Here's a little hidden secret that you might enjoy.
In fact it's my no 1 Vectorworks 'Easter egg".
Go to the Workspace Editor>Tools>Text and add the Flowchart Node and Flowchart Link to your workspace. It's ideal for schematics!
The great thing is that you can use symbols as the nodes or just use the shapes supplied. Easy-peasy to use. Move one node and the links all 'rubber band' with it, all editable. You can add text etc etc.
In my rather pathetic attempt in the image I enclose, (sorry I'm a LD) the pictures are symbols and I've just linked them into the flowchart. So Vectorworks is Definitely the way to go, you'll never get bored only amazed!
