The Sketching EnvironmentA solid model is a combination of sketched features, placed features, and derived

features. The base feature of any design is a sketched feature and is created by

invoking theSketchbutton and then drawing the sketch in the sketching environment.The sketching environment of SolidWorks can be invoked any time in the Partmode,

Assemblymode, and Drawingmode.

Learning About Sketcher TermsSome terms that are used in the sketching environment are:

Origin

The origin is a red color icon (displaying the X and the Y axis direction) is displayed

in the middle of the sketching environment screen. The point of intersection of these

two axes is the origin point and the coordinates of this point are 0,0.

Inferencing LinesThe inferencing lines are the temporary lines that are

used to track a particular point on the screen. The

inferencing lines that are displayed on the screen will

be either blue or brown in color.

Using inferencing lines to locate the

center of an arc


10/48

Select Tool

The Selecttool is used to select a sketched entity or exit any sketching toolthat is active. Remember that only those entities will be selected that lie

completely inside the window that you have defined using Selecttool.


11/48

Drawing Lines

The lines are one of the basic sketching tools available. To draw a line in thesketcher environment of SolidWorks, choose the Linetool. You will notice that

the cursor that was an arrow earlier is replaced by the line cursor. The methods

to draw lines are:

Drawing Continuous Lines

This is the default method of drawing lines. In this method you just have to

specify the startpoint and the endpoint of the line using the left mouse button. The line attached with the endpoint of first line even you are finished with

drawing the first line, is called a rubber-band line. The reason it is called a

rubber-band line is that this line will stretch like a rubber-band as you move

the cursor. To exit the continuous line drawing process press the ESC key

from the keyboard, or choose the Selecttool, or double-click on the screen,

or right-click to display the shortcut menu and choose the End Chainoption

from the shortcut menu.


12/48

Drawing Individual Lines

This method is to draw individual lines. Thestartpoint of the next line will not necessarily

be the endpoint of the last line. To draw

individual lines, press and hold down the

left mouse button and drag the cursor from

the startpoint of the line to the endpoint.

Once the cursor is dragged to the endpoint,

release the left mouse button. To make theprocess of sketching easy, you are provided

with the PropertyManager. ThePropertyManager is a table that is

displayed on the left of the screen as soon

as you select the first point of any sketch

entity, see Figure A.Figure A Partial display ofPropertyManager


13/48

When drawing lines in the sketcher environment, a numeric value is displayed

above the line cursor, see Figure B. This numeric value indicates the length of

the line that is drawn. This value is the same as that in the Lengthspinner of theLine PropertyManager. The only difference is that in the Line

PropertyManager, the value will be displayed with more precision.

Figure B The length of the line displayed on thescreen while drawing the line


14/48

SolidWorks automatically applies the Horizontal (H symbol) and Vertical(V symbol) relations to the lines drawn in respective horizontal and vertical

directions. These relations ensure that the lines that you draw are vertical orhorizontal and not inclined, see Figure Cand D.

Figure C Symbol of the

Horizontalrelation Figure D Symbol of the Verticalrelation


15/48

Drawing Construction Lines

Construction lines are the ones that are drawn only for the aid ofsketching. These lines are not considered while converting the sketches

into features. When you draw a construction line, using Centerlinetool,

the For Construction check box in the Line PropertyManager is

selected.


16/48

Drawing CirclesChoose the Circlebutton to draw the circle. The

arrow cursor is replaced by the circle cursor, see

Figure A. Specify the centerpoint of the circle

using the left mouse button. Move the mouse on

the screen to define any arbitrary radius of the

circle. To modify the circle radius value to thedesired value use theCircle PropertyManager,see Figure B.

Figure B CirclePropertyManager

Figure A Sketching a circle


17/48

Sketching a Construction Circle

To sketch a construction circle, draw the circle using the Circletool and then

select the For Construction check box available in the Circle

PropertyManager.


18/48

Drawing ArcsYou can draw the arcs using three methods: Tangent Arc, Centerpoint Arc, and 3

Point Arc. All these methods can be invoked separately by choosing their respective

buttons from the Sketch Toolstoolbar.

Drawing Tangent Arcs

The tangent arcs are the ones that are

drawn tangent to an existing sketched

entity. Invoke the Tangent Arc tool andthen move the arc cursor close to the

endpoint of the entity that you want to

select as the tangent entity. Notice that the

arrow cursor is replaced by the arc cursor.

An arc cursor consists of a pencil and an

arc below the pencil, see Figure A. Figure A Sketching atangent arc


19/48

When you complete a tangent sketch by

specifying its endpoint, the SolidWorks

information box is displayed as shown in

Figure B. This dialog box will informyou to select the endpoint of a sketched

entity to draw another tangent arc.

Figure B SolidWorksinformation box

You can draw an arbitrary tangent arc

and then modify its value using the ArcPropertyManager, see Figure C.

Figure C Arc PropertyManager


20/48

Drawing Centerpoint Arcs

The centerpoint arcs are the ones that are drawn by defining the

centerpoint, startpoint, and endpoint of the arc. Invoke the CenterpointArc tool, the arrow cursor is replaced by the arc cursor. Press the leftmouse button once at the location of the centerpoint. The size of the

dotted circle will modify with the movement of the mouse as you

approach to the startpoint of the arc, see Figure A. Press the left

mouse button once at the startpoint of the arc. Move the cursor in the

clockwise or counterclockwise direction, the resultant arc will be drawn

in the respective direction. Specify the endpoint of the arc using the left

mouse button, see Figure B.

21/48

Drawing 3 Point Arcs

The 3 point arcs are the ones that are drawn by defining the startpoint

and endpoint of the arc, and a point somewhere on the arc. Invoke the3 Pt Arctool, the arrow cursor is replaced by the arc cursor. Move the

arc cursor to the point to specify the startpoint of the arc, see Figure A.

To specify the direction of the arc specify a point on screen using the

left mouse button, see Figure B.

22/48

Invoking the Options to Draw an Arc from within the Line Tool

The option to draw an arc using Linetool can be

invoked only if at least one sketched line, arc, orspline exists on the screen. To draw an arc

tangent to the last line drawn using the current

Line tool sequence, move the cursor in the

direction in which the arc should be drawn from

the endpoint of the line and then move it back

close to the endpoint, see Figure A. The line

cursor is replaced by the arc cursor and the Line

PropertyManager is replaced by the Arc

PropertyManager. To draw a normal arc, move

the cursor away from the endpoint and then

move it back close to the endpoint. Move the

cursor normal to the existing line and then move

the cursor in the direction in which the arcshould be drawn, see Figure B.

Figure A Drawing the tangent arc

Figure B Drawing the normal

arc


23/48

Drawing RectanglesA rectangle can be drawn by specifying two opposite corners of the rectangle.

Invoke theRectangletool. The arrow cursor will be replaced by the rectangle

cursor. Move the cursor to specify the first corner point of the rectangle. Press

the left mouse button once. Move the cursor and specify the other corner of

the rectangle using the left mouse button. The length and width of the

rectangle are displayed above the rectangle cursor. The length is measured

along the X axis and the width is measured along the Y axis, see Figure A.

Figure A Drawing a rectangle by

specifying two opposite corners


24/48

Drawing ParallelogramThe Parallelogramtool Tools > Sketch Entity > Parallelogramcan be used to draw

a parallelogram and also to draw a rectangle at an angle. The methods to draw both

these entities are:

Drawing a Rectangle at an Angle

Invoke the Parallelogram tool. Move the parallelogram cursor to

the startpoint of one of the edges of the rectangle. Press the left

mouse button once. Move the cursor to size the edge. Based onthe current position of the cursor, a reference line will be drawn

either horizontal, vertical, or aligned. Specify the endpoint of the

edge. The resultant reference line is at an angle. Move the cursor

to specify the width of the rectangle. A reference rectangle is drawn

at an angle. The width will be specified normal to the first edge.

Using the left mouse button, specify a point on the screen to define

the width of the rectangle. The reference rectangle will be

converted into a sketched rectangle, see Figure A.

Figure A Rectangle

25/48

Figure A Parallelogram drawn at

an angle

Drawing Parallelogram

The process of drawing a parallelogram is similar to

that of drawing a rectangle at an angle. Invoke theParallelogram tool from the menu bar. The cursor

will be replaced by the parallelogram cursor.

Specify two points on the screen to define one edge

of the parallelogram. Next, press the CTRL key

from the keyboard once and then move the mouse

to define the width of the parallelogram. The width

is no more added normal to the first edge. A

reference parallelogram will be drawn with the

movement of mouse. Specify the point on the

screen to define the size and shape of the

parallelogram. Figure A shows a parallelogram

drawn at an angle.


26/48

Drawing PolygonsA polygon is defined as a multisided geometric figure

in which the length of all the sides and the angle

between all the sides are the same. In SolidWorks, a

polygon with the number of sides ranging from 3 to 40

can be drawn. The dimensions of a polygon are

controlled using the diameter of a construction circle

that is either inscribed inside the polygon or

circumscribed about the polygon. Invoke the Polygontool. The arrow cursor will be replaced by the polygon

cursor. Using the left mouse button, specify a point on

the screen after reaching the desired length and

rotation angle of the polygon. To modify the

parameters such as the centerpoint of the polygon,

the diameter of the construction circle, the angle of

rotation of the polygon, and so on use the PolygonPropertyManager, see Figure A.

with the construction circle inscribed

inside the polygon.

Figure Cshows a five-sided polygon with

the construction circle circumscribed

outside the polygon.

Notice that the reference circle is retained with the polygon. Remember that thiscircle will not be considered while converting the polygon into a feature.


28/48

Drawing SplinesInvoke the Spline tool to draw a spline. The

splines can be drawn using two methods. In

the first method, which is the default method,

you can draw a spline by continuously

specifying the endpoints of the spline

segments using the left mouse button. In the

second method of drawing a spline, you have

to specify the first point of the spline and thenpress and hold the left mouse button and drag

the cursor to define the second point of the

spline, thus creating a segment of the spline.

The number of points specified in a spline are

taken as the handles or control points of the

spline. These handles are used to modify the

shape of the spline. Figure Ashows a splinewith startpoint as origin.

Figure A A spline with

startpoint as origin


29/48

Drawing PointsTo draw a point, choose the Point tool and then specify the point on the

screen to place the point. The Point PropertyManagerwill be displayed with

the X and Y coordinates of the current point. Point PropertyManagercan be

used to modify the location of the point by modifying its X and Y coordinates in

the.


30/48

Drawing EllipsesInvoke the Ellipsetool Tools > Sketch Entity > Ellipse from the

menu bar. The arrow cursor will be replaced by the ellipse cursor.

Press the left mouse button once to define the centerpoint. Then

move the cursor to specify one of the ellipse axis. A reference

circle is drawn and two values are displayed above the ellipse

cursor, see Figure A. Using the left mouse button, specify a point

on the screen to define the second axis of the ellipse, see Figure

B. Figure Cshows partial view of Ellipse PropertyManager.

Drawing Elliptical ArcsInvoke the Tools > Sketch Entity > Centerpoint Ellipsetool

from the menu bar. The process of drawing an elliptical arc is

similar to that of drawing an ellipse. Follow the same process

of defining the ellipse first. The point that is specified on the

screen to define the other axis of the ellipse is taken as the

startpoint of the elliptical arc. To define the endpoint of the

elliptical arc specify a point on the screen, see Figure A.

Figure Bshows the Ellipse PropertyManager.

32/48

Drawing A Parabolic CurveInvoke the Tools > Sketch Entity > Parabola tool

from the menu bar. The cursor will be replaced by the

parabola cursor. Specify the focal point of the parabola

and then specify two points (one the apex and the

other the size) on the guide lines of the parabolic

curve. You will notice that a reference parabolic arc is

displayed, see Figure A. Figure B shows the

Parabola PropertyManager.
