Hello folks,

Would you care to share some pointers to drafting software which you use to draw up architectural drafts (for telecoms networks, including cable operators' networks) ?

I've found Visio to be a bit weak in this respect, even after adding third party stencils.

One product I'm exploring is ConceptDraw's "diagram" product, but I'd like to hear about anything you can share with me.

Cheers,

Etienne
