Add Profile

Solids toolbar > Add-Profile adds a Profile to a sketch-loop in a Part.

You must add the sketch-loop to the Part before this command.

Profile and Extrusion elements

A Profile has two contours that are offset from each other – the Primary-Contour and Secondary-Contour
The Extrusion is a child to the Profile. It is the Solid that fills the gap between the two contours that define the Profile

The Extrusion element has parameters that you edit with the Extrusions dialog-box:

Parameters: Colour, Transparency, Density.
Dimensions: Part Offset, Extrusion Offset, Extrusion Depth

The Profile contours are pink

They are in front of the sketch-loop.

You can edit the colour of the Profile contours in Application Settings | Colours tab.

The Profile and Extrusion in the Assembly-Tree

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

Part1s-red
The Profile2s or Auto-Profile if you have used the Auto-Profile[s] command] as a child to the Part
The Extrusion3s as a child to the Profile

To show the Extrusion in the Mechanism-Editor use :

Visibility toolbar > Show Model in Mechanism.

QST4-1-1

The Profile and Extrusion in the Graphic-area

The Profile has two contours. The Primary Contour1s-red and Secondary Contour2s.


Use the Extrusion dialog-box to edit the:

Distance to the Secondary Contour from the Primary Contour ( Extrusion Depth )
Distance to the Primary Contour from the Mechanism-Plane (and sketch-loop3s).

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

The offset distance is along the Z–axis4s

QST4-1-2

The Extrusion:

'fills' the space between the 'Primary Contour' and 'Secondary Contour'.
has properties: Colour, Transparency and Density.

Edit its properties in the Extrusion dialog-box.

STEP 1: Click the new Mechanism name-tab

Then, to start the Part-Editor:

STEP 2: Double-click the Part-Outline
- or -
Double-click a sketch-element that is a child to the Part

QST4-3-6

STEP 3: Click Add Circle1s-red in the Geometry toolbar

Add two Circles. Use these two techniques.

TECHNIQUE 1

1.Hover above a Point2s, so that it becomes red
2.Click and Drag the radius of the Circle.

The centre-Point 'snaps' to the Point2s when you release your mouse.

TECHNIQUE 2

1.Drag the Circle near to the Point3s

Icon-SE-Coincident

2.Add a Coincident Constraint between the centre-Point of the Circle and the Point3s

Icon-SE-Equal

Icon-AddDimension

Add a dimension and constraint to the Circle:

STEP 4: Click Add Equal Constraint in the Constraints toolbar [to the right-side of the graphic-area]
STEP 5: Click the two Circles
STEP 6: Click Add Dimension and Click a Circle
STEP 7: Click again to place the dimension

Dialog-Dimension-EditDirectly

The Dimension dialog-box opens:

STEP 9: Enter a Dimension.

 

- or -

Dialog-Dimension-Round-131.409

STEP 10: Right-click the dimension box

Click 'Round' to force the Dimension to the nearest integer that is divisible by the spin-increment value.

Use the spin-box tool to edit the values.

[Ignore the actual numbers in the data-boxes to the left].

QST4-3-7

You have fully-defined the Circles:

the centres are coincident with Points in the Part, and
the Radii are equal; one is dimensioned

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

STEP 11: Close the Part-Editor – Double-click a sketch-element.

Use the Circles to add Holes through the Extrusion.

Icon-AddHole

STEP 12: Click Add Hole in the Solids Toolbar [above the graphic-area]

CM-AddHole-1

You must click two elements to complete Add Hole. See the Command-Manager.

STEP 13: Click the Circle (or a sketch-element in a sketch-loop) in the Part to become the Hole
STEP 14: Click the Profile through which you want to cut the hole
STEP 15: Click OK

Do Steps 12 to 15 again to add each hole.

QST4-1-3

Holes2s:

The shape of the hole is also a sketch-loop1s-red.
They must be 'inside' the sketch-loop that you use for the Extrusion or Auto-Profile.
They cut through an Extrusion.
They are a brother to an Extrusion and child to the Profile or Auto-Profile.
