I can't undersand, how I can create linear actuator model in MapleSim and to add it in 3D-visualized project. (Like this, for example: http://www.hiwin.com/images/lai2_series_linear_actuator_large.jpg).

Can anyone share an example of such task or explain to me?

It is possible without electric motor and transmission.
An example of translational motion with a certain force will suffice.

Thank you in advance for your cooperation!
