Canvas vs Apex Sketch: Which Is Better for Residential Appraisers?

Canvas and Apex Sketch are both used by residential appraisers — but they solve the problem from completely opposite directions. Canvas scans the home automatically with an iPad Pro's LiDAR sensor. Apex Sketch is desktop software where you draw from your own field measurements. Here is a direct comparison.

The short version

How each tool works in the field

With Canvas, you walk through each room with your iPad Pro raised at shoulder height. The LiDAR sensor maps the walls, corners, and ceiling automatically. After the scan, Canvas generates a 2D floor plan that you can review, correct, and export. The entire capture for a typical 2,000 sq ft home can take 10–15 minutes — comparable to shooting listing photos.

With Apex Sketch, you take your own measurements on-site (laser or tape measure), record them in the field, then enter them into the desktop software back at your office or in your car. Apex Sketch uses a directional input method — you enter wall lengths and turns sequentially to build the floor plan. GLA is calculated automatically as you sketch.

Which is more accurate?

Canvas LiDAR accuracy is typically within 1–2% on clean rectangular rooms. Complex layouts, open floor plans, and glass surfaces can reduce accuracy. Apex Sketch accuracy depends entirely on the quality of your field measurements — a careful appraiser with a good laser measure will often produce more defensible results than a LiDAR scan in a challenging space.

For appraisal purposes, the key is reproducibility and documentation. Apex Sketch gives you a clear audit trail — you enter every measurement explicitly. Canvas gives you speed but requires verification of the scan output, especially at room boundaries.

AMC and workflow integration

Apex Sketch is a Bradford Technologies product and integrates natively with ClickFORMS. If you use ClickFORMS as your appraisal platform, Apex Sketch is the natural companion. The sketch and GLA flow directly into your report form without manual transfer.

Canvas exports floor plans as PDF, DXF, or PNG files. It has a ClickFORMS import path, but the integration is looser than Apex Sketch's native connection. If you use a la mode TOTAL, you would import the Canvas export rather than having a live link. Canvas also integrates with CubiCasa's infrastructure, so some workflows combine both tools.

Where PlanSnapper fits

Both Canvas and Apex Sketch are field tools — they capture or build the floor plan. PlanSnapper is what you use when you already have a floor plan — from a previous appraisal, an MLS listing, a builder's PDF, or a Canvas/Apex export — and need to calculate ANSI Z765 GLA from it.

Upload the PDF or image, trace the perimeter, set one known wall length as your scale, and PlanSnapper calculates GLA for each level with above/below grade separation. It is particularly useful for desktop appraisals or when you have a prior sketch that just needs remeasuring.

Which should you choose?
