried to create in Catia V5-6R2024 a tool like the one in the attached images. 

This tool is from ISCAR catalog and represents a kind of "conical/barrel" tool. The 12° angle makes a difference in the following. 

In V5 I tried to define it using the "barrel" family but I cannot correctly define the cutting length Lc which appears to be linked to Rc=1.5mm, Da=8mm and Db =8mm resulting in a Lc=21.153mm that cannot be modified to comply to ISCAR specification Lc=14.1mm for that tool. The 12° flank/conical  angle cannot be set in this family of tools.
The image below on the left is the V5 definition of the tool, the one on the right is the one from ISCAR online catalog.

I also tried to compare the geometries of the two tools:
- the purple transparent one is the ISCAR step file downloaded by the manufacturer site
- the yellow one is the one created in V5 by the "Geometry Creation" command.

The overlapped models show  the difference in the flank profile of the two tools resulting in approximately 0.8mm max discrepancy along the diameter. 

When using it in a "Z-Level" operation with "3to5X converter" option active the computed toolpath and the analysis of residual material will be not correct. 

Is there a way to define such a tool in order to have geometrical specifications identical to ISCAR ones? 
Not being possible to set the cutting length Lc to the exact value appears to be the main limitation which I suppose is a constraint required by barrel tool family, but that 12° angle make it a different tool I suppose.
