Replace component when opening a assembly template file

[st3v3]

I’m new to ilogic and looking for some help

I have an assembly with a number of ilogic rules that i intend to use as a template file, the assembly consists of 1 main part (knife.ipt) and a number of additional parts (lugs.ipt)

I have used Component.Replace to allow me to change the lugs as required.

 What i would like is the option to replace the Knife when i open the assembly template file,

Preferably with the option to either browse to the require file of type in the required file name

Any help on this would be great
