Problem with rip command

[SCASTILLO-RMI]

Attached is a simple reducer cone made from 14 ga stainless. I am trying to rip it to create a flat pattern, but despite following the step by step on several youtube videos I can't seem to get it to work.

Please take a look and let me know what I am doing wrong.

Thank you

Hi,

In attachment is file created in I2022.2. I removed shell feature and used Thicken on surface feature. Thicken feature adds material normally on surface what is necessary for sheet metal.

You will also need a line or point to point on the surface of the cone where you wish to create the Rip:

Thanks for taking a look. Unfortunately I can't open the file as I am running 2021.

That said, I have used the rip command successfully on other parts that featured the shell command.

What is different about this part that shell needs to be removed?

Yes, I have done that by following the example shown here:

I get as far as choosing the two points and then get an error message.

This cross section for shell

This is from Thicken

This is your modified sketch

Pay attention revolve will create surface

Cteate WorkPoint for rip

Apply rip on one point

Hi, I forgot two important things.

1 For thicken command input desired thickness

2. Convert your model part in sheet metal part

Thanks for the pics, they pointed to the problem. I squared off both edges perpendicular to the rip line - as you show in your second pic - and the command worked.
