You can change the shape or position of 2D Takeoff geometry. You can also add and remove vertices, or delete pieces of geometry from your takeoff. To help you manage complex, multiple takeoffs you can show and hide individual takeoff markups to make viewing easier.
Scale can also be altered for individual 2D sheets. You can match the known scale of an original model, or create a custom scale to suit your project. Just measure a length of geometry, and then transpose the length from the model to calculate an average scale.
