RELATIONS

[megaladon]

so im trying to make a spring flexible by relation in an assembly i have created the ref dim called rd2 and renamed the dim of the over all spring heigth "SPRING_LENGTH" and wrote this relation


SPRING_LENGTH:11cid_5=rd2


also tried SPRING_LENGTH:11=rd2


11 being the feature # in the assembly


cid_5 being the feature # in the spring part itself


i always end up with this error




errorInvalid symbol 'SPRING_LENGTH:11cid_5' found.


also is there a page of what all these errors mean?

You need to put session id not feature number.


In 2001.
In your assembly,goto relation, Show > Session ID.


This is the number you need to put SPRING_LENGTH:XX


Another way to find session ID is, in assembly select Modify and select a feature in your spring. Dimensions are shown and if you switch to name it will show something like "d23:6", the number after ":" is the session ID number.


Note: this session ID number may change from session to session.


Good luck

thats exactly what i needed thank you so much charleskim



now just have to write the realtion that keeps the same number of coils per length change


what i tried was pitch=SPRING_LENGTH/8


but doesnt update that way in my assembly


seems like this would be the logical equation unless it doesnt recognize it or supercedes it in assembly?

It's nuch easier in WF2, just "make flexible".

 

[megaladon]

that is simpler i just copied my realtion of pitch d2=SPRING_LENGTH/8 into dialog no need for ref dim in assy


thanks DR_G
