Cylindrical Datum Plane? 1

[mxrethoret]

I'm trying to cut out part of a block using the angled surface of cone-shaped part. Since I need to cut off ALL material past a certain surface, a simple subtraction won't work as it would only create a channel in the block. One way of going about this, I was thinking, would be by establishing a datum plane that followed the cone-shape. Then I could split the body and delete it from there. Is this even possible in UG? I understand that datums, by definition, are flat surfaces but was curious if there was a way of rounding them out at all. I am using NX4.

Sorry if this is a dumb question. I'm still learning the software, without any formal training. Thanks in advance!

Please provide at least a picture/sketch of what it is that you're attempting to model.

no such thing as dumb question, grasshopper.
You don't need a datum so much as a tool body or surface to clean up or trim to. As John notes, a picture would help much.

Yes, a picture will help, but that being said I'm imagining a scenario where I would extract the face of the Conical solid body as a sheet body and then use the 'Enlarge' function to increase the extents of the Conical sheet body until they're sufficient to cut through the entire block.

ewh... I am familiar with the process of creating solids to use as subtraction tools. I actually ended up doing it this way. But there have been other situations where having a conical plane to cut with would have been really handy.

John.. Unfortunately, I cannot post a screenshot for security reasons. However, your thinking is on track with mine. Would you mind walking me through the process? The only face extraction I've done at this point is extract geometry.

Thanks for your help guys!

Note that this is just a guess of what it is that you might be trying to do, but...

Open the attached NX 4.0 model and review the features in the Part Navigator. Do an 'Edit with Rollback' on each of the last 3 features to see what I did and how I used the various options.

If this isn't falling near to what you're doing, please providing something which would show at least some aspect of what it is that you're attempting to accomplish, at least enough so someone could work-up a simple example like I attempted to do here.

The closest thing to a cylindrical datum plane would be a sheet body cylinder

That's exactly what I was trying to do. Thanks for your help John!

Good communication requires understanding of the terms being used... it is impossible to have a conical (or cylindrical) plane. ;-)

Is that anything like an astral plane?

Oh, there I go using an absolute... which I abhor.
Let me qualify my statement with "In our current physical dimension, as of yet it is impossible... as far as I know."
