When trying to edit a legacy sketch in NX which supports New Sketch algorithm, "Edit Legacy Sketch" dialogue pops up. After that, if selecting "Renew and Edit" in the pop-up dialogue, an extra CSYS is generated.
Reproduced Steps:
1. Open a new part in NX10 or before. Please use Model template as the template part. 2. Create Datum CSYS newly.( Please select "Selected CSYS" as "Reference CSYS.)
==CSYS by "Selected CSYS" as "Reference CSYS==
==Newly created CSYS== 3. Create one more CSYS on XY plane of the existing CSYS to be created in Step.2 above. (Please toggle "Create Intermediate Datum CSYS" OFF at that time.) and save the part 4. Start NX1953 or later 5. Double click on a sketch feature in PNT and select "Renew and Edit" in an appeared dialogue.
==creating an Extra CSYS newly==
Solution
The behavior is working as expected.
Notes and References
On Renew command we decided to make the datums external because the new sketch does not support "Make Datums External" and "Make Datums Internal". We do this to clean up the data structure without losing any information.
Internal CSYS of the sketch which is created by turning "Create Intermediate Datum CSYS" OFF is displayed in PNT by executing "Make Datum External".(For e.g, the operation in NX9 is as follows.) Also, the behavior that makes CSYS internal can be created in NX10 or before, but it has removed since NX11. Therefore, the behavior occurs only for the data to be created by NX10 or before.
Also, the legacy sketch to be created by an option "Create Intermediate Datum CSYS" in "Reproduced Steps.2" above never creates an extra CSYS newly with Renew because the system considers it unnecessary and removes the internal CSYS automatically.
