RoofDraw a Bonus with RoofMaster!
*RoofDraw* is a powerful takeoff tool for roofing contractors that does not require an expensive digitizer to operate. It allows the operator to draw an accurate, 3D image of simple to complex roofs from field measurements or dimensions from drawings. The data are easy to input. In addition to providing results that usually require a complicated CAD program, (and this application is SIMPLE!), Ziatek ® RoofDraw produces all of the critical takeoff quantities, and interfaces to any WindowsT program that might be used for pricing a roofing estimate. Primary features include:

Any pitch value can be used. Standard pitches from 0: 12 to 12:12 in ½-unit values can be selected from a drop-down list. Any other pitch value can simply be typed in. Dimensions can be input in decimal format or in ft-in-fraction format. A toggle switches between the two number formats. Angles are input with a single click on the appropriate "direction arrow". Hip and Valley lengths are automatically computed from the known span of a common rafter and the user-selected pitch. Point-to-point drawing and filleting of lines is used for developing lines of unknown length and/or angles. Built-in calculator simplifies on-the-fly determination unknown lengths. Ten different edge types are drawn in a color-coded scheme, simplifying the visualization of a roof in plan view. Lengths of each edge type can be published on the screen. The published lengths are the true 3D values. Pitched areas of each polygon can optionally be published on the screen. This feature is invaluable for planning and stocking a roofing job. When two adjacent polygons share a common edge, the length of that edge is NOT computed more than once, even though it is drawn twice. A 3D perspective view of the roof can be viewed from any horizontal angle about the "equator", and any vertical angle from plan view to elevation. The 3D image can be rotated or spun about two perpendicular axes for quick selection of the desired viewing angle. This feature helps the estimator to visualize a complex roof assembly, and provides an attractive graphic image that can be printed on the cover page of proposals. The full, color-coded, 3D wireframe model can be exported to the industry standard DXF (Drawing Interchange Format) for importation into any CAD or other graphic program. Discrete quantities of PLAN AREA , PITCHED AREA , STARTER, SLOPED EDGE , RIDGE, HIP, VALLEY or FLASHED EDGE can be selected and, with a single mouse click on the "Send" button, sent to whatever WindowsT application is being used to price the estimate. The full set of values including titles and units of measure can be sent into a spreadsheet program at once. (See figure 1.)
