Thanks you very much for your help. it is working.I have a question ,
Is it possible to link one part file dimension to another part file?
1. Part first is a cylinder in parametric table i changed it,s name OD , ID and thk. ( find attachment )
Cylinder ID is ( ID=105)
2. Then i made 2 nd part whose step od ( od=102) is going to insert in to cylinder id.There is 3 mm clerance every time
3. so i have to make equction in 2 nd part that ( Step OD= ( ID-3).
means next time when i will change ID of cylinder OD of 2 nd part will ger changed automatically minus by 3 mm than id of cylinder.
You should use the function "Link" in the "parameters" and choose *.ipt. & .*iam file format. Then, When you modify the master part, you just have to open and update the slave part.
If you don't want to open your part to make the update you should use ilogic rules. try the plugin "Link parameters" who generate the ilogic code.
