HI,
In AFX,Connectors and Equipment use lots of udfs for design,this is nice for design the similar fetures .
There are three files about udfs in part mode,
1. D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\connectors\steel_construction_mm\no_standard\beam_end_cope.tab
D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\udfs\beam_end_cope.gph
2 D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\connectors\steel_construction_mm\no_standard\beam_end_cutout.tab
D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\udfs\beam_end_cutout.gph
3 D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\connectors\steel_construction_mm\no_standard\pipe_squash.tab
D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\udfs\pipe_squash_cyl_ref.gph
We can very well use three udfs for design and modify variable dimensions via menu of "modify connectors element" ，
Variable size value can be updated automatically.
If I define udf for design , for example ， I set up a cylindrical feature of udf , and then join this udf name to the sel file.
……………
2_winkel asm_copy
beam_end_cutout udf
beam_end_cope udf
pipe_squash udf
z_zhu udf
dir_up dir
sure set up the load files
D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\connectors\steel_construction_mm\no_standard\z_zhu.tab
Z_ZHU.TAB：

END_GUI_DESCR
D:\Program Files\PTC\Creo 3.0\M040\Common Files\afx\parts\udfs\z_zhu.gph
Then, we can use this udf loading into part file in afx, but if we modify this udf via menu of "modify connectors element" ，
The message bar prompt "No components selected by automatic intersection",
Variable size value cannot be updated automatically
WHAT HAPPEN ?
