Step 4.3: Level 1: Add Profile and Extrusions to a Part

Add Profile and Add Hole

Add-Profile : add a Profile to a sketch-loop

Add-Hole : add a Hole to a sketch-loop to cut through a Profile.

Profile and Extrusion elements

•A Profile is two offset contours that are copies of a sketch-loop

•The Extrusion is automatically added to the model with the Profile.

•The Extrusion fills the gap between the Profile contours

The Extrusion has parameters that you can edit with the Extrusions dialog:

•Parameters: Color, Transparency, Density.

•Distances: Part Offset, Extrusion Offset, Extrusion Depth

Note: The Profile/Extrusion is a Solid we call MD-Solid. The other type is a CAD-Solid, which you import from CAD onto a CAD-Line.

GST-4-3-001

STEP 1: Add a sketch-loop to a Part

Do Tutorial 3
or
File menu > Open the file you have saved from Tutorials 3.
or
Edit a Part to add a new sketch-loop that is similar to the image to the left - from Tutorial 3

GST-4-3-CM-AddProfile-00

STEP 2: Start the Add Profile command

GST-Icon-AddProfile

Click Solids toolbar > Add Profile

or

MD16: Click Add menu > Mechanism sub-menu > Solids sub-menu > Add Profile.

MD17 : MD-Solids menu > Profile

GST-4-3-002

STEP 3: Select a sketch-element

1.Click one sketch-element that is in the sketch-loop

GST-4-3-CM-AddProfile-01

STEP 4: Complete the Command

1.Click OK-tiny-13-17 in the Command-Manager

GST-4-3-003

The Profile contours are (default) PINK

In the Front-View the Profile contours hide the sketch-loop.

Note: You can edit the color of the Profile contours in Application Settings | Graphics tab : Display Colors.

The Profile and Extrusion in the Assembly-Tree

If you expand the Mechanism element in the Assembly-Tree, you see the:

•PartRed-14-1b

•The ProfileRed-14-2 is a child to the Part

•The ExtrusionRed-14-3 is a child to the Profile

 

 

GST-4-3-004

The Profile and Extrusion in the graphics-area

The Profile has two contours - the Primary-ContourRed-14-1b and Secondary-ContourRed-14-2.

The default position of the Primary Contour is coplanar with the sketch-loop, and Mechanism-Plane.

 

 

GST-4-3-005

STEP 5: Open the Extrusion dialog

1.SHIFT+CLICK the Pink Profile  

The Profile and the Extrusion show in the Selection-Window.

2.Right-Click the Extrusion

In the Shortcut menu

3.Click Edit element

The Extrusion dialog is open.

STEP 6: Edit the Extrusion

1.Enter Extrusion Depth = 30

2.Enter Extrusion Offset = 10

Distance to Primary Contour = ( Part Offset + Extrusion Offset ).

GST-4-3-006

GST-4-3-007

 

Show the Extrusion in the Mechanism-Editor use :

•Enable Visibility toolbar > Show Solids in Mechanisms.

 

Hide the Extrusion again:

•Disable Visibility toolbar > Show Solids in Mechanisms.

GST-4-3-008

STEP 1: Edit the Part

1.Double-click the Part-outline of the Part

The Part-Editor is now open

STEP 2: Start the Add Circle command

GST-Icon-SE-Circle

Click Geometry toolbar  > Add Circle

STEP 3: Add two Circles.

Use these two techniques.

TECHNIQUE 1

1.Hover above a PointRed-14-1.

2.Click and Drag the radius of the Circle.

The center-Point merges with PointRed-14-1 when you release your mouse.

GST-Icon-SE-Coincident

TECHNIQUE 2

1.Drag the Circle near to the PointRed-14-2

2.Click Constraints toolbar > Add Coincident (see left)

a.Click the center-Point that is near to the end-Point of the CAD-Line

b.Click the end-Point of the CAD-Line

c.Click the graphics-area.

The center-Point of the Circle and the end-Point of the CAd-line should now be coincident.

GST-4-3-009

STEP 4: Add Dimensions and Constraints

GST-Icon-SE-Equal

1.Click Constraints toolbar > Add Equal Constraint

a.Click the two Circles

GST-Icon-AddDimension

1.Click Geometry toolbar > Add Dimension

a.Click a Circle

The Dimension dialog opens:

3.Right-click the dimension-box

a.Click Round

The Dimension changes to the nearest integer that is exactly divisible by the Spin-Increment value.

b.Edit the Spin-Increment to 1

c.Use the spin-box tool to edit the value to 16

GST-4-3-012

You have fully-defined the Circles:

•the centers are coincident with Points in the Part

•the Radii are equal; one has a dimension

The sketch is Green in the Part-Editor to show it is fully-defined.

4.Close the Part-Editor – Double-click a sketch-element.

We will now add the Holes through the Extrusion.
tog_minusAdd the Holes

GST-4-3-CM-AddHole-1

STEP 1: Do Add Hole

GST-Icon-AddHole

1.Click Solids Toolbar > Add Hole (above the graphics-area)

You must click two elements to do Add Hole.

a)Click the prepared Circle in the Part

b)Click the Profile through which you want to cut the hole

2.Click OK-tiny-13-17 in the Command-Manager

3.Do 1-2 again to add the other Hole.

The Holes have cut through the Profile/Extrusion.
