ECAD Import question

I am exporting idx files from Allegro and when I import into Creo 3 I am losing the decimal after two In other words what shows in Allegro as 0.12345 shows up in the Creo Model as 0.12

I am sure this wasn't happening in Creo 2.

I noticed it when looking at connectors the holes were not concentric with the posts. The connector is placed correctly - out to 5 decimal places in the assembly but the pcb file the holes are truncated to 2 decimal places.

Any thoughts?

Hi Bill,

It might be due to default decimal places in Creo, Default value for decimal places is 2 in Creo, you may try changing that to 5 and test the import. Config option is default_dec_palces

Bill,

I just got a support ticket on a related topic last week from PTC, and they suggested looking at the parameter ecad_import_relative_accuracy.  This was in CREO 2.0, but it may be there in 3.0 as well.  Try setting that parameter to to how accurate you want your design.  They stated that in CREO 2.0, thee is a warning in the import log file (ecad_in.log_x) that suggests what values you need.  If this particular warning is not in that log file, maybe there's something else in the log file that will lead you to the correct solution.
