Hello folks, I cannot work out how to copy this face to then extrude as a new body.

 ![2024-02-02_21-13-57](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/3X/0/0/00c4a7d832339131db3c6d6a8b722bac214465c3.jpeg)

In F360 I can extrude and set as a new body, but I can’t work it out in Shapr3D. any advice?

Hi @HarrisonDavies

Instead of copy then extrude, just extrude then change the type to **new body.** In the parametric version you can change it after the action.

After you start your extrude, look for the little icon showing the type of extrusion:

Click that icon then change to New Body. From there you can position it where you want it.

Okay, it only appeared after I selected the input field and entered and number and hit the tick/check mark is that correct behaviour?

For the devs, it’s now functioning with the arrows after having input the number.

I almost always drag the arrow to start the extrusion, but yes, you need to start it by dragging the arrow or putting in a number. When you have one sketch and extrude, you won’t get the option to change the type, it has to be a new body. If you extrude into another body then it will automatically change to Subtract. When you start the extrusion that intersects with a body (like the example above), it will default to Union.

And sometimes, if you are extruding such that it would create a non-manifold body, you won’t have a choice, and a new body will be made. (Or it will give you an error)

Thanks, Bob, I do think it was a glitch/bug. Wouldn’t appear on drag, until I’d input. a number. May have been an issue with the model?

Now it appears each time on drag and input. hopefully doesn’t happen again.

Thanks for the help.
