To profile and extrude multiple loops

This time we will draw using Mechanical Desktop program with multiple profiles at once to Extrude it.

1. Choose Design > Rectangle, and a draw a rectangle in the graphics area.

2. Choose Design > Circle > 2 Points, and draw three circles inside the rectangle. Make sure that none of the circles overlap or touch each other.

3. In the graphics area, right-click and choose Sketch Solving > Profile.
4. Using the small rectangular cursor, select the rectangle and three circles by dragging a box across them until all are highlighted.
5. Press ENTER. The rectangle and all three circles are profiled.

6. In the graphics area, right-click and choose Sketched Work Features > Extrude.
7. In the Extrusion Feature dialog box,

• Operation: Base
  
• Distance: 60
• Draft Angle: 0
  
• Termination; Type: Blind
• Choose OK

8. Press ENTER to accept the default direction of the arrow.
9. To see whether all three circles extruded simultaneously, choose View > 3D Views > Left Isometric.

Creating and Extrude Profile

For those of you who just learned to draw using Mechanical Desktop, here I will give basic examples of drawing part / 3-dimensional components. Hopefully this will help you to see more of the application of this program. And in this case, I will make a 3-dimensional image of a rectangle with a 3mm high.

The first step is to create a sketch profile (profile a sketch). Select Design > Rectangle, and create a rectangle on the graph image area (for the length and width dimensions as you ignore the past, Insha Allah in the next example I will give).



After that the graphics area, kick-right and select the Sketch Solving > Single Profile. The purpose of this command is to convert the sketch into a profile that is ready for in-Extrude,



to appear dotted line as an example the following image. And the rectangle has now become a profile.



Then in the graph area, right-click and select Work Sketched Features> Extrude.

In the dialog box Feature Extrusion, specify:

• Operation: Base

• Distance: 3

• Draft Angle: 0

• Termination Type: Blind

• Choose OK.

Press ENTER to accept the above results in the direction of the arrow. To view the isometric drawings, select View > 3D Views > Left Isometric.

To Create a Sketch

For this procedure, you use a polyline and an arc to create a sketch similar to the one shown above. Make sure you are working in the Assembly Modeling environment by choosing the Model tab in the Browser. If the Browser is not displayed, choose View > Display > Desktop Browser.



1. Choose Design > Polyline.
2. In the graphics area, click a start point for the sketch. Continue to click from point to point, forming the shape, until you reach the arc. Each time you click a point, you are prompted to specify the next point.



3. To draw the arc,
- Keeping the cursor in place in the drawing, enter a on the command line to create the arc, and then press ENTER.
- On the command line, enter d, and press ENTER again.
- Click the direction for the arc.

- Click the endpoint to complete the arc.

4. Keeping the cursor in place, enter l (Line) on the command line, and then press ENTER. Resume sketching until you reach the last point before the sketch is closed.
5. Keeping the cursor in place, enter c (Close) on the command line, and then press ENTER. This closes the sketch.

Good try!
