GroBoto Coordinate Systems:
|Limits/CautionsCluster Size Limit -
A single Boolean Cluster can have a maximum of 32 GroBoto Primitives — attempts to add more should not cause any problems (but we can't be sure), in any case, they will be ignored. Valid Trim Objects -
Only a few GroBoto Primitives are supported as Trim Objects. See Intro & Interface
on this page. We will be expanding the Trim Primitive set (and the ways they can be used), as we go.Textures
- Textures work with Custom Booleans, but you may notice some quirks. Textures do not seamlessly wrap around Boolean Clusters (like they do with simple Primitives), and you may see a big difference in texture scale on the surfaces created by Trim objects. We recommend not using Textures while creating/editing Booleans, the can decrease performance significantly)Bots & Ducts Unsupported
- Boolean Clusters can not be used a Bot Primitives. Likewise, normal GroBoto Primitives that belong to an AutoBot can't be used as Boolean Cluster objects (they can be used once detached from the AutoBot). Ducts are not supported in any form.Flex Tools
- Currently Flex Tool behavior of Clusters (and individual Cluster elements) and is undefined. Upcoming builds will bring Flex functionality to Custom Booleans.
GroBoto treats Boolean Clusters as normal, single primitives (when not being actively edited). Selecting an inactive Cluster automatically selects all of its Primitives, including its hidden Trim objects. Any GroBoto interface item that shows selected object counts reflects those hidden Trims.
Sometimes you want to edit individual Cluster Primitives in an inactive Cluster. We provide two ways of overriding the auto-selecting of all Cluster primitives:
Keyboard Selection - Use Alt-A (instead of the usual ‘a’), with the cursor over the object you wish to select.
Selection Tool - Use Alt-Click with the (make sure the ‘Select Single’ Option is checked in the Edit Panel).
See Active Editing
on this page for additional selection features and notes related to editing Clusters.
'Select By...' Options may not work correctly with Boolean Clusters. (Edit Panel's Select by Group, Select by Type, etc. in - and their keyboard equivalents). For now, please use the ‘a’ key or the Select Tool with the ‘Select Single’ option.
Cluster - A collection of standard GroBoto Primitives that combine to create custom, editable Boolean forms.
Type - Every Cluster consists of two Boolean Object Types:
Primaries - The foundation Primitives that form the maximum extents of the Boolean. A ‘Positive’ form portions of which are removed by intersections with Trim Surfaces.Trim Roles -
Trims - One or more surfaces of a Trim are used (see Trim Roles, below). Portions of the Primaries that fall on one side of those surface(s) are removed.
Which surface(s) of the Trim Object are used, and which side of those surfaces will be retained in the final form (ex. 'Inside Caps'). The Object Context menu (fig. 2), enables only those Roles available with Primitive type you clicked (or, if you have a selection, Roles common to all Primitives in that selection).Active/Inactive -
Cluster Property. Only one Boolean Cluster is Active a time. All of an Active Cluster’s Trim Objects are displayed as wireframes - which may be selected and modified.
Trim objects of Inactive Clusters are hidden - you only see their effect on the Primary Objects. Inactive Boolean Clusters may be selected, moved and rotated like standard GroBoto Primitives.
