Beginners Guide to Modelling an Acoustic Guitar in 3ds Max – Part 2


Creating the bottom ridgePlace the newly created box just above the Rosette, this box would be used as the top board of the guitar neck.

The top board of the neck consist of a different composition of wood than the bottom part of the neck. to start modelling the bottom part of the neck create a box object and by using box modelling extrude it to a shape as below.

Extrude out the faces up until the head of the top board so that there is plentiful room to model the head of the guitar.

Once the low polygonal model of the bottom neck is completed apply a Turbosmooth Modifier
on the neck of the guitar to smooth out the result.

To model the head start extruding out the bottom board neck and notice how the head curves down in shape when viewed from the left perspective.

Once the entire neck and head is created it looks as below. I have curved the top of the head section like in Gibson guitars.

Extruding the bottom ridge

Modelling a guitar Fret

Start off with a box placed on top of the first segment on the top board of the neck. By use of the Taper Modifier we could curve in the edges of the fret inwards to model a low polygon fret. Since a fret is a small part of the guitar it would be fine to keep it remaining as a low polygon object.

3ds max consisted of Cloning methods that easily allow to replicate the fret that we have created.

There are several ways to clone and object in 3ds max. Once of the simplest ways clone is to hold down Shift and to move the fret to the next immediate segment in the neck.

Modelling the Head

When releasing the Shift key after moving the Fret brings the dialog above, this allows to set the number of cloned elements. The clone type refers how the cloned objects co-relate to the original source object. In a case where Instance is selected the cloned objects would mimic any property changed in the base source object.

Creating the Bridge

Create the bridge by again starting off with a simple box model and out-lining and enhancing it by building on top of it.
The images below show how the bridge has been detailed. Double extrusions and outlining is done to create the ridge on top of the bridge. and a separate string resting piece has been added separately.

Completed neck and the head of the guitarCreating the Strings

The strings need not be created again separately. Since we were able to properly define the segments in the neck its easier to extract them out to create string splines.

Navigate to the sub-object Edge level in the top board of the guitar and select the length segments through to the head as a single line. Next go to the Edit Polygon section and select Detach Edge and clone the edge to a new object spline. Do the following to all the 6 strings.

Using Spline modelling techniques to create the End pin

The end pin is a symmetrical revolved edge. To model such objects 3ds max consists of a special modifier knows as Lathe .
Start off by creating a cross section of the model intended to be revolved using a spline object as shown below.

Apply a Lathe modifier to the model. Provide the proper axis and weld any vertices than stick out. Make sure that face normals appear correctly in the model if not flip them to correct it.

The bridge pins also can be created using a cross section and later revolving using a Lathe modifier.

Start creating the tuning keys using basic shapes.Cylinders stack one on top of the other can easily model the above
