Document Parameters > Document > Performance

Save calculation results of intermediate operations. Enabling of this option speeds up entrance to editing commands of the intermediate operations, but it slows down the total time of recalculation and allocates more RAM.

Saving step. System will store intermediate calculation results not for all operations, but for particular operations with the specified step, e.g. for each 5-th operation.

Maximum number of saved results - maximum number if intermediate operations for which the geometry will be saved.

Save results to model file. Store geometrical data of intermediate operations in file, if these operations have such data at the time of document saving. This parameter may speed up entrance to editing commands of intermediate operations after document opening, but will increase file size and opening time.

Simplify Geometry. Replaces curves at intersections of surfaces by b-splines when recalculating faces. Significantly reduces the size of the document, slightly slows down recalculation.
