n this chapter, we’ll trace a pencil sketch to
make a dashboard mount for a phone.
Despite the project’s complexity, we will take a
loose approach because that emphasizes working
through a prototype idea in your head. This is
useful for the conceptual phase of product design.
Our intent is to generate a concept model, and for
this purpose, it doesn’t have to be a finished,
perfect product. Set the dimensions to mm and
click the View Cube’s dropdown arrow to make
the workspace orthographic (Figure
A
).
Hand Sketch an Idea
Do a web search for your phone’s dimensions, and
hand-sketch an idea for a mount. The proportional
accuracy of the sketch is important because
we’ll be tracing it. So, use a ruler or grid paper.
Figure
B
shows orthographic (2D) sketches
for a design. It consists of a stand and clip that
are held together with a socket and ball joint.
The dimensions are in mm, and I added 2mm
to height and width dimensions to allow space
for the phone to fit inside the clip. You can type
all needed dimensions as you work, or you can
simply trace the sketch, adding a few dimensions
here and there, and scale it all correctly at the

end. That’s what we’ll do. Know that the dimensions I use may not be exactly
what you need, due to the differences in your own sketch.
Import the Hand Sketch
To bring the sketch into the workspace, click Insert →Canvas/Insert from
my computer, navigate to the sketch and click on the horizontal origin plane
(Figure
C
). The sketch, a transformer, and a dialog box will appear (Figure
D
). Note the Canvas Opacity field is at 50%. This means the canvas will be
translucent, which is useful when tracing over it (sometimes sketches get
hidden under the canvas). A 100% opacity would mean you can’t see through
the canvas at all. You can also flip the direction of the sketch. I rotated it but
kept it at the origin, where it imported. Click OK to finish.
You can only import a canvas level with the origin. If you want to place the
canvas above the origin, offset a construction plane and attach the canvas to
Tip: If you want to
use my sketch, take
a photo of it and use
that as the file. Scale
it after import so that
it matches its written
dimensions when
you click the Inspect
→Measure tool on it as
closely as possible.

that plane upon import. You can also attach a canvas to an existing body. If
you need to move the canvas later, select the canvas by right-clicking its
Browser entry and choose Edit Canvas (Figure
E
). A transformer to move it
along the x and y axes will appear.
Model the Clip
The clip has three parts: a bracket that holds the phone, a ball joint, and a
stem that holds the ball joint and bracket together. Click on the View Cube’s
top plane and click the arrows as needed to position the sketch right-side-up
(Figure
F
).
TRACE AND COPY THE BRACKET
Start the clip by entering sketch mode and drawing two concentric circles,
.75mm and 1.5mm, as shown in Figure
G
. To copy them, the sketches must
be in Edit mode, so if you clicked Finish Sketch after drawing them, draw a
window around them to select, right-click and choose Edit Sketch (Figure
H
).
To copy, drag a window around the circles again, right-click one and choose
Copy (Figure
I
). Click the mouse onto the workspace, and then right-click

and choose Paste (Figure
J
). Arrows will appear
over the circles; drag the copy to the bottom of the
sketch (Figure
K
).
Next, draw two vertical lines connecting the pairs
of circles, inferring their start and endpoints
from the circles’ centers (Figure
L
). Make sure
the lines are tangent to (touch) the circles. Faces
should appear between all lines.
EDIT THE BRACKET CIRCLE
SKETCHES
While still in Edit mode, select and delete the
dimension lines. Draw horizontal construction
lines through the circles’ centers to serve as
trim lines. If you hover over the center point and
then move the mouse to the side before drawing,
you’ll ensure the line goes through the center
and is horizontal. With Modify →Trim, remove the
bottom half of the top circle (Figure
M
) and the
top half of the bottom circle, overlapping circle/
vertical line segments, delete the construction
lines, and draw end lines to close the shape.
