Over the last year or so I have been asked more and more about "apps" for viewing SOLIDWORKS files. Now, there are many options available. There are two which I would recommend looking at.
The first one, is a partner product of SOLIDWORKS, called CADFASTER. It doesnt make your machine run any quicker unfortunately but does allow you to show off your designs on your ipad (not your iphone though).
The app itself is free and you have 100mb of space on "the cloud" where you can upload your SOLIDWORKS files to download onto your Apple Tablet. Additional space can be purchased via subscription. For more details, check out www.cadfaster.com
However, if you want to keep things simple, you can use the 3DVIA App. The 3DVIA technology is incredibly impressive. Sign up for a free www.3DVIA.com account and you have 1Gb of storage to play with. Might not sound like a lot, but 3DVIA files are much smaller than SOLIDWORKS files. Once you have your account, you can simply go to your File drop down menu in SOLIDWORKS itself and choose "Upload to 3DVIA.com." If it is not there, you can download the 3DVIA plug in for free from here.... http://www.SOLIDWORKS.com/sw/support/downloads.htm under the 3DVIA Composer tab.
On this upload window you can choose whether you want the model to be private or public.
Then on your ipad or iphone, download the 3DVIA Mobile apps. They are £1.19 but this is for 1Gb of your own models, so it really isn't a lot.
Then you log in to your 3DVIA account in your app and go to My Models. All the models you have uploaded are there. Here is a video of the process....
With the 3DVIA App, you can use the camera on the iphone or ipad2 to put your model into a picture you have just taken! A great way to show a prospective customer exactly what your design is going to look like!
Check out the other free 3DVIA technologies available on the website like 3DVIA Scenes and 3DVIA Shopper. Incredibly impressive technolgy. You can see why their tag line is "3D Everyware!"
