Hello fellow autocad users, I have been working in the field of material handling for the last few years. I discovered that most conveyors are not shown correctly when they are inclined and rotated off the x y z axis. So in order to correct that situation I have wriitten an autolisp program to model trusses in 3d. This program will model trusses in belt widths 18 to 96 inches, 24 to 60 feet long and truss depths of 24 to 60 inches. You specify all the material in the truss. you also specify if you want a walkway, left, right or both and walkway material. I have enough programs to model the entire conveyor including bents, skirtboard, take-up, channel frame and the head chute. I also have routines to model all the required purchased components. I would be glad to share these programs with anyone who might be able to use them. email request to gregculjan@otmail.com
