Rotation steps

A rotation step is not really an LPub3D feature, but can be used in building instructions to display one or more steps from a different angle. An example of this can be fund on page 8 step 11 of the official instructions for set 40252.

You can add a rotation step in LPub3D (which can be complex and difficult), but also in your LDraw editor like LDCad.

  • Download and open an LDraw file that has the rotation step for this step and navigate to page 6

  • Note the meta command at line 42 of the code: 0 ROTSTEP 180 0 0 REL

  • This tells LPub3D to rotate the model 180 degrees around the x-axle in 3D space relative to the the rotation matrix. The page should look something like this:

  • Now right click the assembly image of step 6 and choose <Add Rotate Icon>

  • Right click the border of the just added rotate icon and choose <Change Rotate Icon Background>

  • Change the background to <Solid Color> and make it white

  • Click [OK] and make it a global setting by choosing [No] when asked to change only this step

  • Right click the rotate icon and choose <Change Rotate Icon Placement> and choose Relative to <Step Number> and click the [Bottom:Left] button and then [OK]

The result should look something like this:

Note the meta command now at line 48 that says 0 ROTSTEP END

This tells LPub3D to end the rotation step and draw the assembly images from this point like normal.


    • Now go to the next page, add the next step and a divider

    • Right click the assembly image of step 7 and add another rotation icon

    • The placement of this icon can be set relative to the [Left:Center] the assembly as there is no room for placement under the step number.

    • Save your work.
