I know this is a hard question but i thought i would ask anyway. I am taking an Ai file of a CAD drawing of a train but i have far too much detail for the task that i need it for. The train is made of vetor lines so does anybody know a quick way of filtering the ones that i dont need without loosing the outline and partial details of the body. ATM i am having to select and delete everyone seperately. You may also know about CAD so would there be somekind of thresh hold setting when saving.
