This should produce a lot of output. This is the interpolation table that checks the compression of the gear strut and derives the angular deflection of the scissor arm. It should look like this: | This should produce a lot of output. This is the interpolation table that checks the compression of the gear strut and derives the angular deflection of the scissor arm.

Your numbers will look different but the structure should be the same. Save this output into a file named '''GearScissorInterpolation.xml''' and save this file in the same folder where your 3D model lives. | Your numbers will look different but the structure should be the same.

Before you continue, locate the rotation points of the two scissor arms where they are connected to the main strut. These are the vertices that were marked to measure the scissor distance. | Before you continue, locate the rotation points of the two scissor arms where they are connected to the main strut.

Fill in your values for x-m, y-m and z-m for the location of the rotation vertices. Add another section for the second scissor arm, replace the object-name with '''B''' and set the axis to +1 instead of -1. | Fill in your values for x-m, y-m and z-m for the location of the rotation vertices.

If you see the scissors move in the opposite direction, exchange the sign in the axis definition. | If you see the scissors move in the opposite direction, exchange the sign in the axis definition. | ||
