MagicaCSG Beta 0.5.0: Subgrouped Boolean

Subgroup

• You can group/ungroup the strokes via the stroke list menu.

• You can also group groups of strokes (up to 4 levels).

• Select/Transform/Duplicate/Delete/Hide a group will be applied to all the grouped strokes.

• The group has its own Boolean mode and blending options (blending factor, chamfer, opacity, etc.), which treats the grouped strokes as a compound stroke.

• Boolean operations within a group are localized and won't affect the strokes outside the group.

Collapsed Subgroups

• You can click the arrows besides the subgroups in the list to close/open a subgroup.

• When a subgroup is open and you click a stroke within it, the clicked stroke will be selected.

• Once the subgroup is collapsed and you click a stroke within it, the collapsed subgroup will be selected. In this way, you are able to transform/duplicate the subgroup as a single opaque primitive.

• You can double click the subgroup name to select all strokes within the group. You can close/open all subgroups using the right-click menu.

Dragging and Dropping in the Stroke List

• You can move strokes around by pressing one of the selected strokes, and then drag and drop them to another location in the stroke list.

• You can move one or multiple strokes/groups all together, and they can belong to different groups or group levels.

• When dropping the strokes, you can determine at which group level you want to insert the moved strokes. (The group level is indicated by a bar cursor). This is very handy when inserting the strokes at the end of a group, because the end location may belong to multiple nested groups.

• The arrow key ↑↓ in the list menu can only move strokes within the same group.

• Enabling the insert key ⓧ in the list menu allows you to insert the new added strokes after the active strokes within the same group, instead of appending strokes at the end of list.

Limitations

• Subgroups and Sweep Modes require more buffer space than basic strokes (depending on the depth of nested groups, and the number of control points).

  If the strokes can't be generated correctly, maybe there are too many nested subgroups or control points in a sweep spline. Try to separate the strokes into objects.

• Subgrouped strokes don't always have accurate sdfs, especially in the interior region.

  Therefore, when you subtract a stroke from a subgroup of strokes, you may notice some unexpected artifacts.

  (But it's fine when you use a subgroup of union combined strokes to subtract other strokes)

• The maximum allowed nested group levels is 4.

  In current ui, when you drag and drop a subgroup to another subgroup, if it exceeds the max levels, then no strokes will be inserted by your "drop" action, so the dragged strokes are simply removed. You can use Undo to recover that.  

• There is no way to duplicate an empty group using gizmo.

• Groups don't have color/material properties. The color/material of surface is defined by the strokes within the group.
