Hi,
here are a few information.
- If you use the IFX-option 'USE_EXTERNAL_REFERENCES' set to 'NO', it is not possible to reference on a point or axis pattern for IFX fastener creation.
- In this case you can assemble in the selected single instance, or you can assemble the fastener on all instances of a pattern
- If a feature has more then one point or axis, you can also assemble the fastener on all instances of this pattern
- The assembled fasteners are summed up to a group - after creation you only can modify the fastener, but not the count of elements
So to answer your question in short - it is not possible to bring up this dialog after fastener creation.
This is only possible if you use external references. Then you can change between pattern fastener and assemble single instance while edit.
If you need more information, please attach your '.<ifx>\configuration\ifx_options.xml' file and more information about the selected position reference for the IFX fastener.
Thanks.
