reference surface

[ptc-210291]

I am using Creo Parametric Release 6.0 and Datecode6.0.4.0

1. When using a surface from an another model, when you copy and special paste through the assembly
You can paste that surface into your model, how can you keep the model you're working on and the model you copied the surface from referring back to that surface that you just pasted in to use as references for a new part. if you right click on it and say exclude or permanently delete all references the model that you created from that surface still goes back and looks for that surface and gives you errors. how do you keep your new copy and special pasted surface from ever being referred to?

2. also when you set the directory to the file folders you're working in it won't stay connected to that directory it always goes back to the default


Here are the errors that I faced

For (1), I'd say the easiest is probably to open the part, select the copy feature and then use the "collapse" function to turn it into static geometry:

To provide some context to the solution offered by @pausob , see this link.

Another option is to use an external copy geometry (not paste special in the context of an assembly) and set it to be independent.  The advantage here is that you have the option to reestablish dependency going forward if it is needed.

To build on @tbraxton suggestion of using external copy geoms -

if extern copy geom is set to be completely independent (no dependency) then the link to the original is severed and cannot be re-established.

If set to be "manually updated", it will not auto-update if original changes - but the dependency remains.

IMO, if you are going to use the "no dependency" option then the copy + collapse method is just faster.

I find one good way of collecting the geometry from multiple places in the assembly, which I want to turn into static reference in a new model - is to use the "Shrinkwrap by manual collection" method, as showcased in this video:

(I think you have to have advanced assembly license for this)

I then collapse the external copy geom feature that the tool made in the new model and go from there...

ECG features set to no dependency can have external dependencies restored. It is not officially supported but there is a hidden config option that allows for dependencies to be restored. This is not officially supported by PTC so if you do not know what you are doing don't mess with it, but I can confirm that dependencies can be restored when set to no dependency.

I didn't know this! Cool tip!
