I'm using SmartDraw 2010 software. If I click the engineering diagrams they are not loaded (it shows an "Unable to download" error). I need to work every time with an Internet connection. I want to work without Internet connection. Can you help me?
Unfortunately, as you can see in the Internet Connection section from the official web page, SmartDraw will need to be able to connect to Internet in order to use it with all its functions. I suggest you contact the developer for further information. You can get in touch with them using the How to Contact Us page.
