Insert/Datum/Evaluate. You must have allow_anotomic_features set to Yes in config.pro to use the Evaluate feature. Steps: Give the feature a name. We will call it ARC1. Choose Create. Give the measurement a name. We will call it ARC1. Choose Edg/Crv Len, which is the measurement we want. Choose the arc. We can now use the measurement in a relationship or parameter:
parameter: arc1
relationship: ARC1=ARC1:FID_ARC1
The parameter ARC1 now equals the evaluate feature ARC1's measurement.
I'm having a bit of trouble with my Datum Evaluate feature- more specifically, I'm having trouble with features updating based on relations created with the Eval feature.
here is the senario,
I have two points in space, I have created some surface geometry around one of the points and would like to transform it from one point tothe other so I created a curve between the two andcreated a datum plane nornal to the curve
I then did a Datum eval feature to measure the curve length. (called length)
Ithen did a copy and paste special of the quiltand transformed the quilt using the plane as a direction and added the relation
move=length:FID_LENGTH
d145=move
and presto - it updated .. but..
then I move one of the points, the evaluate feature updates, the move cannot be reddefined (value greyed out) and regenerating the model doesnot update the move..
but if I regenerate the model againit works..
is this a bug?
I have done a simple test to see if feature relations are working and they are.
