Can you think of anything that would prevent GePrint () from printing to the console? It seems like it's not recognizing that the checkbox was checked.

Without any additional code it is hard to say. Maybe the description resource for the checkbox is wrong.

Please do, because the description resource seems to be ok.

Btw. is the Draw() method called at all?

If this does not show the problem I can email you the whole contents of the .cpp file if you PM me your email.

Thanks so much Matthias for taking the time to help me out.

I just realize that your Draw function has a wrong declaration. For TagData plugins it looks like this

virtual Bool Draw(PluginTag *tag, BaseObject *op, BaseDraw *bd, BaseDrawHelp *bh)

Your Draw() method is probably never called.

Matthias

how do I remove the polygon after I have drawn it? I am able to draw a polygon on the symmetry plane now but I want it to go away after they uncheck the bool.

Finally, the last step I need to do is to get the polygon that I have created, aligned, resized, and changed the color, to stay locked to the object on which the tag is.

For example, this portion of my plugin creates a visible symmetry plane on an object. I would like this new polygon to stay attached to the object no matter where it is moved around in 3d space. Can someone point me in the right direction on how to accomplish this?

Thanks,

Multiply the position vectors of the polygon with the global matrix of the object.

Btw. I recommend to really go through the SDK examples as they often provide a solution to your problem.

In this case it's just basic vector/matrix algebra. The examples are full of it. If you haven't done it yet I recommend to get familiar with vector/matrix algebra. There is an excellent introduction in the COFFEE documentation called " Using matrices".
