Question

Automatically Suppressing/ resuming features in a group or layer using pro program

Is it possible to suppress layers using relations or pro program?

 

I have a part with all of the features possible built in and I suppress the features I don't want using parameters, relations and the model pro program. 

 

The problem I am having is when I need to add another feature to a group. When the new feature is added to the model tree in the existing group of features, the model program automatically adds an "end if" statement before the feature and the existing conditional statement after it. This essentially creates an island in the middle of the group that does not become suppressed with the group around it. On simple parts this is not a big deal as I can go in and fix it easily enough, but as the parts get more complex it gets much more complicated. Also, none of my coworkers are knowledgeable enough to editing pro programs at this time.

 

What I want to do is put all of the features that should be grouped together on a single layer and then just use relations or pro program to suppress or resume the layer. Then I can just name the layers by the customer option and everyone will be able to add features to the layer as needed.

I do not think a relation will execute a suppress command. You can definitely select for suppression all of the features in a group or on a layers using the search tool. I have used mapkeys to resume and suppress features by layers but not Pro/Program.

 

I have not tested this in the context of Pro/Program but it should work for selection.

 

You can use the search tool to select all members of a group for inclusion in a layer. By extension you should be able to create a rule to assign features to a layer that should update each time the model is regenerated. This may alleviate the Pro/Program issue with adding ENDIF, worth a try. If this does not work consider adding markers (I use empty annotation notes) to the model tree and ungrouping the features and then making a rule to add all features between the markers to a layer. The markers will have a unique feature ID that will allow you to track them no matter where they move in the tree.

Thank you for the quick reply. 

 

I am able to get the features assigned to a layer no problem. The part I can't figure out is how to actually suppress a layer or the contents of a layer from pro program. Is that even possible? Is there a better way to model a configurable part?

 

I should probably mention that I am running creo 4.

 

Thanks.

I am not an expert with Pro/Program but I have looked at using it to execute some other commands and struck out. I Don't think Pro/Program has the ability to suppress the layer because that is done through the new UI elements.

 

In terms of managing configurations there is Creo Options Modeler extension. I know very little about it but it may make configurations mush easier. You would have to buy that but I am sure a trial license would be offered to test it.

 

There are multiple options available for "configuring" parts/assemblies such as simplified reps I would need to more about the design hierarchy and what needs to change to offer more guidance on that.

 

There are also Excel based configurators that can control a master assembly and eliminate parts for different versions. Otis elevator had developed one back in the 90s and I am sure the options have improved since then.

 

Family tables work for things like bolts/nuts etc. I am not a proponent of using them to represent complex geometry/models especially if you are using Windchill. They can become a nightmare to manage as complexity expands. Strictly within Creo I would try the top down design tools and Pro/Program rather than family tables.
