revolved cut with a body? 1

[skanskan]

Hello

¿Is there in NX an option to "cut" a body with another body?, (revolving the second one through a path). Where?

That option exists in Solidworks, so I guess it should exist in NX too.

Look for the "subtract" command. You can find this in the menu at Insert -> Combine -> Subtract (assuming NX 7.5). The body you want to remove material from is referred to as the "target" and the 'cutting' body is the "tool". You can perform the subtract at the time you create the revolved body, or do the revolve and subtract in separate steps.

If you are having problems finding a command go to: Help (pull-down) -> Command Finder
It is OK to enter the command as it is called out in a differnt CAD system.
The "Command Finder" icon can be toggled "on", on your "Standard" toolbar.

You can also try in the REVOLVE dialog, Boolean > Subtract

NX6.0.3.6 -> NX7.5.4.4 -> NX8.0.0.25

Hello and thaks for your answers

But how can I sweep the body?
Once I choose sweep the only option I have is to choose a curve but not a solid body (the tool I want to use to cut).

Imagine I want to use a cube to cut a cylinder, and be able to specify the rotation of that cube.

expand everything in that menu, there's lots of options available

You can't sweep solids (at least not as of NX 7.5). Define your cross section and sweep that instead.

Oh!, it's a shame

I thought I could, NX it's a high end software.
I think some others like Topsolid can

I meant it's a pity.
My English is not good.

Try using the FACE of the solid body as your section for the Sweep - if that fails to work, Extract the edges and use those. As always, an example part file is usually helpful, if possible.

Hi Xwheelguy,
I don't have the example yet, I'm speaking in general.
Using a face of the body is only a good idea if it isn't rotated.

Well, you've lost me - now you're adding more criteria than what was intially posted. Come up with something visual, then we can probably give you better direction. I'll use faces for different types of Sweeps (which by generic definition, are the NX commands Extrude, Revolve, Swept, Sweep Along Guide, Variational Sweep and Styled Sweep) all day long, as long as those faces are PLANAR or I am able to construct the path/guide perpendicualr to the section - and if it wasn't good to use them, I highly doubt they'd be available as a valid choice for the sections. Granted, I have absolutely NO CLUE what you're trying to model here, so I am at complete disadvantage.

Now, forget how Solidworks does things (I don't have a problem with Solidworks, just don't think in those terms) - think of how you want to create the bodies (Extrude, Revolve or Sweep). If you can get the bodies to intersect COMPLETELY as solids, then simply use the Subtract command - the Target will be the body you keep and the Tool is the "cutter". If you can't get the bodies to completely intersect as solids, there are other options that might work using sheets (surfaces) such as Trim Body.

You're going to quickly find that there are many different ways to skin a cat in NX - there isn't going to be ONE command that does ONE job, like many of the mid-range softwares might have.
