<p>Yes, as of Ultimaker Cura 3.3 Beta, Ultimaker Cura allows you to specify an area which will not be considered for adding supports. In your case you could define everything above 4&nbsp;mm to be excluded from building support structures. </p>

<p>Ultimaker Cura offers a platform support type of “<em>touching buildplate</em>” which enables the printer to only make a raft for parts of the object that should be touching the build plate. It also offers “<em>everywhere</em>” for any object that might be hanging over the build plate.</p>

Why don't you care about overhangs higher up?  what "magic" allows those to print properly but not the lowest overhangs?  What's the real concern here?

Basically, I have an irregular structure where I need to arrange it in a certain way to limit post-print-finishing. The support structures cause some of the irregular structures to snap off when it’s removed from the print bed. I don’t think sanding or acetone baths are a good way to smooth ABS -perhaps that’s the real problem here, I need to hide support structure connections prior to post-finishing, and this irregular surface is the only spot to do that. These high-up overhangs have a very low angle of overhang and should connect fine without support

Ultimaker Cura offers a platform support type of “*touching buildplate*” which enables the printer to only make a raft for parts of the object that should be touching the build plate. It also offers “*everywhere*” for any object that might be hanging over the build plate.

I have a need to only offer support for overhangs up to a certain z height, such any overhang located at a z-point of 4 mm or below. Is there a software that will enable this, either as a setting/addition to Ultimaker Cura or just a G-code export for Pronterface?

I don't own a copy of it, but from talking with other 3D printing enthusiasts, I know [simplify3d](https://www.simplify3d.com/) is the slicer out there with the most granular control over support structures.

I'm unaware if it has a setting for *exactly* what you want, but I know it has the possibility to manually add support in selected parts of your model, so - depending on size and complexity of your model, and on the level of accuracy you need - it may well be an option for you.
