Master Geometry (Skeleteton Model)

[yusf]

Dear Users

Since i am new to PTC Pro E i am having some diffuculties in PRO_E 2.0 environment such as taking referance from the master geometry. i would like to explain what my problem is :
Step.1)
firstly i am creating a master geometry that includes ONLY planes,datums,points etc.

Step.2)
And then trying to create first geometry by taking referance from those planes etc.this is clear.

Step.3)

then opening new part and trying to create second part that is mated i.e with first part.NOW i need to take referance from previous geometry so that my second part is to be created in the proper orientation and assembled correctly.I searched the related problem and understood that INSERT/Shared Data /.... link is the solution path and i followed that by selecting INSERT/Shared Data /Copy From Other Geometry and selected edge of first part i.e i have seen that whole geometry is referanced and when i tried to assemble these two part i got 3 geometry one that first,one that second plus the first parts' copy..this not what i want also where am i wrong at this step or can anyone tell me the right way for creating skeleton master geometry and then taking referance from them?..

I will look forward to hearing from you.

yusf,

Setting up a skeleton part is by far the best way to contol the geometry of related/multiple parts so you're doing the right thing there.

To reference the skeleton from other parts the best way is to use Publish Geometry and Copy Geometry features.

Start by having an assembly that contains all the parts you want to share references between. The best way to assemble these in is to use the standard co-ord systems in the part (or default position).

The Publish Geom is created in the skeleton and is simply a way of grouping together the references that you want to send to another part. Go to Insert>Shared Data> Publish Geometry.

The Copy Geoms go in the parts and pick up the data from the Publish Geom, via the assembly. To create them, go to the assembly window, activate the part (right click>activate) then go to Insert>Shared Data>Copy Geometry. In the feature create window, select Publish Geoms>Define then pick the Publish Geom in the skeleton (easiest done via the model tree).

The data selected by the Publish Geom (in the skeleton) will now appear in the part. You can add or remove references by editing the Publish Geom. Once you've modified a publish geom you must regenerate the appropriate part to update it with the changes (the assembly the copygeoms were created in must be in session to do this).

NOTE: You don't strictly need to use a Publish Geom, as the Copy Geoms allow you to pick individual features, but the Publish Geoms are a good way to group references together and understand what is being referenced by other parts, especially if the skeleton is being referenced by multiple parts.

Also, don't be tempted to reference the skeleton directly by creating features in parts via the assembly window (working with the part activated in the assembly). This can result in very messy references that are difficult to trace afterwards.

Hope this helps.
