Tutorial  Non-Circular Cutout

In order to make a non-circular cutout, it is important to understand the sketcher tools. A list of all the tools available and a description of what they do is attached below.

1)Create a part by double click Parts in the model tree
Choose 2D Planar, Deformable, Shell, Approximate Size = 20
Click Continue
The sketcher mode is now open. The sketcher tools are now on the left of the viewer window and available for use.

2)Create the external boundary of the part using the rectangle tool (select corner points as (-10,-5) and (5,5) ).

3)For this example we will make the following internal cutout shape:


*NOTE*The internal geometry can not overlap the external geometry.

4)Using the Create Isolated Point tool , place points at

(0,3)

(10,-3)

(-6,-3)

(-6,-2)

(-6, 3)

(-6,2)

(-7,-2)

(-7,2)

5)Connect the points using the Create Lines: Connected tool on the top, left and bottom, leaving the right side open

6)Create the semi-circle end by either using the Create Arc: Center and Two Points tool

7)Click Doneat the bottom of the sketcher window.
The final result will look like the following:

/ Create Isolated Point: allows user to create a point in any location in the sketch area / / Create Lines: Connected: allows user to create lines by connecting points
/ Create Circle: Center and Perimeter: allows user to create a circle by first selecting the center point of the circle, and then selecting a point that will determine the radius of the circle / / Create Lines: Rectangle: allows user to create a rectangle by selecting the top left and bottom right points of the rectangle
/ Create Ellipse: Center and Perimeter: allows user to create an ellipse by first selecting the center of the ellipse, and then selecting two points on the curve of the ellipse / / Create Arc: Tangent to Adjacent Curve: allows user to create an arc by first selecting a point on a line or curve, and then selecting the end point of the arc
/ Create Arc: Center and Two Points: allows user to create an arc by first selecting the center point, then selecting the start point of the arc, and finally selecting the end point where the arc will end / / Create Arc: Through 3 points: allows user to create an arc by selecting 3 points on the arc
/ Create Fillet: allows user to create a fillet by first typing the fillet radius, and then selecting the two lines to fillet / / Create Spline: Through Points: allows user to create a spline by connecting points
/ Create Construction: allows user to create construction lines. Construction lines are only guidelines and are not part edges. By clicking and holding on the button more types of guideline options will appear. / / Create Dimension: allows user to dimension an object. By clicking and holding on the button, several more types of dimension tools are available.
/ Edit Dimension Value: allows user to edit the value of the dimension / / Edit Vertex Location: allows user to edit the vertex location
/ Auto Trim: allows user to trim sections of a sketch. The trim will trim from point to point, while the delete tool deletes the entire entity. / / Project Edges
/ Copy Entities: allows user to copy a part of a sketch, and then translate, scale, rotate, or mirror the pasted object / / Offset Curves: allows user to take a curve and create a curve with the same shape but offset a specified distance
/ Linear Pattern: allows user to create a linear pattern of a section of a sketch / / Radial Pattern: allows user to create a radial pattern of a section of a sketch
/ Undo/Redo: allows user to undo or redo their last action / / Delete Entities: allows user to click on items in order to delete them
/ Add Sketch: allows user to bring a saved sketch to work area / / Save Sketch As: saves a sketch for later use
