Tear-Aways with Curved Perfs and Partial Cuts in 3D
Tear-Away with Perfs
Here is an example corrugated tear-away design using perfs:
In ArtiosCAD, perfs can be used for tear-aways or for folding. If you convert to 3D without setting any 3D properties on the perf, and the perf is curved, and the perf crosses an otherwise rectangular panel, like in this design, the perf is treated as Indent only, and does not make curved panels. Compare with the following design, where it will make curved panels:

If you don’t want the perfs to fold in the above design, you can set their 3D property to Indent only.
- Select the perfs.
- Press Alt/Enter to go to the Properties page.
- Click the 3D tab.
- Select Indent only.

Convert to 3D tries to recognize curved perfs that look like a tear feature and not fold them. But if you want an actual tear feature in 3D, you should label them with the Tear property.

With the 3D attributes set appropriately, you can make a tear-away animation in 3D.
But the animation and the tear-away feature is not imported in Studio Toolkit.
This design below is similar but the tear-away remains attached:

The tear-away in 3D:

Substrate Tear
This example folding carton tear-away design uses partial cuts and reverse partial cuts:

The idea is that the board will tear between the parallel partial cuts and reverse partial cuts. This is known as a substrate tear. If no 3D attributes are set, the 3D looks like this:

As with perfs, Convert to 3D tries to recognize partial cuts that look like a tear feature and not fold them. If you want to make a tear-away animation, set all the partial cuts, or all the reverse partial cuts, to Tear in the 3D page, and the result in 3D looks like this:
