Topic: get dxf values of a selected object

[BenJones]

Noob to .NET...migrating vba to .net (see faces cringing now)...

I see that you can create dxf selection filters, but I want to select an object and get the dxf codes. I have checked the object browser and done a couple of google searches and come up with nothing.

Anyone have a snippet that I can snag or some leads on how to get this info?

you can p/invoke entget

Why do you want to get to DXF codes?  What are you trying to do?

Thanks Daniel. I will try this out.

I am using adt schedules and they keep the their object selection in soft pointers.

So the idea is this, select a ADT schedule object and create a selection of objects that it is associated to.

Autodesk hasn't opened schedules through the api at all, so I am looking for ways around this. Any ideas?

Thanks again!

Ben
