Each page in a plan set comes with its own scale. So, to measure accurately, you should scale each one.
ProCalc offers scales of:
- 1:200
- 1:100
- 1:50
- 1:20, &
- Custom Scale
Select “custom scale” from the scale drop down menu when plans are scaled unusually or you’re not 100% sure.
The plans will need to have both horizontal and vertical dimensions that you can use to create a custom scale – just follow the prompts.
If, after doing all this, you still can’t determine the scale, you’ll need to:
(a) print the page and apply a scaled ruler until you find the scale, or
(b) reach out to the plan’s author and ask them what scale should be applied.
Please note: once you scale the plans and move on to the next variable, the original page scale will be locked and cannot be changed. To progress, you will need to start a new estimate and reload the plans.
