Yes, this is possible, but how to do it depends on the version of Mathcad. This is not the main forum, which is here: http://collab.mathsoft.com/~mathcad2000 Log in and go to this thread: http://collab.mathsoft.com/~Mathcad2000/read?133770,11e#133770 That forum also has much bigger upload limits, although still not 3Mb. You can make the file much smaller if you go to File, Properties, XML Options, and select "no images" and "don't store large evaluated results". Then save it as a compressed XML document. If you post a file to the forums it can be a good idea to post it in version 11 .mcd format for a wider audience, but sometimes you can lose stuff in the file if you do that. Richard
