    Challenge: a parametric scissors lift with multiple arms.

    Want to :banghead: a little?

    A recent post by Dzatto about a lift for a car service station, left me thinking about this kind of objects. I wonder if it is possible to create a parametric scissors lift with multiple arms, like the one shown in the illustration. The details of the object are not important, nor its dimensions; that could be very simplified. The challenging part of the exercise is to make the top platform go up and down to different heights, from fully closed to fully open to a certain maximum, keeping the arms of the scissors at the same length, and joined at the ends.

              So, you found one of the (probably) many misspellings, but you did not complain about the family breaking when setting "Number Of X Sections = 1" ?? :crazy:

              :laugh:

                What the h**ll Munkholm, you are a maniac ! Shame on me Congrats

                In the mean time this morning i`ve looked again to the picture posted by Alfredo and observed that the arm system is not like my RobotV1. But like RobotV2.

                RobotV1 is the last file with some smaller formulas (last file was Robot1).
                RobotV2 arm system is like in Alfredo picture. (anyway the system is limited to eaven number of arms per vertical axis. I have to rewrite the all logical system for uneaven numbers...to lazy to start again)

                So Munkholm, please upgrade to V2 system

                  Here is an old post from Aaron's blog about array's of "1" may help you out, with some comments from Dave Baldacchino at the end

                    Thanks Mark. I know how to deal with it, but got lazy at the end Besides, I´ve never seen a Scissor lift with just 1 X section...
