AppliCad’s advanced measure technology increases accuracy

Incorporating the most innovative features in specialised software for roofing and cladding take-off, AppliCad’s aerial image hip and gable pitch measure technology has been described as “the holy grail of aerial measurement tools.”

As simple as 1,2,3 – Import the oblique image, drop the 3D axis indicator (CPL) on the corner of your building image aligning the 3D axes with the roof edges and measure the pitch of the gable end or the hip end of the roof. Measure the pitch to plus or minus one half of one degree!

It really is that simple. Using regular 3D CAD functions for aligning the job origin and some vector math for measuring angles (roof pitch) AppliCad has a universally beneficial tool for AppliCad roofers who regularly use aerial images for preparing roof estimates.


Import the aerial image and locate the 3D construction plane (CPL) axis icon.


Align the construction plane (CPL) axes and measure hip-end pitch on the sides and the front of the hip end – 8/12 hip sides, 12/12 hip end! Record details for later use.



Repeat for other roof areas as required.

Working in a true 3D CAD environment has many advantages. The ability to align a 3D model with a 2D image is just one of those and this affords us all the power of embedded 3D CAD measure tools.


Side pitch is 12.00 in 12
Front pitch is 16.52 in 12
‘A’ – Inc. Side Pitch, ‘Z’ – Dec. Side Pitch, ‘S’ – Inc. Front Pitch, ‘X’ – Dec. Front Pitch, ‘F’ to Flip Hip about X-Axis

Once the measured, the pitch information is then used to help roofing estimators accurately model their roof geometry in 2D, accurately reporting 3D areas and lengths, or in full 3D reporting areas and lengths of roof features.  AppliCad is the only software on the market that provides either option.  A 2D model allows the operator to prepare a reliable take-off, even if the roof geometry cannot be physically built because of errors with the design.  The 3D model proves the design will work, but may take longer to complete in some instances.  So long as the operator understands the relative merits of each process, they can balance speed with accuracy for optimum result.

With either the 2D or 3D model, the operator simulates the application of all required the roof materials, from panels to gutter to downspouts, then calculates labor and material costs and generates the results in your standard MS Word report templates, and you’re done.

AppliCad is very excited by this refinement to our 3D CAD construction plane (CPL) and the pitch measure tools, and roofers will be too. They can now develop accurate take-offs for quoting purposes for all roofing materials and labor without the risks associated with climbing all over the roof and in their own time frameno more waiting for third party services. Whether a regular re-roof or an insurance claim job, the tools save a heap of time preparing bids.

With roofing software being so cost effective, processes can be automated with even greater productivity improvements, improved accuracy, reduced waste and much more professional presentation of quotations, purchase orders and roof drawings.  Quotations may now be completed in minutes instead of hours and a complete set of job documentation is created for the job file using tools that you are familiar with such as Microsoft Word and Excel. 

Implementing the right technology with the partnership of the right software vendor will ensure that a roofer’s expectations are met and their business continues to grow in turnover and is more profitable on each and every job.
