Create the Body Profile The bluesurf created in last step is the top surface of the mouse that would fit into your palm. Hide the bluesurf for now. To create the body of the mouse, draw a profile in the x-y plane as shown. |
![t0408 t0408](http://lh3.ggpht.com/-B_Vd-Rht1YE/UqYeCo9aQYI/AAAAAAAABes/ejkH41v8XXE/t0408_thumb.gif?imgmax=800) |

![t0411 t0411](http://lh3.ggpht.com/-din-V7ZqHFw/UqYeJMr8wCI/AAAAAAAABf8/llt6jR5g75c/t0411_thumb.gif?imgmax=800) |
The Replacing Face Then select the bluesurf as the replacing face. Click Finish on the ribbon bar. | ![t0412 t0412](http://lh5.ggpht.com/--qg5OwMQWXs/UqYeKqQgGAI/AAAAAAAABgM/cOzpfgbHaJY/t0412_thumb.gif?imgmax=800) |
Face is Replaced The top flat face of the mouse body is now replaced with the bluesurf. | ![t0413 t0413](http://lh6.ggpht.com/-PCutQQVSSBc/UqYeL9aoSvI/AAAAAAAABgc/BnlqOieu6Eg/t0413_thumb.gif?imgmax=800) |
Mouse Buttons To create the mouse button etching, create a parallel plane to the x-y plane. Sketch a spline on it as shown in figure. Click the Project Curve tool from the Surfacing toolbar. Select the spline as the curve to project. Click accept on the ribbon bar. Select the top face of the mouse body to project the curve onto. Click Finish on the ribbon bar. The spline is projected on the top face of the mouse as shown in figure. |
![t0414 t0414](http://lh3.ggpht.com/-7LyagZ8yq4c/UqYePoxS7JI/AAAAAAAABhM/HBrmPmJToq8/t0414_thumb.gif?imgmax=800) |
Prepare for a Swept Cutout Click the Plane Normal to Curve tool from the Features toolbar. | ![t0416 t0416](http://lh5.ggpht.com/-oCnqS8niZwM/UqYeRFuS4wI/AAAAAAAABhc/miLQTI7NvLw/t0416_thumb.gif?imgmax=800) |
Create a Normal Plane Create a plane at one end of the projected curve as shown. | ![t0415 t0415](http://lh3.ggpht.com/-FkkaYRqRdFE/UqYeSRjTMlI/AAAAAAAABhs/ZFwwKqSJZNA/t0415_thumb.gif?imgmax=800) |
Create the Cross Section Sketch a small circle on the nascent plane. | ![t0417 t0417](http://lh5.ggpht.com/-GkGBh0QOg4A/UqYeT2BzlII/AAAAAAAABh8/aMKlDkQKpts/t0417_thumb.gif?imgmax=800) |
Take a Swept Cutout Create a Swept Cutout using the circle and the projected curve. | ![t0418 t0418](http://lh3.ggpht.com/-q5v2F56a_xM/UqYeWmM2n6I/AAAAAAAABic/l-bAW7GAdFc/t0418_thumb.gif?imgmax=800) |
Its Not All Over Zoom into the area where the swept cutout starts. The cutout has left some material behind where it started. | ![t0419 t0419](http://lh6.ggpht.com/-gnn_d6j3t8w/UqYeX7mgsCI/AAAAAAAABis/oe_V0GuC_Ag/t0419_thumb.gif?imgmax=800) |
Rectification Create a normal cutout again using the same sketch (circle) used for the swept cutout. | ![t0420 t0420](http://lh4.ggpht.com/-NhUS2f6xwCw/UqYeZfHMqeI/AAAAAAAABi8/CEvtnsEffXY/t0420_thumb.gif?imgmax=800) |
This Looks Better | ![t0421 t0421](http://lh3.ggpht.com/-WAHX37VKJ7E/UqYebKj0pQI/AAAAAAAABjM/D53cqdrrb6g/t0421_thumb.gif?imgmax=800) |
Same Story on Far Side On the other side, where the swept cutout ends, the case is similar. But there is no sketch (circle) to take the normal cutout and to extend the swept cutout far outside the mouse body. We need to create a curve to take the cut. |
![t0422 t0422](http://lh4.ggpht.com/-xOMFHS7gjwg/UqYecvQrDdI/AAAAAAAABjc/AGHNlMwCvuM/t0422_thumb.gif?imgmax=800) |
Derive a Curve Click the Derived Curve tool from the Surfacing toolbar. Select the edge of the swept cutout. Click accept on the ribbon bar. |
![t0423 t0423](http://lh6.ggpht.com/-1T4vaIXRNY0/UqYehLJDK_I/AAAAAAAABkM/jnWCFQu8TKA/t0423_thumb.gif?imgmax=800) |
Curve is Derived The edge is derived as a curve. See figure. Using this curve, take a normal cutout and extend the swept cut, outside the mouse body. | ![t0424 t0424](http://lh4.ggpht.com/-so5gZxVF71Q/UqYeig1ndLI/AAAAAAAABkY/2bZlSVLEm-s/t0424_thumb.gif?imgmax=800) |
Make the Buttons Similarly, take two more swept cutouts to make three buttons. | ![t0425 t0425](http://lh4.ggpht.com/-i7MpzJKymmg/UqYejpsnqXI/AAAAAAAABks/oBcGg0t6cx4/t0425_thumb.gif?imgmax=800) |
Merge the Cutouts Also extend the cutouts for the mouse button separations where they meet the previous swept cutout. | ![t0426 t0426](http://lh3.ggpht.com/-2pEIXduSZ_I/UqYek_eReHI/AAAAAAAABk8/I_wIc_8U3Pk/t0426_thumb.gif?imgmax=800) |
Aesthetics, etc. Round the sharp edges at the base and top to give the mouse more aesthetic looks, etc. Latest offerings from www.CADVertex.com | ![t0427 t0427](http://lh3.ggpht.com/-EaomKK81owk/UqYem8gtP2I/AAAAAAAABlU/11SuseNqosM/t0427_thumb.gif?imgmax=800) |
