Add-Profile to add a sketch-loop and an Profile to a Part.
Add-Hole to a sketch-loop to cut a Hole through a Profile.
Before you do Add Hole, you must add the sketch-loop to the Part.
•A Profile is two offset contours – the Primary-Contour and Secondary-Contour
•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.
STEP 1: Add a sketch-loop to a Part
|
|||
STEP 2: Add a Profile
|
|||
2.Click one sketch-element that is in the sketch-loop |
|||
3.Click |
|||
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 in the Assembly-Tree, you see the: •Part •The Profile •The Extrusion
|
|||
The Profile and Extrusion in the Graphic-area The Profile has two contours - the Primary-Contour The default position of the Primary Contour is coplanar with the sketch-loop, and Mechanism-Plane.
|
|||
STEP 2: 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 Contextual menu 3.Click Edit element |
|||
The Extrusion dialog is open. STEP 2: Edit the Extrusion 1.Enter Extrusion Depth = 30 2.Enter Extrusion Offset = 10 Distance to Primary Contour = ( Part Offset + Extrusion Offset ). |
|||
To show the Extrusion in the Mechanism-Editor use : •Visibility toolbar > Show Solids in Mechanisms.
However, hide the Extrusion again •Visibility toolbar > Hide Solids in Mechanisms. |
STEP 1: Edit the Part STEP 2: Click Geometry toolbar > Add Circle |
|
Add two Circles. Use these two techniques. TECHNIQUE 1 1.Hover above a Point 2.Click and Drag the radius of the Circle. The center-Point merges with Point TECHNIQUE 2 1.Drag the Circle near to the Point 2.Click Constraints toolbar > Add Coincident (see left) a.Click the Circle near to the end-Point of the CAD-Line b.Click the end-Point of the CAD-Line |
|
STEP 3: Add Dimensions and Constraints 1.Click Constraints toolbar > Add Equal Constraint a.Click the two Circles 2.Click Geometry toolbar > Add Dimension a.Click a circle |
|
The Dimension dialog opens:
|
|
3.Right-click the dimension-box a.Click Round and the Dimension becomes the nearest integer that is exactly divisible by the spin-increment value. b.Edit the Spin-Increment to be 1 c.Use the spin-box tool to edit the value to 16 |
|
(Please ignore the actual numbers in the data-boxes to the left). |
|
You have fully-defined the Circles: •the centers are coincident with Points in the Part •the Radii are equal; one is dimensioned 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. |
STEP 1: Click Solids Toolbar > Add Hole (above the graphic-area) |
|
You must click two elements to do Add Hole. 1.Click the prepared Circle in the Part 2.Click the Profile through which you want to cut the hole 3.Click Do 1-3 again to add the other Hole. |
|
•They cut through the Extrusion. •They are a brother (or sister) to an Extrusion and child to the Auto-Profile or Profile |
