https://forums.autodesk.com/t5/inventor-forum/constraints-in-ilogic/m-p/5748570#M366357 I am attaching a bumper to the end of a car. If the length of the assembly of cars is 10 cars then I want the bumper to attach to the end of the 10th car. If the assembly is 120 cars I want the bumper to attach to the end of the 120th car. Am I able to do that with your methods? I am not sure which one is best to use for this situation... Wed, 29 Jul 2015 18:44:44 GMT Anonymous 2015-07-29T18:44:44Z
