Shaft Definition Dialog Box
This section describes the various options available in the
Shaft Definition dialog box to create a shaft.
Thick Profile and Thin Shaft Selecting the Thick Profile check box
expands the dialog box, giving you access to the Thin Shaft options. These options allow you to add thickness
to both sides of the profile used to create the shaft.
In the example below, the shaft is created using the Thick
Profile option. Selecting this option opens the whole
Shaft Definition dialog box, which lets you then define
Thickness 1 and Thickness 2.
Initial profile
Resulting shaft
The profile is previewed in dotted line. Thickness has been added
to both sides of the profile.
Neutral Fiber: The Neutral Fiber option adds material equally to both
sides of the profile. The thickness defined for Thickness
1 is evenly distributed to each side of the profile.
Merge Ends: The Merge Ends option attaches the profile endpoints to
adjacent geometry (axis or if possible to existing material) as
illustrated below:
Resulting shaftThe profile has been attached to the axis.
Using Thick Profile you can create shafts
from open profiles but you cannot use the Merge Ends
option.
About Profiles/Surfaces
This section provides information on the profiles/ surfaces used to create a
shaft.
ProfilesYou can:
- Create shafts from sketches including several closed profiles.
These profiles must not intersect and they must be on the same side
of the axis.
- Define whether you need the whole sketch, or sub-elements only.
For more information, see Using the Sub-Elements of a Sketch.
- Use open profiles in geometrical sets provided you create a thin solid.
- Change the sketch by clicking the box and by selecting another
sketch in the geometry or in the specification tree.
-
Use any of these
creation contextual commands available from the
Selection box:
- If you have chosen to work in a hybrid design environment, the geometrical elements created on
the fly via the contextual commands mentioned above are aggregated
into sketch-based features.
- You can also edit your sketch by clicking the icon that opens the Sketcher workbench. Once you have
done your modifications, the Shaft Definition dialog box
reappears to let you finish your design.
- If you execute the Shaft command with no profile
previously defined, just click the icon and select a plane to access the
Sketcher workbench, then sketch the profile you need.
- You can use wireframe geometry as your profile and axes created
with the Axis System command. For more information, see Generative Shape Design User's Guide: Using Tools: Defining an Axis System.
SurfacesYou can create shafts by selecting a surface as illustrated in this
example:
About Axes
You need to define a axis while creating a shaft.
You can select axes from the geometry area, not from the
specification tree. Additionally, keep in mind the following
recommendations:
- When the selected sketch both contains a profile and an axis,
the latter is selected by default as the revolution axis.
-
You can
select an axis belonging to a plane distinct from the profile
plane. Just make sure that the axis does not intersect the
profile.
-
Contextual commands
creating the directions you need are available from the
Selection box:
- Create Line: For more information, see Generative Shape Design User's Guide: Creating Wireframe Geometry: Creating Lines.
- X Axis: The X axis of the current coordinate system
origin (0,0,0) becomes the axis.
- Y Axis: The Y axis of the current coordinate system
origin (0,0,0) becomes the axis.
- Z Axis: The Z axis of the current coordinate system
origin (0,0,0) becomes the axis.
If you create any of these elements, the application then
displays the corresponding icon in front of the
Selection box. Clicking this icon enables you to edit the
element.
