Adding a cross hole to a 3d part

[ScubaSteve]

Hello, can anyone help me put a hole through the side of a 3d cylindrical part?

I had trouble uploading a screenshot of the part, and I apologize for this awful drawing. Essentially the hole through the side of this crudely drawn cylinder is what I need to add. I am using AutoCad 2000. Any Ideas?

Create another smaller cylinder then subtract it from the main (larger) cylinder.

[ScubaSteve]

Is there a command for subtract?

[ReMark]

Is there a command for subtract?

Why yes there is. It is called SUBTRACT.

[ReMark]

Subtract one cylinder from another. I sliced the resultant solid so you could see that the hole passes all the way through.

Thanks a lot! This is my second day using autocad and you just helped me replicate a pretty complex part in 3d. I bet my boss will be impressed!

[ReMark]

You're entirely welcomed.

Again this creates a problem, I am on a really old pc and cant save the screenshot in anything but .bmp. How can I add a chamfer to the edge created by the subtracted cylinder?

[ReMark]

Use the FILLET command. I think that will give you the results you are looking for.

[ScubaSteve]

What's the difference? Im sure which one I need

[ReMark]

See revised reply.

[ReMark]

Is this what you are attempting to do?

[ScubaSteve]

Yes exactly. How do you accomplish that?

[ScubaSteve]

Maybe I could just subtract the tool from the part?

[ReMark]

I used the FILLET command as previously stated.

 

In my line of work a chamfer is treated like a beveled edge (ex. - 45 deg angle) where as a fillet is considered a rounded edge.

[ScubaSteve]

did you see the picture?

[ReMark]

Yes, I saw the picture.

 

If you want to subtract the tool (or a copy thereof) from the part then by all means go ahead and do so.

[ScubaSteve]

Thank you very much for your help!

Any computer of any age (this century) should be able to save screenshot in jpg or png format.

Hit Print Screen or Alt Print Screen to capture entire screen or active window.

Open MS Paint and Ctrl V to paste the image.

Save as file type *.jpg or *.png

Attach file here.

 

Presspull works easier than extrude and subtract.

For machined type chamfer (revolving tool) you must to a Revolve and Subtract to get correct geometry.

 

A fillet an chamfer feature are not the same.

Hand tool deburr and machined feature are not the same geometry.

I don't recall a PRESSPULL command in AutoCAD 2000.

 

And I agree that there is a difference between fillet and chamfer. Some people tend to use the wrong terminology.
