Spline Combiner: Rainbow Logo Tutorial

Hi guys!

In this tutorial we want to show you how to cut 2D shapes in 3ds Max, in a clean and easy way, using the Shape Cutter tool from Spline Combiner 3dsMax script to make the logo in the image above.

In the case of this 3D logo, the three different color regions were required to be separate meshes, to animate them independently.

3ds Max natively comes with a tool for cutting 3D objects called ProCutter (located in Control Panel > GeometryCompound Objects). You could use this tool to cut an already extruded logo, but that way you end up with an Editable Mesh (or Poly) with a collapsed modifiers stack. You loose the advantage of keeping the extrusion parametric as a modifier.
Using this script, you work in a non-destructive way, so you can go back and edit the original shapes/splines if you need to.

Let’s start. Make a new scene in 3ds Max and do the following:

1. With the Text shape tool, type “Rainbow” (or whatever you like) in a viewport, give the text a reasonable size and assign a nice font to it.

2. Draw an arc through the whole word. Then make a copy, using SHIFT+move, and place it below it to build a rainbow arc, like in the first step at the image below.

 

3. Open Spline Combiner.

4. First, you need to attach both arcs together because Spline Combiner requires the cutter object to be a single shape. So, select both arcs. Then go to the Tools rollout (in the script’s UI) and press Attach Selected. Now you have a single shape containing both splines.

5. Go to the Shape Cutter rollout. Press the button  Pick Cutter Object and click on the arc shape. Its name appears in the button text.

6. Leave all the checkboxes on. The options Cookie cut for closed shapes and Detach all elements are exactly what we need to get extrusion-friendly shapes.

7. Select both shapes, the rainbow arc and the text. The press APPLY CUTTER.

8. The script will take a little time to perform the action. As a result, you will get many single spline shapes (3 or more per each letter). Like in the 2nd step at the above image.

9. Now you need to attach all the shapes by region, considering the 3 regions delimited by the arc shape: top region, middle region and bottom region. So, select all the shapes in the top region, go to the Tools rollout again and press Attach Selected. Repeat the same procedure for the shapes in each region. You will end up with only 3 shapes, like in the 3rd step in the image above.

10. At this point you can delete the cutter object. Delete the arc shape then.

11. Now try to assign an Extrude modifier to the top shape of the logo. If the shape does not extrude well, it means there are some open splines. You need to weld all the vertices properly to get closed splines for the extrusion. So, at the Tools rollout, use the Weld Vertices tool for that. Repeat the process with the other shapes if necessary.

12. To make a 3D logo from a vector shape, you can use either the Extrude or the Bevel modifier. The one in this tutorial was made with Bevel.

13. You should have a now a beautiful 3D logo, composed of 3 meshes. Assign a different colored material to each one and you are ready!

We hope you enjoyed making this practice. If you have any doubts or consultations, you can post a comment down here or write us through the Contact Form.
