Interface overview

You can organize your design into steps, just like the steps in LEGO set instructions.

1. Model Menu: each submodel has its own steps. Use this box to choose which submodel is displayed in the Viewport and Step List.
2. Search Box: filter parts and submodels in steps.
3. Steps: shows all steps in a design. Each step is numbered and can also be named.
4. Create Step:
   • If a step is selected, a new one will be created after the one you’ve selected.
   • If a part is selected, a new step will be created as the last step.
5. Steps Toolbar: there are more buttons at the bottom of the step list.
6. Step View: switch to Step View mode, in which the model is shown as instructions.

Step options

You can expand/collapse a step by clicking the button on the left side of it. Changing descriptions or deleting a step is available using buttons that appear when you hover over it.

1. Collapse / Expand: when a step is expanded, parts and submodels are displayed in the step list so you can manage them. If a step is collapsed, only its number and name are displayed in the step list.
2. Description: add a description for a step. It can come in handy to easily identify a step.
3. Delete: remove a step. The contents will be moved to the following step.

Steps toolbar

There are more buttons at the bottom of the step list.

2. Expand All: all steps, parts and nested submodels will be displayed in the step list.
3. Hide: Allows to hide the currently selected items in the Viewport.
   • If parts are selected, those parts are hidden.

   • You can select multiple parts and steps or a combination of both by holding the Ctrl key while clicking on them.
4. Create: same as Create Step (D).
