I have been working with an architect who is a senior project manager with one of the largest architecture firms here in Ga.
He had a question about the accuracy of our camera when we product AutoCAD drawings, so I did a quick study that is worth sharing.
The Church I did recently is a little over 66 feet (20 meters) wide.
Using a 30 foot tape measure I carefully measured from wall to wall.
When I compared the value off ACAD of 20224 mm, the actual measured value was within 6 mm. I estimated the distance to be 20218.
I would put that down as Very Impressive.
I would put the error down to:
- Variations in the building from the point I measure to the point used on ACAD.
- The limitations of using a 30 foot tape measure to measure a 66 foot span
- Baseboards were almost 2 inches think and wooden, so they have natural warp and material/paint variation.
I’ll do some more study, but my initial impression is that this is something we can boast about, if we talk to architects and construction project managers.
That would be an error of 0.03%
