Drawing Lines

To design parts with eMachineShop you draw straight lines, rectangles, circles, arcs, splines, and text. 

straight.gif (136 bytes) To draw a straight line: click this button; click in the workspace at the starting point; click again at the end point. To restrict the angle of the line to be exactly horizontal or vertical or a multiple of the Rotation Snap Angle , hold down the CTRL key while drawing.

To draw a rectangle: click this button; click in the workspace at one corner; click again at the other corner.

To draw a circle: click this button; click in the workspace at the center; click again at the desired radius.

To draw an arc: enable the arc button with Edit | Preferences | Customize | Arc button. Click the Arc button; click in the workspace at the center; click again at the clockwise end of the desired arc; click again at the counter-clockwise end of the arc. Instead of drawing an arc, it is often easier to draw a circle crossing other lines and then apply the Intersect command. (The Arc button is not enabled by default as it is generally more convenient to use Line | Corner | Round or to create a circle and use the Intersect feature.)

A spline is a curve that can be used to create a wide variety of shapes that cannot easily be made with arcs. For example, you might use a spline to create sections of the outer shape of a violin. To draw a spline: click this button; in the workspace click to specify the start point; move to the desired end point and click; then drag the two external handles to adjust the shape.
