SolidWorks how to draw a compression spring?

SolidWorks how to draw a compression spring? SolidWorks Spring Painting has a lot of, but many friends are not clear how to draw, the following to introduce the compression of the spring painting.

1, click the "New" button to create a part file.

2, select the front view datum, click "Sketch", select "Sketch Drawing" button, enter the sketch interface. A circle with a diameter of 22mm is drawn at the center of the original point.

3. Select "Insert"-"curve"-"helix", the Spiral property manager appears on the left side of the sketch interface. Select height and circle in the Define as Drop-down menu, and in the Parameters option, select constant pitch, height input 70, select "Reverse", loop input 7, start angle input 0°, and then create the following helix.

4, hold down the CTRL key, select "Sketch 1" and "Front View Datum", select "Insert"-"derived sketch", generate sketch 2 derivation, the system automatically into the sketch drawing mode.

5. Select "Insert"-"curve"-"helix", the Spiral property manager appears on the left side of the sketch interface. Select "Pitch and Circle" in the "define as" drop-down menu and make the following setting in the "Parameters" option, select "Constant pitch", pitch input 1.62, circle number input 1.5, start angle input 0°, counterclockwise, and determine the following helix.

6, click "Features", select "Reference geometry" in the "Datum plane", select the front datum surface for the reference in the Datum surface property manager to do the following settings. Enter 70 in the distance text, tick "invert", and click OK to complete the creation of Datum 1. Hold down the CTRL key, select "Sketch 1" and "Datum 1", select "Insert"-"derived sketch", generate sketch 3 derivation, and the system automatically enters sketch drawing mode.

7. Select "Insert"-"curve"-"helix", the Spiral property manager appears on the left side of the sketch interface. In the Define as Drop-down menu, select pitch and number of loops. In the "Parameters" option to do the following settings, select "Constant pitch", pitch input 1.62, the number of laps input 1.5, check the reverse checkbox, the starting angle input 0°, select clockwise, determine the following helix generated.

8, select "Insert"-"curve"-"combination curve", in the appearance of the interface, respectively, click on the sketch of the Helix 1, Helix 2, Helix 3. Click OK on the left to generate the combined curve.

9, click "Features", select "Reference geometry" in the "Datum plane", select the sketch point and sideline, generate datum 2. into the sketch drawing interface, with the original point as the center, draw a circle of 1.6mm diameter, exit the sketch drawing.

10, click "Scan", select "Sketch 4" in the outline of scan attribute, the path chooses "combine Curve 1", click OK Complete Scan. As the diagram completes the production of the spring.
