Orient objects with "Remap CPlane"

0 0 Intermediate
The ! _RemapCPlane command lets you orient (and copy) an object across already saved CPlanes. This is especially useful for situations where the goal is to be able to quickly place copies of the same object(s) onto another CPlane, such like placing a home door in a closed and an opened positions using the CPlanes as a reference. An alternative method is to use the ! _Orient3Pt command, though it will require to manually pick 3 reference points followed by 3 target points for every time you need to orient new objects. This is where the ! _RemapCPlane command unleashes its full potential as it only requires two (or more) saved CPlanes initially, then every next copy-and-orient operation happens by double-clicking on the target CPlane listed in the "Named CPlanes" pop-up window.

Super hack to create hollow objects for 3d printing in Rhino

0 0 Beginner
This is a quite easy “hack” how to create hollow objects that are usually not allowed by other CAD programs. Great for 3d printing. Simply connect the outer and inner objects via some random pipe or box, then join everything and untrim the hole that connects them with the ! _Untrim tool. You will notice that the two original separate objects now appear as a single object instead, despite the lack of an actual connection in-between. An alternative way is to select both objects and use the following commands: NonManifoldMerge, then CreateRegions, then delete the region you do not want, such like the core inside the sphere in this particular example.

Loft magic

0 0 Beginner
When it comes to organic NURBS shapes like that, nothing can beat the quality, simplicity and History-enabled modification that Loft with the “Loose” option provides. A good practice is to use profile curves with the same degree and amount of control points. I started by creating the round base by using the Circle command with the “Deformable” option and 8 control points. Then, I simply copied it a few times and modified each one individually by moving its control points in the desired location. I also used Scale 3D and Scale 1D to adjust the overall size of each profile curve. As I moved or modified each intermediate curve, the History-enabled Loft surface updated in real-time, thus it let me decide what changes I needed to make to achieve the desired shape. NOTE: In this example initially I used the “Normal” option of Loft, which is not a good way to do the shape. The video capture was interrupted for some reason and stopped far earlier, so you will not see how I then deleted the loft surface and create

Match surfaces manually

0 0 Intermediate
One disturbing issue with "Match surface" is that it will try to transfer the 1st and 2nd row of control points to the target edge while keeping the distances between them relatively unchanged. This is usually great for the majority of users, because it's predictable and even usable in specific cases. However, there must be an option to "unclock" the aforementioned correlation between the 1st and 2nd row of control points and instead let "Match surface" adopt the same distances as the target control points. With that option turned on, the surface to be matched will become perfectly matched to the target one. To demonstrate the HUGE advantage of a potential "Adopt" option that I just described, here is a simple way to achieve the necessary correlation between the 1st and 2nd row of control points by "mirroring" the distances from the target surface to the opposite one. Lets hope that "McNeel" will consider adding such an option in the future releases of Rhino.
