How can you change part units using parameters or pro/program?

[mhenry]

We have a part that can be in either millimeters or inches. I would like to use the same file and toggle the part units using a parameter. How can this be done?

Mike, this can be done in J-Link by setting up a Model Program.
From the J-Link APIWizard:
A model program is a J-Link program specific to a particular solid model,
that is part or assembly. Pro/ENGINEER activates the start method for a
program when it loads the part into memory and activates the stop method
when it erases the part from memory.

J-Link has the model method SetPrincipalUnits which seems to do what you
are asking for.

Bjarne

We are running wf2; the “SetPrincipalUnits” seems to be a new wf4 command.This dose sounds promising; could you give more details as to when the use changes the parameter form inches to mm the jlink program know to change the unit to metric?

Mike,
you will have to program the logic into the J-Link programs start method.
How to do this will depend on you use case. It could be a simple question
on the command line or a dialogbox. Maybe some automation looking at units
on the assembly where the part is used.
When the logic has decided the units, call the SetPrincipalUnits with the
appropriate parameters.

See the "Solid > Solid Units" section and the "Setting Up J-Link > Setting
Up a Synchronous J-Link Program > Setting Up a Model Program" in the WF4
J-Link APIWizard for full details.
