# Bolt Calculation

The bolt calculation function replaces the way Plant 3D creates bolt sets. Besides BoltSets you can also create single bolt parts like bolt, nuts, washers.

The Bolt Calculation is a complex feature. Not so much in regards of using it, but in regards of the possibilities of understanding the workflows and adapting the catalog, iso style and reports.

Therefore we recommend watching the videos in the order of the sub chapters.
