Learn How to Use X-Plane Move - An Easy Best Fit Move for Faster Modeling 

Part 2: 3DCS Version 7.5 – X Plane Move – How to Use The New Best Fit Move for 3DCS

Recorded Thu, Feb 22, 2018 11:00 AM - 12:00 PM EST

In Version 7.5 of 3DCS, DCS introduced the new best-fit move, called the X-Plane move. In its current iteration, it is a DLL, which is an activate-able 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. It does this by minimizing the sum of squares of the offsets between the locators.  

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 fender or similar part which could 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. 

Setting Up the X-Plane Move

What Does It Do?

  • Select as many pairs of Object-Target points as desired
  • Just like with the Six-Plane Move each Object-Target pair has its own direction
  • The X-Plane Move best fits all Object-Target pairs in their respective directions

Where Is It?

  • Available now in the release
  • Located in the dcu_mtmlib2.dll
  • User Routine is called dcsMvMinDistFit
