About Building 3D/2D Thumbnails

This page describes features and considerations about building 3D and 2D Thumbnails.

This page discusses:

Recommendations

  • Test that the 3D Dynamic Thumbnail option performs efficiently. To activate the option, see 3D Navigation settings. To test the option, open a product structure, and do an explore and a collapse.
  • Index your content before running the Thumbnail Builder. For more information, see Installation and Administration: 3DEXPERIENCE Platform - Installation: Installing 3D Indexing Server
    Tip: If a product structure is indexed, in interactive mode, you can see the following message in the Search box: "Ready for 3D Search".
  • After a modification of the geometry, the Thumbnails and the index might be incoherent until the next indexation. Launch the indexation as often as possible, and use Dynamic mode to generate Thumbnails.

Generation of Thumbnails

Thumbnails and Security

To create and delete 2D and 3D Thumbnails, you must have a security level that is at least equivalent to the security level of the creator of the given object.

Thumbnails are more secure when generated in Dynamic mode than when generated in Static mode (that is, using the Thumbnail Builder).

Thumbnails generated on structures are not secure. The permissions for these thumbnails are granted to the user who generated them. They are not based on the permissions granted for the different objects of the structure.

Generation of 3D Thumbnails

The options available to generate 3D Thumbnails vary depending on your content source connector. The options that are not available for the content source connector in use are grayed out.

When creating 3D Thumbnails, some surface colors in the original part might not appear in the final 3D Thumbnail because of representation simplification.

When you use the Very High accuracy option, 3D Thumbnails are generated from raw CGR and no representation simplification is applied.

For a 3D XML connector, you can only generate 3D Thumbnails once.

Generation of 2D Thumbnails

2D Thumbnails are computed only if the corresponding 3D Thumbnails are computed.

2D Thumbnails for a reference are only available by default if the reference has only one child representation. This way, the thumbnail of the reference is the same as the representation under it, which is already computed. For more information, see Installation and Setup: Install: 3DEXPERIENCE Platform: Installing 3DEXPERIENCE Platform Services for the First Time: Installing Services One-by-One: 3DSpace: 3DSpace Index: Building Thumbnails and Simplified CGR.

If the reference has several children, the thumbnail is not computed, because it is impossible to choose one between several. For example, a part "Door” has two representations, one for the closed door and another one for the opened door. The thumbnail is not generated because there is no way to know which one to use (opened or closed door).

Other Considerations

2D and 3D Thumbnails are no longer generated in the same repository as representations, making lifecycle operations more robust. As a consequence, thumbnails are no longer stored in content export content streams, and you must regenerate Thumbnails on the export target machine.

When computing static Thumbnails for references, the final Thumbnail might not contain all the occurrences, especially for large structures. Thumbnails provide an overview of the structure, but do not necessarily contain all the occurrences to keep them lightweight.

The Thumbnail Builder does not support position matrix overloading. Therefore, some 2D and 3D Thumbnails might have incorrect positioning.

Managed Batch Process Errors

This section provides the list of errors that might occur when you run the Thumbnail generation.

Domain Errors
101X - Errors related to representation simplification
  • 1011 Dynamic UV representation is not supported.
  • 1012 Representation without triangle for simplification.
  • 1013 Impossible simplification.
  • 1014 The representation bounding box is corrupted. It is too big.
  • 1015 No representation by inheritance (children have of the a 3D representation).
11XX - Errors related to save 3D and 2D Thumbnails
  • 1111 Impossible to save the Thumbnail.
  • 1112 Impossible to save as Jpeg.
  • 1113 Impossible to open the PLM engine.
  • 1114 Impossible to locally save the 3D Thumbnail.
  • 1115 Impossible to delete the representation instance of Thumbnail (verify its security policy).
  • 1116 Impossible to delete the representation of Thumbnail (verify its security policy).
  • 1121 No 3D Thumbnail to save (during global save).
  • 1122 A problem occurs during the complete save (during a global save).
121X - Errors related to the format used to save 3D/2D Thumbnails
  • 1211 Nonappropriate format to be derived in Thumbnail.
  • 1212 No description is attached to the representation reference (you need a CGR or an UVR file for Thumbnail construction).
  • 1213 CATPart is existing without authoring Visu.
  • 1214 A reference content (.content) exists without authoring Visu.
  • 1215 A Thumbnail description cannot be removed for this reference (you have probably changed the option "Ignore intermediate nodes" for a subsequent computation of the 3D Thumbnail for this node).
  • 1216 Unknown format to be derived in Thumbnail.
  • 1217 Reference without representation and without instance.
  • 1218 Generate Thumbnail with index produces an empty representation.
  • 2011 No Thumbnail computed on this node.
