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! - 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

make! - 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. Tips! Rename the object to its final name before making it a component (in outliner or with right click and entity info).

Rotate Object(s)

degrees around red, green or blue axis! (select object(s) first). Very handy for objects with curved surfaces like pipes, elbows ..

Move or Copy Object(s)

move/copy! no. copies red green blue (offset from current position
- 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.

The Knife

- inserts a "Knife" to cut in one or more objects.

insert the Knife! size of 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 another Objects Position

move! - select two objects - then click "move" and one of the objects moves to the position and angle of the other object. Handy when moving between axis systems.

Change Insertion Point

You can change the position and angle of an inserting object by pre-selecting an existing object before Insert! The inserted object will inherit the position of the selected object. Handy when working with non-default axis.

Insert Line

red green blue - Start position
red green blue - End position

insert! - use this feature to add a reference line

Insert Horizontal Plane

insert! red (size) green (size) blue (vertical position)
- use this feature to add a horizontal reference plane

Insert Vertical Plane

insert! red (horizontal position) green (size) blue (vertical size)

insert! red (size) green (horizontal position) blue (vertical size)
- use this feature to add vertical a reference plane

Insert Box

insert! red (width) green (depth) blue (height)
- use this feature to add a box to the model

Insert external Component

insert! name url
- use this feature to add an external .skp component from the internet by adding the component url
