SolidWork 2013 - Drawing Different Type Of Ellipes

DRAWING ELLIPSES

CommandManager: Sketch > Ellipse

SolidWorks menus: Tools > Sketch Entities > Ellipse

Toolbar: Sketch > Ellipse

In SolidWorks, an ellipse is drawn by specifying its centerpoint and two ellipse axes by moving the mouse. To draw an ellipse, choose the Ellipse button from the Sketch CommandManagert. Move the cursor to the point that you want to specify as the centerpoint of the ellipse. Press the left mouse button at that point and then move the cursor to specify one of the ellipse axes. You will notice that a reference circle is drawn and two values are displayed above the ellipse cursor. The first value that shows R = * is the radius of the fi rst axis or the major axis that you are defining and the second value that shows r = * is the radius of the other axis or minor axis of the ellipse. While defining the first axis, the second axis is taken equal to the first axis. That is why a reference circle is drawn and not a reference ellipse. Specify a point on the screen to define the first axis. Next, move the cursor to size the other ellipse axis. As you move the cursor, the second value above the ellipse cursor that shows r = * and the value in the Radius 2 spinner in the Ellipse PropertyManager will change dynamically. Specify a point in the drawing area to define the second axis of the ellipse.

DRAWING ELLIPTICAL ARCS

CommandManager: Sketch > Ellipse fl yout > Partial Ellipse

SolidWorks menus: Tools > Sketch Entities > Partial Ellipse

Toolbar: Sketch > Ellipse fl yout > Partial Ellipse

In SolidWorks, the process of drawing an elliptical arc is similar to that of drawing an ellipse. You will follow the same process of defining the ellipse first. The point that you specify on the screen to define the second axis of the ellipse is taken as the start point of the elliptical arc. You can define the endpoint of the elliptical arc by specifying a point on the screen. After drawing the elliptical arc, you can also modify its parameters in the Ellipse PropertyManager

DRAWING PARABOLIC CURVES

CommandManager: Sketch > Ellipse fl yout > Parabola

SolidWorks menus: Tools > Sketch Entities > Parabola

Toolbar: Sketch > Ellipse fl yout > Parabola

In SolidWorks, you can draw a parabolic curve by specifying the focus point, apex point, and then two endpoints of the parabolic curve.

To draw a parabolic curve, choose the Parabola button from the Ellipse flyout; the cursor will be replaced by the parabola cursor. Move the cursor to the point that you want to specify as the focal point of the parabola. Press the left mouse button once at that point. You will notice that a reference parabolic arc is displayed. Then, move the cursor to define the apex point and to size the parabola. As you move the cursor away from the focal point, the parabola will be flattened. After getting the basic shape of the parabolic curve, specify a point by using the left mouse button. This point is taken as the apex of the parabolic curve. Next, specify two points with respect to the reference parabola to define the guide of the parabolic curve. As you move the mouse after specifying the focal point of the parabola, the Parabola PropertyManager will be displayed with the options inactive. These options will be available only after you have drawn the parabola.

DRAWING CONIC CURVES

SolidWorks menus: Tools > Sketch Entities > Conic

In SolidWorks, you can draw a conic curve by specifying the endpoints and the Rho value.

To create the conic curve, choose Tools > Sketch Entities > Conic from the Solidworks menus. Click to specify the first end point of the conic curve and move the cursor away from it; a reference line will get attached to the cursor. Next, click to specify the second endpoint of the conic curve and move the cursor away from it; the preview of the conic curve will get attached to the cursor and will be displayed in yellow color and the Conic PropertyManager will be displayed with its options inactive. As you move the cursor, the curve will change dynamically with the cursor movement. Move the cursor to a distance and click to specify the top vertex of the conic curve to be drawn. A reference line will be generated and the Rho value will be displayed above the cursor. As you move the cursor, the Rho value of the conic curve will be modified accordingly. Click the left mouse button when the required Rho value is displayed above the conic cursor; the conic curve will be created and the options of the Conic PropertyManager will be activated. You can also modify the parameters of the conic curve drawn by using this PropertyManager.
