J-Link: Need help with Part

[cbell]

I'm trying to set the material for the current model/part using:

part.RetrieveMaterial("steel");

The issue is defining part. Sample code I have found does something like this:

Part part;

this.part = part;

I can't get this to work. I've already retrieved session and model info, I just don't know about part info.

Hi Chris -

Since you only provided three lines of your code, I might not
understand your problem correctly. Having said that:

> The issue is defining part. Sample code I have found does something like
this:
>
> Part part;
> this.part = part;

If those are two lines are consecutive, then both part and
this.part point to null (nothing). Invoking any instance
methods from either part or this.part will throw an exception.

I'm going to assume that you have the CURRENT model in Pro/E,
which your program expects to be part.

In the JLink API, Part extends Solid, and Solid extends Model.
In other words, anything that is a Part is also a Model, but
not vice-versa. So, if you have the active model already
assigned to the variable activeModel, and you want to make
sure it's a part, you can do something like this:

ModelType type ;

type = activeModel.GetType() ;

if ( type.equals( ModelType.MDL_PART )) {
this.part = ( Part ) activeModel ;
} else {
// Notify the user that the active model is not a part
}

Of course, you need to wrap this code on one or more try-catch
blocks. I hope this helps.

Thanks Mark. I'll give this a try. Another solution I got is:

Part part = (Part)model;

Which works but yours also checks for the correct type. Thanks.
