By Joe Stoddard Ten years ago I coined the phrase "CAD-Assisted Estimating" to describe early attempts by CAD vendors to provide take-off and bill-of-materials functionality. Those early versions were crude (and costly) by today's standards. Now, using CAD to automate the take-off process can be a reality. Three programs I often recommend to builders are SoftPlan Pro, CADSoft Build, and VectorWorks Architect.
SoftPlan Pro. SoftPlan is easy to learn, powerful, and flexible, making it ideal for custom builders. The take-off module can count items on the drawings or calculate materials/labor from user-defined assemblies. How and if a material is included in the estimate is completely configurable by the user, and custom formulas can be created to pick up materials or labor for special items. Cost: $2,785. www.softplan.com.
CADSoft Build. Build and sister program AP Design are based on AutoCAD technology, ideal if you already have AutoCAD expertise or need to share drawings directly with your AutoCAD-packing engineer. CADSoft's framing take-off module especially shines, and like SoftPlan, Build offers flexible reporting options. Cost: $2,995 to purchase; it also may be leased monthly. www.cadsoft.com.
VectorWorks Architect. VectorWorks is the most customizable program of the three. Programmers can access and manipulate information on the drawings, making it a good choice for larger builders looking to build a more customized CAD/estimating solution. It's also the only program of these three that's available for both Mac and PC platforms. At $1,295 (base), VectorWorks offers a lot of bang for the buck. www.nemetschek.net/architect.

Keep in mind this is CAD-assisted estimating--the key word being "assisted." Most builders will still need to tweak results in a spreadsheet or conventional estimating software. Also, don't expect the systems to set themselves up: You'll burn some midnight oil testing configurations that best represent how you build and price projects, but in the end the added automation will be well worth the effort.
