Julia Christina Eneroth has developed Eneroth Solid Tools (Pro Only). This skethup plugin combines different types of tools like solids union, subtract and trim. The plugin is compatible with SketchUp 2014, SketchUp 2015, SketchUp 2016, SketchUp 2017, SketchUp 2018. It can be used for 3d printing, drawing and productivity.
Union: Attach one solid group or component to another.
Subtract: Subtract one solid group or component from another.
Trim: Trim away one solid group or component from another.
When you activate the tools with two or more solids chosen, the plugin assumes the largest one as the primary (the one to retain but rectified) and the lesser one refers to the secondary ones that defines how the primary one is rectified.
If the tool is turned on with no selection you’ll be requested to click each solid, initially the primary one and then any number of secondary ones applied to rectify it.
The primary solid will retain its layer, material, attributes as well as ruby variables indicating at it unlike how native solid tools function. Layers and attributes of entities within both of the solids will also be maintained.
