I have an issue with the working planes in Creo 7.
The planes can only be shown when Plane Display is activated. If assembly contains a large number of parts, planes of all parts is being visible when the Plane Display is activated. I just want to highlight only one plane of the part in the assembly. It doesn't look to be possible. When I go to the part in assembly Model Tree and toggle visibilty of the plane, nothing happens, i.e the plane is still invisible.
Do we have a solution here?
This is what layers are used for. If all the plane features for each part and assembly are on layers in their respective files, you can hide all of the layers and unhide only the layers you want or an individual plane.
Here is a sample in 7.0 with layers and layer rules. You can use the layer tree to show datum layers for the assembly or a single part. Individual features can be shown from the model tree or the layer tree. Hopefully most of the parts and assemblies already have layers in use. Otherwise it is a bit of a long process to create and populate all of the layers for each model. Layer propagation and mapkeys can speed up the process. It is mush easier to have layers with rules in your start files.
Checkout the PTC Creo help on layers to learm more about it.
The search tool supports the selection of a part datum plane when in assembly mode. The planes do not have to be visible to select them when using the search tool.
Use of layers is advisable as explained by @kdirth . This will enable you to filter the display of datums.
Develop or copy a layering scheme that will allow you to control datum features. This is an example of layers for datums defined in a start part. You can create layer rules that will automate the collection and assignment of features to layers when they are created.
Creo is highly customizable but requires a large investment to configure it to leverage the potential productivity. Layer schemes are one example of this. Out of the box start parts from PTC rarely would be optimized for the workflow of new users.
