The X-Plane move is a 6-Plane move that allows for more than six pairs of features to be selected and then best fits your parts. It is a powerful move that can be used in a large variety of situations and may become your go to move for modeling in 3DCS. Learn how to use it, and see a number of example models to start using this new move. 

How Does It Work?

A typical part with rigid body analysis only gets six locating features, generally a 3-2-1. For not over-constrained, this works great. However, if you have a fendor or similar part which ccould have multiple locators, the 3-2-1 move will not properly represent its attachment. To model it, traditionally, we use autobend moves with some tricks, or to properly model it we'd use Compliant Modeler with an FEA Mesh. However, that can become complicated, as it does require a FEA Solver, an add-on, and some knowledge of FEA modeling. 


To help solve this issue, then, we've introduced this new best fit move, called the X Plane move. In its current iteration, it is a DLL, which is an activatable extra move that is downloaded with the standard software and just needs to be turned on. This move will soon be built into the main platform with its own GUI. 

X Plane lets the user add all of the locators and automatically best fit the part. The X-Plane move minimizes the sum of squares of the offsets between the locators.  

So, the example below, we chose 11 features to fit the part, each with its own direction, and the part is fit using the best combination. 

For better illustration, here is a short video from the first part of the 3DCS V7.5 Webinar Series:
