Geometry Creation TASK 1: SETTING THE ENVIRONMENT Before starting the geometry creation you should set up the grid, toolbars and machine type as outlined in the Setting the environment section at the beginning of this text: 1. Set up the Grid. This will help identify the location of the origin. 2. Customize the toolbars to machine a 2D part. 3. Set the machine type to a Haas Vertical Spindle CNC machine.

TASK 2: CREATE A RECTANGLE 3 X 3 – THE CENTRE IS AT X0 Y0. Â This task explains how to create the 3 square. These four lines could be created in many different ways, this is just one option. 1. Select from the pull down menu Create>Rectangle…

2. The Create Rectangle ribbon bar appears and you are prompted to Select position of base point, or Select position of first corner

3. On the ribbon bar click in the space for Width and enter a value of 3.0, hit the tab key and you will be moved over to the Height section.

4. In the Height section enter a value of 3.0 and then hit Enter. 5. Select the Anchor to Center option - this option is shown above. To activate the Anchor to Center option the icon is pressed down as shown above. Anchor to center: Sets the base point of the rectangle to the center point, and draws the rectangle outward from the center.

8. You are prompted to Mirror: select entities to mirror. Â Now you need to select the four circles on the screen. We could accomplish this by selecting each one as we did in the previous mirror operation, but for this mirror operation you will explore another method utilizing the General selection ribbon bar to capture the four circles for the mirror operation. General selection ribbon bar Use the General selection ribbon bar to select entities in the graphics window for most Mastercam functions. Mastercam's selection mode is always active when you are not using a function such as creating geometry or analysing an entity.

9. The General selection ribbon bar is shown below. Open up the drop down for Entity Selection settings to review the various options and ensure it is set to In before leaving.

Entity selection settings Determines how the polygon and window selection methods select entities: In - Selects only entities that lie completely inside the window. Out - Selects only entities that lie completely outside the window. In + - Selects entities that lie completely inside and entities that intersect the window. Out + - Selects entities that lie completely outside and entities that intersect the window. Intersect - Selects only entities that intersect the window.
