CAD files can get to quite a size. Sending them to other people can be a nightmare. There are a number of ways they can be sent to view and review but sometimes you just need to send the actual native files.
There are a number of options. You could use a tool like Skype or Windows Live Messenger to send the files over but this is not very convenient if the recipient is not online at the time you need to send them. FTP sites are a useful alternative but they are not always that simple to use. They also require someone to set them up, manage them and you need to remember more passwords!
Recently, I rediscovered a website called YouSendIt.com. They offer a range of services for transferring or storing large files.
The most basic service they offer is completely free of charge and lets you send files of up to 100mb at a time up to 2Gb per month. It is very easy to use and there is even an add in to Outlook which lets you create an email as normal, click the YouSendIt Attachment button rather than the normal attachment button and it attaches a link to the email and uploads the file to yousendit.com all in one go. The recipient then clicks the link on the email attachment and it downloads the file. It's incredibly simple and very convenient for everyone involved. No extra work and no passwords to remember!
Give it a try, you have nothing to lose. Great for sending us those big models you need some support with. You do not even have to enter any credit card details to use the free trial of their higher level services.
