Different CAD versions

Hi

 

I am not sure how one can have different CAD file versions.

 

case 1 :

  • Parts of Creo 4.0
  • Assembly of Creo 2.0
  • Drawing of Creo 2.0

In above scenario, I assume that All data were in Creo 2.0. One can update one part and save it onto Creo 4.0 and delete part version saved in Creo 2.0. With all these, Can one open drawing in Creo 2.0? I guess no as one of the part is saved in Creo 4.0 ... But drawing can be opened into Creo 4.0. Is this correct understanding?

 

case 2 : Below scenario is something confusing for me:

  • Parts of Creo 2.0
  • Assembly of Creo 2.0
  • Drawing of Creo 4.0

Here earlier all data must be of Creo 2.0 and then one is trying to save drawing into Creo 4.0. With these saving , alll data i.e. parts and assemblies will also not be saved as Creo 4.0 data?

 

Feel free to ask in case of any confusion.

 

Thanks and Regards

Ketan

1.1: Yes

1.2 and 1.3: The drawing will be saved as Creo 4. Whether or not the parts or assemblies get saved is dependent on the regeneration status of those parts. If nothing is different, they will stay Creo 2. If any of them change as a result of regeneration then they will be saved as Creo 4. Just opening a part or assembly can modify it depending on if it has external references, and or it regeneration state when it was last saved.

 

2.1: Again it depends on the regeneration status of the parts. See above. It could be true that only the assembly gets modified but it could also be true based on the regeneration status that other parts get modified.

 

If this is really a deal killer for your organization should should simply open the assembly in Creo 2 and make the change in Creo 2.

 

Keep in mind that once something has been saved in Creo 4 all parent assemblies, drawings, external references will need to be updated to Creo 4.

Case 1:

  • If you have previous versions of the Creo 4 part you can roll back to the last iteration it was saved in Creo 2 and then continue from there. You can open the .prt files with a text editor (like notepad) and in the header part that is readable it will say what version the part was saved in.
  • Alternatively you can bring everything up to Creo 4 (assembly and drawing)
  • You may also be able to open the Creo 4 part in Creo 2 with the granite plugin. Be aware that the plugin doesn't always work, its a clunky technology and I haven't tested this specific use case so I am not positive it will work. Information about the plugin is here:
    http://support.ptc.com/products/granite/gcri/index.htm

Case 2:

As soon as something is modified in a newer version of the software it "upgrades" the file to that newer version. If in this case the drawing was simply opened and saved then yes it is possible that just the drawing would be upgraded to Creo 4 and not the parts and assemblies. That being said it is usually the case that the referenced part or assembly gets modified when working on a drawing so in this case any modified parts or assemblies  would get upgraded along with the drawing.

    Hi,

     

    case 1 :

    • Parts of Creo 4.0
    • Assembly of Creo 2.0
    • Drawing of Creo 2.0

    Creo 2.0 will not open parts, assembly, drawing

    Creo 4.0 will open parts, assembly, drawing

     

    case 2 : Below scenario is something confusing for me:

    • Parts of Creo 2.0
    • Assembly of Creo 2.0
    • Drawing of Creo 4.0

    Creo 2.0 will open parts, assembly

    Creo 2.0 will not open drawing

    Creo 4.0 will open parts, assembly, drawing

      Thanks to both of you for responding on this. It is a bit clearer to me. 

       

      Below is my conclusion for our own scenarios:

       

      1. All parts, Assembly and drawing were prepared in Creo 2.0. Post that we migrated to Creo 4.0 and modified one part only into Creo 4.0 and there is absolutely nothing (Not even opening of CAD into Creo) done on assembly and drawing. With this : 
        • Case 1.1 : We would be able to directly open drawing into Creo 4.0. Is this correct?
        • Case 1.2 : Before check in to windchill, we need to save drawing opened into Creo 4.0. These would update Creo drawing version as 4.0 along with all associated parts , assemblies and sub assemblies. Is this correct?
        • Case 1.3 : Before check in to windchill, we need to save drawing opened into Creo 4.0. These would update only Creo drawing version to 4.0 . Rest all parts (except one which was saved in Creo 4.0) and assemblies would be of version Creo 2.0 only. Is this correct?
      2. All parts, Assembly and drawing were prepared in Creo 2.0. Post that we migrated to Creo 4.0 and need to modify one parameter only for an assembly into Creo 4.0 and there is absolutely nothing (Not even opening of CAD into Creo) done on assembly and drawing. With this : 
        • Case 2.1 : When we will open assembly into Creo 4.0 and save it, all other sub assemblies and parts would remain of the version 2.0 only. Is this correct?

      Thank you so much again for your valuable thoughts on this.

       

      Regards

      Hi,

      • answer to Case 1.1 ... Yes
      • all other Cases ... for me it is difficult to guess what is going on on your site ... suggestion: create test data and verify all situations by yourself
