Introduction Creating Geometry Pull

Click the Pull icon to exit the sketch. Clicking another tool will immediately exit you from the current tool.

Look on the Mode Menu Space Claim automatically change from sketch mode to 3D mode.

Select on the surface by clicking on it. Once a surface is selected it can be pulled to create a solid from anywhere on screen (you do not need to click on the small yellow arrow).

Hold the left mouse button and drag the surface upward. Use the Spacebar to freeze the dimension and type .5 to make the solid half an inch thick.

2012 ANSYS, Inc. June 4, 2014 11

Introduction Creating Geometry Sketch on Face

After creating the solid, click the top surface and then choose the Circle icon in the Sketch group. Again Space Claim automatically switch to the correct mode.

To bring the selected surface parallel to the screen, select the Plan View button from the Orient group towards the left of the ribbon bar.

2012 ANSYS, Inc. June 4, 2014 12

Introduction Creating Geometry Sketching Circles

Click on the axis of one of the full rounds (a small green circle will appear to indicate concentric alignment) and sketch a circle with a diameter of .75in.

Repeat this process on the other end of the model. Notice that the second circle will snap the same size of the circle youve already created.

2012 ANSYS, Inc. June 4, 2014 13

Introduction Creating Geometry Shift-Touch Dimensions

To dimension a sketch entity from another object click the shift button while hovering over an edge, midpoint or vertex. Hover over the middle of the lower line until a green triangle appears (indicating the midpoint). Press the Shift key and dimension 1 inch directly upwards to start the circle as shown.

2012 ANSYS, Inc. June 4, 2014 14

Introduction Creating Geometry Concentric Circles

Click once to start the circle at the centre of the plane and make the circle with the diameter of 1.5 inches.

Make another coaxial circle with a diameter of 1-inch.

2012 ANSYS, Inc. June 4, 2014 15

Introduction Creating Geometry Exit Sketch

2012 ANSYS, Inc. June 4, 2014 24

Introduction Creating Geometry Pull Up To

Select the new surface youve created and go to the toolguides on the right of the screen.

Click the bottom toolguide which is Up To. This allows us to snap a surface or face up to another. After the Tool guide is selected select the outer cylindrical face behind the surface.

2012 ANSYS, Inc. June 4, 2014 25

To enter a dimension, hit Spacebar and type in .2. Repeat this on the other hole.

Introduction Creating Geometry Fillet Rounds

Click the edge of one of the holes. Notice that it will highlight in bright green. While holding the left mouse button, drag your mouse to place a round on the hole.

2012 ANSYS, Inc. June 4, 2014 26

Introduction Creating Geometry Fillet a Chain of Rounds

Double click one of the outer edges to grab the loop of edges as shown. Place a round of .1 on the model.

2012 ANSYS, Inc. June 4, 2014 27

Introduction Creating Geometry Apply Full Round

Hold down Ctrl and select on the three surfaces highlighted at right. RMB and select Full Round from the pop-up menu to create a full round based on the three surfaces. You must be in pull mode for this option to be visible.

Note: The context-sensitive RMB menu allows common tasks to be completed with little cursor movement.

2012 ANSYS, Inc. June 4, 2014 28

Introduction Creating Geometry Save Part

Save the part as Base.scdoc in the IntroTraining folder.

2012 ANSYS, Inc. June 4, 2014 29

Introduction Creating a simple Assembly

Goals: - use advanced sketch and 3D tools

- become familiar with assembly

Guiding thread case: - start from scratch to a simple assembly

2012 ANSYS, Inc. June 4, 2014 31

Introduction Creating a simple Assembly Options

To begin we will change some options. Go to the File menu in the top left corner of the screen. Once there select SpaceClaim options

at the bottom

Then go to the advanced tab and make sure that Auto-extrude is on. These will allow you to create solids in section mode and power select quicker.

Go to the units tab and make sure you are in Metric.

2012 ANSYS, Inc. June 4, 2014 32

Introduction Creating a simple Assembly Orient Sketch Grid

You will begin all SpaceClaim by sketching on the top plane. To sketch on the front click the select new sketch plane button and then click in the upper right hand corner of the screen.

2012 ANSYS, Inc. June 4, 2014 33

Introduction Creating a simple Assembly

Plan View and Shortcuts

To view a heads up display click the Plan View button. (This is located in the bottom right hand corner of your sketch grid, or located in the upper left region of the ribbon tool bar)

Please note that the keys shortcut for this operation is V. Shortcuts will be given in all of the tooltips.

2012 ANSYS, Inc. June 4, 2014 34

Introduction Creating a simple Assembly Cylinder

The first thing we will sketch will be a cylinder. Select Cylinder in the Shapes group in the Insert menu.

Click once to start the cylinder. Make the cylinder vertical and type in a value of 400 for the height.

It will then look for a value for the diameter. Enter in a value of 280.

2012 ANSYS, Inc. June 4, 2014 35

Introduction Creating a simple Assembly Spin, Pan, and Zoom

Youve just created a solid and we can see it in the structure tree on the far left of the screen.

To view it easier we can spin, pan, or zoom around our model. To spin, hold down the Middle Mouse Button (MMB). To pan, hold Ctrl+MMB. To zoom, hold Shift+MMB.

2012 ANSYS, Inc. June 4, 2014 36

Introduction Creating a simple Assembly Display Tab

To change the graphics or display of your design, go to the Display Tab. Here you can turn Fade Scene Under Grid off, and turn Clip Scene Above Grid on. You can play with these options to get the graphics you prefer.

2012 ANSYS, Inc. June 4, 2014 37

Introduction Creating a simple Assembly Orient View

Go Back to the Design Tab and click Plan View (V).

2012 ANSYS, Inc. June 4, 2014 38

Introduction Creating a simple Assembly Cylinder

1-Now we will make another cylinder.

2-Start at the midpoint shown with the triangle in the picture on the left.

3-Create a cylinder 1200 mm tall and with a diameter of 100 mm.

2012 ANSYS, Inc. June 4, 2014 39

Create a rectangle 700 mm by 100 mm.

After sketching the rectangle click Section Mode (X) located in the middle of the ribbon bar. Notice that the sketch turned into a surface. Now we will be able to start sketching solids.

Introduction Creating a simple Assembly Sketch vs. Section Mode

Now go to the rectangle sketch tool.

Start the sketch on the midpoint of the axis.

2012 ANSYS, Inc. June 4, 2014 40

Introduction Creating a simple Assembly 3D Direct Sketching

Create another rectangle to make a keep out for a chair. Notice that you now have three dimensions. The dimension of 10 is the depth. This depth will extrude both ways from the sketch. Change it to 100.

You can change the value if you like, but once you click a second time to complete the rectangle you will get a solid as seen in the structure tree below.

2012 ANSYS, Inc. June 4, 2014 41

Introduction Creating a simple Assembly Orient View

Rotate the view to see the solid youve created.

Click Plan View (V) after looking at it to go back into a heads up view.

2012 ANSYS, Inc. June 4, 2014 42

Introduction Creating a simple Assembly 3D Direct Sketching

Create another rectangle for a tray. We are still ball parking the design so simply make a thin rectangle starting within the last rectangle and snap it to the edge of the cylinder. Make the depth of this solid 600 mm.

Notice that we should now have three solids and one surface in the structure tree.

2012 ANSYS, Inc. June 4, 2014 43

Introduction Creating a simple Assembly Section Edits

Select the Split Face tool and click on the rightmost edge of the large chair rectangle.

Select Pull (P). Select the large green line indicated in the middle picture and pull it back to form an L.

Note: In section mode the cross- hatching is not selectable.

2012 ANSYS, Inc. June 4, 2014 44

Introduction Creating a simple Assembly Cylinder

Select the Cylinder tool in the upper right of the Ribbon bar.

Sketch a cylinder connecting the chair to roughly the middle of the surface indicated below.

2012 ANSYS, Inc. June 4, 2014 45

Introduction Creating a simple Assembly Cylinder

Create a second cylinder at an angle from the first one.

2012 ANSYS, Inc. June 4, 2014 46

Introduction Creating a simple Assembly Sphere

Select the Sphere tool.

Starting from the intersection of the two cylinders, make the sphere big enough to encompass the entire intersection.

2012 ANSYS, Inc. June 4, 2014 47

Introduction Creating a simple Assembly Sketching Completed

Look at the structure tree. You should have four solids and one surface: a Chair, Tray, Stand, and Arm.

2012 ANSYS, Inc. June 4, 2014 48

Introduction Creating a simple Assembly 3D Mode
