Bolts

Bolts are one type of fixture that can be used to fix your connection to your member. Bolts first have to be specified, before they can be referenced in the parent fixture or child fixture sections. Once they are defined, they are referenced by their ID.

Clicking the ‘Bolts’ button will bring up the summary table to define your bolts. You are able to define as many bolts as you wish, and reference them by their ‘Fixture ID’. The table summarises all the bolts you have defined. You are able to add new bolts with the ‘Add’ button, edit a bolt with the icon in the ‘Edit’ column, delete a bolt with the icon in the ‘Delete’ column, and delete all your bolts with the ‘Delete All’ button.
