Is there an existing issue for this feature request?

I have searched the existing issues

It is currently not possible to "insert length" into an object. It is possible to scale an object along one (or multiple) axis, but this changes the properties of the whole object.

This feature suggests allowing a possibility to "insert length" into an object along a defined plane.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

This feature suggests allowing a possibility to "insert length" into an object along a defined plane.

Picture the "cut" feature, where it is possible to define a plane along the model where it should be cut, but instead of the cut, it is possible to "insert material" perpendicular to the cut face.

This feature differs from "scaling" along an axis, as scaling would elongate the whole object along said axes, whereas this enhancement request seeks to simply allow for adding n millimeters of "length" to the left and/or right along the defined "cut-"plane (perpendicular to the defined plane).

Describe alternatives you've considered

Right now, I cut the object once, then cut again, then create instances of the cut out part, arrange it on the print plate, and "merge" it together.
This is really tedious, and also requires keeping track of the inserted path. Also, aligning them exactly is a must and takes time.
