It sounds like you may be confusing a union with a re-use. I believe Reuse is a higher end option; it shows up as "Physical Design Reuse' checked in your <Help><Installed Options...> dialog if you have the option.
"Unions are user-created part associations that have a strict relationship with each other, such as distance, rotation angle, top, or bottom side. A common example is placing a filter capacitor to reside on top of an IC. When a selected union is moved or placed, the physical relationship between the parts, or union members, remains unchanged."
"A physical design reuse contains a collection of items, called elements. You can manipulate this collection as one item. Physical design reuse elements include: components, routes, vias, and text items. Properties and attributes of these objects, such as test point status, are included in the physical design reuse."
Or did I completely miss what you are trying to do?
Thank you for your reply.
I am aware of physical design reuse and I have tried it in other designs,
If you follow the below link you will understand what I am trying to ask you for.
will I be able to use with out the interCAD program which is a software used in that video. One of the guy told me.
I want to place the components like how it's been done in that video. Will that be possible with create like union command ?
And why can't i able to add images with this post ?
I figured out how to do it by myself.
The components which are not associated I protected them and so when I do "create like union" only the unprotected items are dispersed grouped.
But i could not able to see design reuse and matched length in my PADS.
Do I need to buy a higher version to use it ?
Probably. My ES license has it. I'm not sure where the options start. You'll need to talk to your sales rep.
