logues as shown

8 Drill and tap 3 holes M4

Set the current coordinate system onto the face of the 50mm cylinder

Select the normal (or top) view

Draw a 38mm diameter circle at 0,0

Create another coordinate system at the intersection between the circle and the horizontal axis with (use the cursor slide again if you wish)

Select the drilling icon

Select COORDINATE SYSTEM then click

on the new coordinate system, then the

cylinder face Choose the tapped hole and

fill out the dialogue as below (note the

depth of the holes)

Propagate the holes with a circular propa-

gation using the 50mm cylinder as the

propagation axis We need 3 holes

Finally put 1mm fillets around the

edges and corners of the feet as shown

9 Detail drawing of the body

Open a new document with select Draft as the document type

Create a main view and projected view as shown

10 Section view

Click on the section icon then onto the main view

Click the circle; the circles axis will appear automatically, use the vertical line of the axis as the cutting contour

Select OK

Set the hidden lines to HIDDEN then OK

Place the view on the drawing

11 Partial section

Draw the projected axis

Draw a line from the centre of the 50mm hole to the centre of the drilled hole in the foot

You can use the trim function to extend as well as shorten Select the line and click on a point just outside the foot (as shown)

Select MAKE TRIM

Click on the partial section icon

Select the view

Click on the line we have just drawn

Select OK

Set hidden lines as HIDDEN, then OK

You will see that the view is incorrectly aligned, go back and select NO and YES as shown

Position the view correctly and Esc to exit the com-

mand

Dimension the rest of the drawing as shown

Piston

Topics covered:

• Freehand contour

• Revolved solid

• Grooves

• Slots

• Drilling on cylinders

1 Shape creation

Open a new document select Design as the type.

Draw the initial profile as shown

Dimension with

Revolve the shape with

2 Groove

Select the groove icon

Click on the face as shown

Click on the front face

Select OK

Enter the values d=5, D=45 and l=2

Then OK

3 The Slot

Place a coordinate system on the back face From the coordinate sys-

tem menu bar, select Constrained coordinate system on face

Draw the axis on the circular outline

Select the slot icon

Select the face

Click on the vertical axis line

Choose the U type slot Then OK

Type 4mm OK

Type 10mm OK

Select OK.

4 Drill the Ø4 hole

As the face to drill through is not planar we will need to use a coordinate

system

Select the current coordinate system icon

Select ABSOLUTE COORDINATE SYSTEM

Select the top view icon

From the points menu bar , draw a point

Place the point 5mm in from the end of the 15mm diameter

Create a coordinate system on a face and point face = face of the Ø15 cylinder and the point is the preceding point

Drill the hole using this coordinate system Make it a plain drilled hole Ø4 through all

Arm

Topics covered:

• Sketch Contours

• Modifying elements

• Extrude solids

• Unite

• Merge (contours)

• Pocket

• Drilling

• Standard profiles

• Fillets

• Some advanced drawing methods

1 Arm profile

Open a new document select Design as the document type

Draw 2 circles with the circle icon and dimension change to a dotted

line first

NOTE: You can draw the circles roughly then correct their size and position using the

dimension tool, however it’s a good idea to place the first one on the coordinate 0,0

Draw a 2 lines tangent to the 2 circles use the Contour command but use a different colour

Click the first circle

Ensure PASS ON SEGMENT is selected, click the second circle at 2 o’clock and again at 5 o’clock

Click on the first circle to close the profile

2 Modify an element

Click on the modify tool then select the top straight-line segment of your profile

Simply type 125mm as the circle size (no need to select the circle button) and Enter

If the arc goes the wrong way, click on the tool again and select INVERT

Repeat the procedure for the bottom arc using 70mm radius

3 Extrude the shape

Use the extrude icon extrude the 2 circles to a thickness of 11mm (CENTRED)

NOTE: Use the lasso to select them both at the same time

Then extrude the contour by 5mm (CENTRED)

Unite

Select the centre shape

Select the two cylinders

Esc to exit

4 Merge contours

Draw a circle Ø14 and a rectangle

3X5 as shown : use the

RECTANGULAR option and select the two

diagonal points

Hold down the right mouse key and select

AUTO DIMENSION, then use SYMMETRY

constraints to add a constraint on the X axis

Add a 10mm dimension to position the rectan-

gle

Use the merge icon to merge the 2

contours together Remember to pick the contours

on the section you wish to keep

5 Pocket

With the pocket command use the profile to cut the pocket on the boss

Select the face

Select the profile

Select Through all and OK

6 Drilling

With the drilling icon click on the face of the other

boss As the boss is circular the system will automatically

select the centre Select a plain hole then OK

Type in 10mm for the diameter and click Through all then

OK

7 Do the drawing

Use the New document icon then select Draft as the document type and select a Associative

A4 horizontal mm template Your windows will tile vertically automatically

Select the main view icon

Select AUXILIARY VIEW (or right click) to create the projected and isometric views as shown

8 Create a detail view

Click on the detail view icon

Click on the main view (shown above with a highlighted border)

Place the view where you want it.

9 Projected dimensions

Activate the dimensions context menu then select the projected dimensions icon

Select the main view

Click on AUTOMATIC

Repeat for the other views

Select CIRCLE

10 Modify the Arm

Open the fie Arm.top

To see the elements that are driving the model

click on the driving elements icon

Click on the centre face

Use the circle tool to draw an arc of radius 90mm passing through the centre of the 2 circles

NOTE: change the color and line style using and

11 Standard Profile

Draw a radiused slot using a standard profile

Double click on each of the values Type in 90mm for the radius, 10mm for the thickness and 20 degrees for the angle Ensure the key point is set to middle
