I am trying to get a belt to go around those 3 rollers but I get a lot of mate errors when I use the belt/chain feature.
(very new to solidworks)
Have you tried unchecking "engage belt" when checked it creates belt mates between your rollers which will make them rotate together as though connected by a belt but if your rollers are not already free to rotate it will cause mates to go over defined.
For anyone to be able to help you, you'll need to include the part files too. With the assembly open, go to File->Pack and Go and create a zip file of all the files then repost.
welcome to solidworks chris!
here's a tip:
if you want to share an assembly you need to include the parts that make up the assembly along with the assembly file itself. an easy way to do this(even if the parts are located in different folders/drives) is to use Pack-N-Go. this will scoop up all the related files, place them in a folder of your choice and even zip them up.
because right now none of us can open your assembly as it is looking for parts on your local pc/network.
As you know, all we can see is the picture, so this may be out of line. Are you trying to make the belt be openended, as in go under one lower roller, over the top one, then back under the other lower roller and out the end? If so, you can't with the Belt/Chain feature - it only does a closed loop. You have to do it manually with a sketch and a sweep.
Also, if one of the rollers is fixed the belt/chain feature will be unhappy.
andrew i'm going to bet that's his problem. i opened the assembly file in edrawings so i could atleast get a look at the assembly. it appears that his rollers probably don't actually "roll" and that would be why the "engage belt" would be giving him trouble.
Sorry about that guys here it is zipped. Looking at your responses though, that is probably my problem because right now the rollers dont actually move
Thanks for all your responses
