Create Hole

In this Task 

Points will be arrayed on the front surface of the model onto which holes will be inserted.

The holes will automatically subtract material from the primary solid.

Associated Tasks 

Workplane by Facet / Auto Workplane by Face.

Inserting a Point.

Creating a Radial Copy of the Point.

Before you Start 

View is set to Isometric South East.

Workplane is set to Plane by World.

Remove the display of the Form Building Edges GDI Mode only. Options | Native Draw | GDIForm Building Edges for clarity. Use Options | Display | Form Building Edges to control the display of surface lines and edges.

Add Holes

Ribbon : Modify | 3D Modifications | Add Holes

Default Menu : Modify | Modify 3D Object | Holes

Palette : 3D Model | 3D Object | Add Holes

This tool allows the creation of a predefined hole which automatically adds or subtracts the hole material from a solid.A point is used to place a single or multiple hole.

Use Workplane by Facet to place the Workplane on the front face shown below.

Make sure to view the model from different viewpoints to check the position of the Workplane.

Next, insert a Circle Sketch | Circle/Ellipse | Circle Center & Point using the Nearest snap point on the construction line as the center point, shown below left. Input a radius of 96 so that circle is shown similar to the illustration below right.

Take Note

The Nearest point on the construction line was used as a guide. The circle will be placed on the current Workplane.

Select the nearest point (above left) as the center of the circle. Circle radius is 96 shown above right

The newly drawn circle is shown below from the Right side view.

Point

Ribbon : Draw | Draw 2D | Point | Cross

Default Menu : Draw | Point | Cross

Palette : Sketch | Point | Cross

This tool is useful for marking centers of arcs and circles prior to dimensioning.The overall length of the Point markers can be adjusted using the Selection Info palette.

Right click onto the Point (cross) tool using the menu options above and select the Point page. Select the Cross option, then set the size to approximately 15. Click OK.

Left click onto the Point tool and input the first point on the quadrant point of the circle shown below. Input Q to target the quadrant if snaps are deactivated.

Select the newly inserted Point marker, then use the Radial Copy tool to create a total of 6 copies of this point, copied and rotated at 60º shown below.  Use the center of the newly drawn circle as the center of the array.

The result is shown below.

Right click onto the Add Holes tool shown top and select the Hole page. Apply the settings shown below. Click OK.

Applying the hole settings

Left click onto the Add Hole tool and select the planar face upon which the holes should be generated, in this case, the front fact shown in green below.

Select the first point, then hold down the SHIFT key to select the additional 5, shown below.  Make sure the point is selected where it intersects the circle.

Select Finish. The result is shown below.
