What You’ll Be Creating

Follow this tutorial step-by-step to create a 3D Guitar model that you can use in video games, graphic design and illustration projects whilst learning Cinema 4D quickly. 

Some of the skills you’ll learn in this tutorial include creating basic 3D modelling, importing reference images, adding lighting to the scene and basic rendering techniques.

In this, the first part of the two-part tutorial, I’ll show you:

  • How to Import Reference Images
  • How to Prepare for Modelling
  • How to Model the 3D Guitar

1. How to Import Reference Images

Step 1

Use the middle mouse button to click anywhere on the viewport. This displays all four views. From there, use the middle mouse button to select the Front view.

Four different views

Step 2

In the Attributes tab select Mode > View Settings.

Select view settings from menu

Step 3

In Viewport [Front] select the Back button and click on the button next to Image. 

Select Back and find reference image

Step 4

Select the reference image from the finder and open it.

Open reference guitar image

Step 5

Once the image is displayed in the background of the viewport, change the transparency of the image. This can sometimes make it easier to model from the reference image.

Change the position and size of the reference image from here using Offset X, Offset Y, Size X and Size Y.

Set transparency to 50 percent

2. How to use Splines to Create the Guitar Body

Step 1

To start modelling the body of the guitar, select the Pen Tool from the top menu bar. This allows you to create a spline to outline the shape of the guitar body.

Select the Pen Tool from the top menu bar

Step 2

Use the Pen Tool to draw out the outline of one side of the guitar body. Use the mouse to click and drag to create curves

Step 3

Close the spline by clicking on the first point. 

Close the spline

Step 4

Adjust the shape of the spline by selecting the Point Selection Tool and then using the Move Tool to move the points and handles. 

Adjust the shape of the spline

Step 5

Duplicate the spline once you’re happy with the shape. This is done by clicking and dragging the spline in the list view, whilst holding the CTRL key on the keyboard.

Duplicate the spline

Step 6

Select the Object Tool and then select the Rotate Tool. Select one of the splines that you want to rotate to create the other side of the guitar body.

Select object tool and then rotate tool

Step 7

Rotate one of the splines by 180 degrees. This creates the other half of the guitar body. 

Ensure that the splines overlap in the middle 

Rotate duplicate spline 180 degrees

Step 8

Go to the top menu bar and select Array > Spline Mask

Select spline mask from top menu

Step 9

Select both of the splines that you have created and move them inside the Spline Mask. This will create one whole spline for the guitar body.

Put splines inside spline mask

Step 10

Make the spline mask editable by clicking on the Make Editable button. You won’t be able to make any changes to the previous splines after this, so ensure you’re happy with the shape of the guitar body before committing to this step. 

Click the make editable button

Step 11

From the top menu select Subdivision Surface > Extrude. Then place the spline inside extrude.

Select the extrude button from the top menu

Step 12 

This creates a 3D object out of the shape of the spline.

Extrude the spline

Step 13

Use the extrude object options to adjust the look of the guitar body. 

Change the thickness of the object so that it accurately matches the body of a guitar.

Increase guitar thickness

3. How to Create the Sound Hole 

Step 1

Click on the small back arrow on the Cube button and select Cylinder from the list of options. This spawns a Cylinder in the scene.

Select cylinder from top menu

Step 2

Adjust the properties of the Cylinder so that it is facing the correct way, has the correct size.

Rotate cylinder object

Step 3

Return to the front view to use the reference image as a guide to help with the placement and size of the cylinder object.

Move cylinder object to match reference image

Step 4

Click on the small black arrow in the bottom right corner of the Array Tool in the top menu bar. 

Select Boole from the list. This creates a Boole tool in the list of objects on the right of the screen.

Select boole from top menu bar

Step 5

Select the extrude group and cylinder object from the list and place them inside the Boole Tool. 

Ensure that the cylinder object is positioned below the extrude group.

Place extrude and cylinder inside the boole

Step 6

This creates a cut out in the shape of the cylinder object. 

Adjust the position of the cylinder object using the Move Tool until you’re happy with the appearance of the sound hole.

Create the sound hole

Step 7

Click on the small back arrow on the Cube button and select Tube from the list of options. This spawns a Tube object in the scene.

Select the tube object from the top menu bar

Step 8

Adjust so that inner radius is the same as the radius of the cylinder object (that was used to create the sound hole). 

You’ll also want to adjust the outer radius to a suitable size.

Resize tube object

Step 9

Return to the front view to use the reference image as a guide to help with the placement and size of the tube object. 

Carefully align the tube so that it fits directly on top of the sound hole.

Move tube object to match reference image

Step 10

In the perspective view, use the Move Tool to push the tube further into the body until it’s only just above the object surface. 

Ensure that you use the other views (front, left, right, perspective and so on) to check that the shape looks correct from every angle.

Move tube into position

4. Create the Guitar Neck

Step 1

To start modelling the neck of the Guitar, select the Cube object from the top menu bar. This spawns a cube in the viewport.

Spawn a new cube into scene

Step 2

Use the front view to adjust the shape and size of the cube object so that it matches the reference image. 

Ensure you make the neck slightly longer than needed. This is so that you can make additional adjustments to the top and bottom of the object.

Adjust the cube to look like the neck

Step 3

Check that the neck thickness is appropriate in the perspective view and adjust accordingly using the object properties window or the Scale Tool

Adjust the thickness of the neck

Step 4

In the object properties window, increase the number of Y segments for the fretboard. In this example the guitar neck has 14 Y segments.

Increase the Y segments to fourteen

Step 5

Duplicate the cylinder object that was used to create the sound hole (do this by holding CTRL on the keyboard to click and drag a duplicate object). 

Then place both the new cylinder object and the neck object inside a boole.

Duplicate cylinder and move into boole with neck

Step 6

This cuts out the curve for the sound hole for the neck.

Cut a curve into the neck

5. How to Create the Headstock

Step 1

Create a cube object with two Y segments. Then adjust the size of the cube object so that it becomes a suitable size for the headstock.

Spawn a new cube and adjust to the size of the headstock

Step 2

Make the cube object editable and then use the Edge Selection Tool to move the middle edge closer to the bottom.

Move edge closer to the bottom

Step 3

Use the Edge Selection Tool to select the two bottom corners of the object. 

Then use the Scale Tool to move the edges closer together or close to the neck.

Move corners with the edge selection tool

Step 4

Click on the small back arrow on the Cube button and select Capsule from the list of options. This will spawn a capsule in the scene.

Select capsule from the top menu

Step 5

Move the capsule so that half of it sits within the cube object. Then adjust the size of the capsule to something suitable.

Adjust the size of the capsule

Step 6

Duplicate the capsule and place them both side by side inside the cube object. Group both capsules by selecting them both and pressing Alt-G on the keyboard.

Duplicate the capsule

Step 7

Select Boole by clicking on the small arrow on the bottom right of the Array button at the top of the screen.

Select boole from the top menu

Step 8

Place the capsules and the cube object inside the boole, making sure that the capsules are at the bottom. This will create a cutout of the capsules on the headstock.

Create capsule cutouts

6. How to Create the Tuning Machines

Step 1

Create a new cylinder object and resize it down so that it matches the appropriate size for a tuner. 

Once you are happy with the size, use the Move Tool to move it into position in the headstock.

Step 2

Duplicate the cylinder object by holding CTRL button on the keyboard and then click and drag the cylinder using the Move Tool. Do this twice more so that you’re left with three cylinders.

Duplicate the tuner three times

Step 3

Select all three cylinder objects and duplicate them to the other side of the headstock.

Duplicate the tuner objects on the other side of the headstock

7. How to Create the Bridge and Endpin

Step 1

Create a new cube object and scale it down so that it resembles the size of a guitar bridge. 

Once you are happy with the size, use the Move Tool to move the new cube object inside the body of the guitar so that only the top part of the bridge object is above the surface of the body.
