In this blog, I would like to use Solidworks to create a simple cat mask of A Whisker Away. This blog will be divided by two parts. 

      1. Shape of cat mask 

      2. Details on cat mask 

1. Shape of cat mask 

First, use sketch picture to place the front view and side view on front plane and right plane respectively. Then, open new sketches on front and right plane and draw the outline of mask.

Use surface tool-“Boundary Surface” to create a surface between sketches. You may add “Normal to profile” on start and end constraints.

You may need to adjust the shape of cat mask. You can use trim surface tool in surface tab. For example, you want to adjust the side view of mask. You can open a new sketch on right plane and use spline tool to indicate positions need to trim. Then, use trim surface tool .

(Type: standard, trim tool: sketch, Remove selections> select the surface to remove).

Use “Thicken” feature to add thickness to the surface. Then, use fillet to smooth out the edge of mask.

Then, you can start to make the ear of mask. First, open a new sketch on front plane and draw the outline of ear. Then, use extrude boss to extrude the sketch. Then, use move body to move the ear to suitable position and use combine feature to combine the face and ear to one solid body. Finally, add fillets and use delete face tool to smooth out the transition

between the ear and face.

2. Details on cat mask

First, open a new sketch on the front plane and draw the outline of eye and use extrude cut to cut eye shape.

There are two ways to make other details on mask. You can use split line feature to project the sketch on the face of mask. The face of mask will be split so you can apply different appearances on the face.

The second method is to use projected curve feature to project the sketch on the face of mask.  The sketch on mask will be used as a path for sweep feature. Then, use sweep feature to make the details into 3D. Repeat same steps for cat ears. Finally, use mirror feature (Remember to use Body to mirror tab) to get whole cat mask. The cat mask is finished.
