The sketch at the right may be used to create a part by selecting specific shapes then “cleaning up” the outline by trimming inner curves. The final shape must be a single series of connected lines and arcs. Concept Sketch. (Cannot be used to create a part in this form). Copyrighted Material Profile must be a closed figure with no internal lines. Resulting 3D object with depth added. Copyrighted Material Additional sketches were used to define the protrusion at the middle and the holes in the part after the initial shape was created. Copyrighted Material 26 Solid Edge V16 2D Drawing Copyrighted Material Assembly Sketches (Layouts) These are used to define the critical geometry in a series of mating parts. Elements from the master sketch may be selected to create the individual parts. This assures that the parts are the correct size and are located in exactly the right place. Elements of the part sketches which are derived from the master sketch may be associated (linked) back to the master sketch. This means that any change in the master sketch will update all the associated parts. Copyrighted Material Portions of the sketch were used to create the base of the roller assembly. Other portions of the same sketch will be used to create the opening for the wheel. Copyrighted Material Modeling the wheel is done by selecting the large circle from the master sketch. The final assembly is shown with the parts modeled exactly as they fit. As you can see, 2D sketches are the basis for much of the design and part creation process. These sketches can be very general at first then, exact sizes can be assigned later. All parts associated to the master sketches will re-size to the new dimensions. Copyrighted Material 27 2D Drawing Solid Edge V16 Copyrighted Material Starting a 2D Sketch In this chapter all drawings will start from the Part Environment. Most of the commands and construction techniques are the same in other environments. If Solid Edge is already running, pop down the File menu .... Pick New … Select the More tab Use Normeng.par (inch) Copyrighted Material For an introduction to 2D sketches, we will use the option to create a sketch. This option allows the designer to create an overall master outline showing major features of the part. When the actual part creation takes place, elements from the master sketch will be copied to the part outline sketch. Copyrighted Material Watch the Status Bar for instructions and prompts. · Pick the Front reference plane.

Major lines might be 1 inch while minor lines might be: 8 lines/inch = 1/8 inch (.125) 10 lines/inch = .10 inch, etc. Snap To Grid locks the drawing geometry to the grid. This creates accurate geometry quickly without keying in distances as long as the points can be set to the grid locations. Show Readouts turns on the X - Y display showing the cursor distance from the current Origin. Copyrighted Material Show Alignments projects a dashed line when the cursor is in line with existing geometry. Grid as Points. The grid may be displayed as points if prefered. Cursor Position Display. X and Y pointer locations are displayed as points are set. The distance is from the Origin.

Click a start point and move the mouse. The length of the line and the angle will display. · You can type in a length and an angle in the dialog boxes. · While drawing a line you can switch to the arc command and back. Line to Arc Switch between line/arc Copyrighted Material Clicking the arc button on the ribbon bar switches to the arc command. · An Intent Zone icon is displayed on the end of the line. Moving the mouse through the 4 sectors produces a different result for each sector. Copyrighted Material Point - Available from the fly out menu. Click to place or input coordinates.

Center 3 Points Tangent Ellipse Ellipse Radius/ 3 Points Center Diameter 2 Points Copyrighted Material The ribbon bar accepts either diameter or radius. Tangent can be: · Tangent to one entity · Tangent to two entities including the reference planes. You can set the radius then move the circle tangent. Copyrighted Material Many options exist. Try different commands and ways of using the commands. Online Help gives excellent instructions for the use of each option. 33 2D Drawing Rectangle Solid Edge V16 Copyrighted Material Three construction methods are available: · Use dialog boxes. Input Width, Height and Angle. · Click two points for the width and one point for the height. · Draw a diagonal sketch line with the mouse. Copyrighted Material Sketch Diagonal Line Rectangle Constructed Sketch Editing Tools Select Tool Fillet/Chamfer Used to select entities for editing. Hold down the CTRL Key to select multiple entities. To delete an entity, select it and press the Delete Key Copyrighted Material Fillet will round a corner or add an arc between two entities. Often, Fillet is the easiest way to create an arc when the start/end/center points are not well defined. Chamfer will bevel a corner. The bevel can be the same angle or distance on both sides or, the bevel may be a different distance or angle on each side. Note the expanded ribbon bar. Copyrighted Material B Small rounds, fillets and chamfers should usually be added to the solid model after the major shape has been created. A 34 Solid Edge V16 2D Drawing Copyrighted Material Trim/Extend/Break Trim line Trim Trim Extend Break Corner Trim is used to remove segments of entities. The segments are defined by intersections on the sketch. Copyrighted Material Multiple segments may be trimmed by sketching a line through each entity. Extend will cause entities to intersect. Extend will not work if one entity does not provide a stop for the entity being extended. · You can extend a line by selecting the line and keying in a new length in the dialog box. Copyrighted Material Break will slice an entity into two parts. Construction Lines Any entity may be designated as a construction element. This means that it is used to define geometry but is not considered as a part of the outline shape. Copyrighted Material Construction lines were used to locate the center for the circle. The Construction toggle is on the flyout with the Include command. 35 2D Drawing Solid Edge V16 Copyrighted Material Move/Rotate/Mirror/Scale/Stretch/Delete Move Rotate Mirror Scale Stretch Delete Move. · First click the Select Tool. · Pick the object to move.

Copyrighted Material 37 2D Drawing IntelliSketch Solid Edge V16 Copyrighted Material QuickPick You may have noticed a number of symbols on the lines of the previous examples. These are geometric indicators which constrain the geometry. As you draw these symbols appear. The check box turns the momentary indicators on/off. Copyrighted Material QuickPick is a tool used to sort out the correct item when several possibilities exist due to stacked geometry. Park the mouse for a few seconds and dots will appear. Right-click for the selection list. Copyrighted Material Geometric Relationships As you draw some of the Connect Concentric Tangent relationships are automatically set. Sketches must have the proper relationships between entities in order to create actual parts. Sketches must be properly constrained to create the Horizontal/Vertical Co-Linear Parallel Perpendicular intended objects. Copyrighted Material · Remove a relationship by deleting the marker. · Add a relationship by selecting from the Relationships menu. This menu is near the bottom of the Draw Toolbar.
