I like how easy it was to use this program compared with other programs we had been using previously (such as AutoCAD). It's not perfect but has really helped us out! If you're looking something simple yet helpful then definitely try Family Manager first before trying any others because there have just so many features included within one product now days - sometimes too much choice!! We've used several different CAD software packages over our career; however none of them were able compare when dealing specifically w/ construction drawings & specifications management than FAMILIARITY WITH THE PROGRAMMES INTERFACE AND USER FRIENDLY FEATURES FIRST.
