Screws

Screws are the most common elements used to connect components. In addition to connecting, screws are also used for setting, measuring or tensioning. Screws and their threads are largely standardised. They are used both as individual parts and in combination with nuts and washers as screwings. The most common screw types used in mechanical engineering can be called up directly with ELITECAD using their DIN standard and then inserted into the construction.

Create screws

	Standard parts toolbar
	ME-Objects menu > Standard parts > Screws

With a click on the function TOOLS > STANDARD PARTS > CREATE SCREW in the toolbar or by selecting ME-OBJECTS > STANDARD PARTS > SCREW in the menu bar, the settings of the last screw drawn are active in the parameter window and the standard part can be set immediately.

Screws property bar

The property bar is visible as soon as an existing screw is selected for editing. Clicking on the screw activates the property bar and the main values of the depiction of the screw can be manipulated. Using the icon , the associated parameter window opens and all available values of the screw can be modified.

Depiction (see General parameters)

Screw parameters

Decide whether the screw should be created in 2D or in 3D.

Tip

Specify the thread diameter value first and then the screw length. The selection window will only offer dimensions that are available according to the selected standard.

The completed dialog is confirmed with . This means that the screw is dynamically active at the cursor for positioning in the drawing. The reference point is the intersection of the head contact surface with the screw centre line.
The function is ended when it is positioned within the construction.
The function can be opened repeatedly for other screws of the same type. The last input parameters are retained and are suggested the next time it is opened.
