Create a reverse solid from a pocket 3

[TheeCircle]

Hi,

I was wondering if there is a way to create a solid from an existing pocket/ mold?

I have a solid part with a tapered pocket and was wondering if there is a quick way to create the male version of the pocket. I can always redraw it but thought there might be a faster method.

Thank you

John

Extract the faces of the pocket, create surface(s) to cap the pocket, then sew them together.

Extrude the edges of the pocket.

Yes, there is a way to do this that does not use the procedures outlined by cowski snd mz7dvj but it depends on the shape of the model. Could you provide either the model itself or at least an image showing the pocket that you're attempting to extract a solid representing the void?

Subtract your pocket/mold from a block, and trim.

[green]To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?[/green]

What I'm talking about is a procedure, which can be done in a single operation, with depends on deleteing all the faces of a model that are not part of the 'pocket' and then having the model be 'healed' so that all you have left is a solid body which represents the 'void'. In other words, you end up with a solid of the 'air' inside the pocket. If can upload the model or at least provied an picture of what you're working on we might be able to provide you an example. BTW, what version of NX are you running?

Hi John,

Here is a rough idea of what I want to do. It is a tapered dovetailed pocket that I am going to create a male part for.

Thanks in advance for your help, very much appreciated!

Here's my version...

That's not a solid model and there are problems with the topology. Do you have a better model?

Mr. Baker,
Based on the topic of this thread, could you create a (simple) model for us?
I did have the feeling that NX would have the capability of creating a solid using the brief description that you placed on your second reply! But I do not know how!....................

Hi John,

Try this file.

Thank you

John

It's still a pretty poor model, but even if it was a better model, this particular shape, with multiple faces that need to be created to close the 'void', you're better off trying what cowski suggested.

I'd be glad to continue this thread, but I'ev got to head for the airport. I'll be back on-line tomorrow sometime.

Have a safe trip!
We look forward to get a model from you!

How would I make that dovetail cutout in NX into the solid model?

Yes I look forward to John's how to as well!!

Refer to the model I uploaded on 1 May 14 8:53.

Hi Cowski,

Thank you for that file!

I was referring to the original solid, it was drawn in Mastercam. I can't figure out how to cut the tapered dovetail into the solid?

Again thank everybody for their ongoing help!

John

 

[cowski]

I can't figure out how to cut the tapered dovetail into the solid?

Are we talking about adding the dovetail to the NX solid model, or the machining process to make a physical part?

[TheeCircle]

Adding the tapered dovetail to the solid block.

 

[cowski]

Now that you have a solid of the dovetail, you can subtract it from the block.

Unless there is something else that I'm missing?

Thanks! Now it make sense.
