Datum Curve by Equation and Parameters

[MNMcAllister]

I'm new to Creo, but used Pro/E back in Ver. 20 and some WF releases.


I have a defined model PARameter and would like to use it as an end value for the variable 't' when creating a Datum Curve by Equation.


Before I would set the range with 0<=t<=PAR, which worked.


In Creo there are start (SV)and end (EV)values defined, but how can I ensure the endvalue will always equal my model PAR?


There aren't dimensions associated with the SV and EV, so how would I need to set up the relation?





Any help appreciated,


THX

Let me carify.


What is the syntax for aRelationto setthe value of a Parameter of a Feature to a Model Parameter.


I can find the Feature ID and the desiredFeature Parameter ID , but I don't know how to relate this to the Model Parameter.


TIA

leme ask Tad one of the design engine instructors. he will know.

Thanks.


I hope there is a way.

It seems mcadCentral or moeZilla didn't cache the text I typed.

Good thing I always expect the least from people/sites I deal with & copied my response prior to posting. The Admins or their Scripts are actively chasing the Bots&Spamers. After I was auto labeled as a spammer yesterday.

-------------------------------------------------------
The Syntax should be something along the lines of


EV = &Parameter_Name:fid_####

Where #### can be FeatureName or FeatureID


Feature id never changes and I think for ProE/Creo/NextProd this will be the syntax.


How's the weather in you Japan these days? My friend Laura who used to live there is back in the states now.


I'm interested to see your finished (relation/equation) you end up with.

I figured it out.


Instead of trying to set the endpoint of the variable, t, to my parameter, I created a relation between the two. Then I used that to drive the 'x' & 'y' equations.





Look in the attached file to see what I mean.


This will creat a parabolic surface from the two variables; focal_length and openning_diameter.
