Quoting from official announcement:
I have finally decided that since I do not have an immediate need for additional objects, I’ll go ahead and release my current Visio Stencil set that I have been working from…
While there are only six objects initially, I will be continuously adding more as I find the need for them. I will also watch for requests in the forums and attempt to meet specific requests that I can find useful.
Please head over to the downloads section and check them out. Your feedback is welcome.
A great job guys! Many thanks for this jewel.
