Hi Is there any website or place that can buy Cad files or building way of machinery ?for example pvc extrude machine or sachet packaging machine?thanks

I have one for architecture, but haven't seen one for machinery drawings. Here's a thought... When I want special details from a certain manufacturer like one that makes windows and doors, I look for their website. You usually find pre-drawn details there. So look for a fabricator that makes something similar to what you are wanting and see if they have something online you can use. Just a thought...

If you buying a specific piece of machinery CALL the manufacturer and tell them you are looking for a block to insert into a drawing you are creating.  Some companies, knowing you are purchasing from them, will extend users the courtesy of sharing their in-house CAD drawings.  They are not going to post everything they have online.

HelloOnce I have had a similar requirement, but after years of searching sites, forums, services with 3D & 2D blocks and sites of manufacturers, I realized that each jealously guards its secrets. Especialy detailed documentation.So I decided (with few engineers) to run own service with complete machines 3D&2D documentation to buy and for free download. If I knew the other sites with similar themes - I would recommend. But I do not know so I recommend my own. There is currently small amount of projects but we constantly enlarge it and improve.If someone is willing to look at it I invite: www.papacad.com

What kinds of machines?
