Tips/Tricks-3dsmax: The Shell modifier is better than Extrude

Yes, you can use the Shell modifier on splines.

Many normally don’t think of using the Shell Modifier with splines… usually the Shell Modifier is added to a series of faces to add “thickness” to already established polygons.

When it comes to splines most people go for the Extrude Modifier first. Few realize the Shell Modifier will also serve the same purpose but with added functionality.

Like the Extrude Modifier, the Shell Modifier also converts the spline into a 3D solid object and extrudes a series of faces up. But unlike the Extrude modifier, you can extrude faces in both directions simultaneously (up and down).

What’s more, you can add material ID settings to the top, bottom, and edge polygons directly from the modifier.

And finally, what may be the coups de grâce, you can control the edge profile with another spline– just like the Bevel Modifier. So the Shell Modifier is really a combination of Extrude and Bevel Profile.

  1. Hi,

    I’m a total 3DS Max, but i’m trying to help a charity make their logo in 3d, i’ve got the various shapes in AI format, and have imported into 3DSMax, when I extrude/shell/bevel the ‘C’ shape spline breaks down into faces as opposed to a smooth side, how can i get around this?

  2. Fixed it, when using shell on a curve, you need to adjust the interpolation by selecting the spline before applying the effect…

  3. Hi, thanks for this comment 🙂
