Tools - accessed from within Sketchup

NOTE!! - the insert! and the Tools features only works when the engineeringtoolbox exension is opened from within SketchUp. Install the extension as described in the right column - restart Sketchup and open this tool from the Sketchup Plugins menu.


undo!   redo!


  change color!

Change color of the selected object(s) - may be slow for some more complicated objects (save your model first!)


iso!   top!   front!   right!   left!   back!   bottom!

Make Component


Makes a component of the selected object. Note that all objects from the Engineering Toolbox are inserted as individual groups. You should transfer a group to a component sharing the same definition when there is more than one instance of the same object. Tip! Rename the object to its final name before making it a component (in outliner or with right click and entity info).

Rotate Object(s)

around red!  , green!   or blue!   axis.

Select object(s) first. This tool may be very handy for objects with curved surfaces like pipes, elbows and so on.

Move or Copy Object(s)


Move or copy (multiple) selected objects. Make advanced geometric constructions with multiple selections, multiple copies and the offset. Tip! - Use "Make Component" to save space and reduce computer load when working with multiple copies.


insert the Knife!   cut!

Before cut - customize the inserted Knife! The Knife is a group you can rotate, change the size of, and even add or remove objects within (example - add a function curve for an advanced cut). You can also make your own Knife by naming a group "theKnife". After insert and customizing the knife - positioning it to the object(s) where to cut - select the object(s) (must be groups) - and click cut! Afterwards - select the object(s) and remove the parts of the object(s) that you don't want. YouTube demo of the Knife!

Move an Object to an other Objects Position


Select two objects - click "move" - and one of the objects moves to the position and angle of the other object. This tool may be handy when moving objects between axis systems.
