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.
