:: Satellite: Pitched/Residential - How To
1. Acquire a satellite or aerial image of the house from a service like Pictometry,
Google Earth or Virtual Earth. Load the image it into RoofCAD and set the scale.
2. Draw the roof outline by clicking the corners of the roof.
3. Next draw in all
hips, valleys, ridges and eaves. Use our built in library of roofing symbols to
add things like skylights, vents or stacks.
4. Now draw in the roof planes. If it
is a single pitch the roof planes can be added in one step, if there are multiple
pitches you add them one at a time. The system will prompt you for the pitch, you
can enter the exact pitch if you know it or guesstimate until you have the real
pitch from the site. Some services like Pictometery allow you to calculate the pitch,
very accurately, from their images.
RoofCAD - Digitizer has your takeoff numbers
ready!
5. To make your numbers more accurate print your drawing and head to the
site.
6. Now add the finishing touches. First you update the drawing from the site
dimensions. The length of a single eave is enough to update the entire drawing with
our unique "Rescale" feature. After that you update the pitch if it turns out to
be different from what you first entered. Finally you polish the drawing by applying
one of the predefined legends supplied with the system. If you also have a RoofCAD
license you can further enhance your drawing with photos, details, arrows and text.
You're Done!
Now you have a completed proposal drawing and takeoff record.
