Which filtering for base-system elements and other references

[[Ka...]]

Dear colleagues,
I no longer know which filter to use for ISO GPS with which type of geometry, so I´m lost in ISO GPS jungle. 😞

So far we have used [G], i.e. Gauss for all geometries in the base system. Whether cylinder, plane, circle, cone...
The reference formation is set to default in CALYPSO, i.e. NOT to Iso5459.

We now want to convert to ISO5459, which is possible in our version CALYPSO 7.4.24 in conjunction with [CE] Tscherbyschef.
However, this should only affect normal references and not the references in the base system ?? ( Why )

In ISO5459 I now read that a filter is ONLY specified for surfaces. This should first be [EM] (morphological closing ball)  and then [GE] (Gauss from material free side).

So my question:
1) How to implement [EM] and then [GE] in our CALYPSO 7.4.24
2) Is this filter combination even implemented in the latest CALYPSO version?
3) What about filters for geometry like cylinder, circle, plan

Thanks a lot for your support 🙂

Best Regards
Karsten

P.S. Sorry, I need to use a translator for that it might be that something is written a little bit strange...
