    I believe that example in the manual is of a "SimforceGT" type rig that both motors have to move together. If you gave each 100% of a sway or roll motion, there'd be no motor rotation left for pitch when you max that sway or roll.

    The axis assignments give a force a percentage of the physical travel on that axis. If it's under 100% and there is another force also on that axis, the position of that block of percentage can float over the length of that physical axis when the other force moves from center. It's hard to explain. A visual aid showing how the data ranges scale, move, shift, overlap, etc would help.

    The manual is an example of a 100% allocation of an axis. You can choose what makes up the Axis Allocation and as already pointed out SimTools even allows say a 2DOF to have a motion profile Axis Allocation that includes roll, pitch, sway, surge, and simulated heave, with each being an Axis allocation on each of the 2 axis. How much Axis Allocation is allocated to each depends on the rig, the game and motion profile tuning preferences.

    I'm confused about this either,I'm wondering whether a DOF means a actuator.
    If I set DOF1 as pitch 100%,does it means the front actuator would extend and reduce?

    Grab a copy of the SimTools manual and keep it handy for reference: https://www.xsimulator.net/community/faq/rtfm-start-with-the-official-simtools-documentation.117/

    As I previously posted you can choose what makes up the Axis Allocation, SimTools even allows say a 2DOF to have a motion profile Axis Allocation that includes roll, pitch, sway, surge, and simulated heave, with each being an Axis allocation on each of the 2 axis. How much Axis Allocation is allocated to each depends on the rig, the game and motion profile tuning preferences.

    The Axis Allocation is what % of the total axis each force has. The Tuning Center settings determines how the rig reacts with respect to that allocation.

    You should first capture the Max/Min values in the Tuning Center, the tweak from there. The larger the Tuning Center Value the smoother the responds, over a greater range, the smaller the Tuning Center value the sharper the rig responds, but over a smaller range.
