Socket Screws

Draw screws in plan and side view.

This function allows you to draw a predefined screw, or specify and create a new screw definition.

The Mechanical Setup option defines the default line styles and pens to use.

Make sure that the drawing units are set to "mm" (millimetres) before using the mechanical toolkit functions.

Procedure

1. The Socket Screw settings display.

2. Select a predefined screw from the drop-down list, or fill in the relevant data.

3. Select whether to draw the top view, the side view, or both.

4. Select the line type (solid or hidden) to use for the head and shaft.

5. Click OK to draw the specified screw.

6. You are prompted to:

Indicate the position of the Screw side view

7. Position the cursor where the screw must be drawn and then click. The hook point is at the base of the head of the screw, as shown below.

8. If you have checked the Automatically align the side view checkbox in the screw definition, the screw is rotated to align with the nearest object. If not, you are prompted for a rotation.

15. In the example below, a point is indicated at a 45 degree angle to the screw centre point so that the axes are drawn at a 45 degree angle.
