External Copy Geometry

Back      Next


The External Copy Geometry (ECG) functionality copies geometry from model to model without copying the geometry in the context of the assembly. Dependency on the assembly and all models along the path between the two components is avoided.

In this chapter we will see the differences between Internal Copy Geometry Feature and External Copy Geometry. We will also learn different methods of creating ECG feature.




The topics covered are as follows.

  • The basic difference between a Copy Geometry and External Copy Geometry Feature.
  • Converting an Internal Copy Geometry feature to External Copy Geometry


Assembly of Components


The topics covered are as follows.

  • Creating an External Copy Geometry feature in  part mode
  • What models should be in memory to regenerate a Copy Geometry and External Copy Geometry Feature
  • Determining the dependency on parts and assemblies along the path between a source and target component
 Assembly of Components


The topics covered are as follows.

  • How to create a reference pattern in a component by referencing a pattern in the skeleton model.

"We purchased both of the tutorials about a month ago, and I have to say I was skeptical because they were considerably less expensive compared to the other available tutorials that I found.  We had one of our CNC programmers and our lead mold designer evaluate them before we used these to train two new employees.  Both engineers had very good things to say about the tutorials.  Each said they learned or remembered things they hadn't used in a while and that the time they spent going through these was well spent.  I have to admit I can't wait for this company to produce some more generic tutorials on modeling, assembly, surfacing, etc.  In my opinion these tutorials represent a good value.  I hope they're able to continue to produce good material and keep their prices in check."
