2. Getting Started with OneSpace Designer

3. What is a Work Plane? A Workplane is like a transparent drafting board. Workplanes are shown with a border to help you see where it is at all times. However the border does not mark the boundaries of the workplane because workplanes are infinitely large. You can create 2D profiles on a workplane. A workplane and profile can combine to make a tool. You can use a tool with a machining command to create or modify a part.

4. What is a Work Plane? continued A workplane can be positioned anywhere in space. Each workplane has its own local coordinate system that moves with the workplane when you position it. This is called the UVW coordinate system. You can create profiles only on the active workplane. You can have multiple workplanes, each located at a different point in space and each with a unique profile.

5. Creating a Workplane By default new workplanes are located at the CAD system origin.

6. Creating Geometry on a Workplane Commands for creating profile geometry are found in the Create 2D menu 4 types of geometry can be added to a workplane Straight: linear geometry including lines, polygons, rectangles. Construct: construction geometry (infinite lines, circles, and points) that are used as guidance when creating “real” profile geometry. Circular: circular geometry, circles and arcs Contour: contour geometry, including splines and ellipses, but also equidistant, cross sectional, projected and overdrawn geometry.

7. Creating Geometry on a Workplane continued The Straight, Circular, and Contour menus can be used to create finite geometry. The Construct menu, by comparison, is used to create infinite lines. You can affect how geometry is displayed on the workplane and how workplanes are displayed in the viewport by using the Show menu. Edit -> Settings -> Show Settings -> Workplanes

8. Creating Geometry on a Workplane Exercise 1.Click Create 2D in the main menu - Straight is automatically selected 2.Make sure Geometry is switched on in the Straight menu 3.Click Polygon at the bottom of the menu. 4.Specify the first point of the profile by entering 0,0 on the command line. 5.Click Horizontal in the Polygon option box, and click the other end of the profile’s lower line. 6.Now click Vertical and create a long vertical line. 7.Continue drawing the profile’s external geometry. The final segment is created by clicking Close in the Polygon menu. When you are finished click OK, the green “check”. 8.Now click Circular in the Create 2D menu. 9.Click Ctr & Rad in the Circular menu. 10.Click a center point for the circle in the viewport, and then click a point on the circle to imply its radius. 11.Click OK in the Circular menu. 12.The profile should look like the following:

9. Creating Solid Models – Machine Menu Commands for machining profiles and parts are found in the Machine menu. The two machining operations that can be applied to profiles are: Extrude: creates a part by extruding the profile by a given distance or up to another object, such as a part or a face. Turn: created a part by sweeping a profile around a specified axis. For both of these machining commands the profile must be closed. These and the Unite and Reflect commands can be used to add material to existing parts. For example, Extrude can also be used to add a boss to an existing part.

10. Creating Solid Models – Machine Menu continued A number of machining commands remove material from existing parts. Command such as Mill and Punch use a profile on a workplane to define the material to be removed. Other, such as Subtract and Intersect, use a tool part in conjunction with a blank.

11. Creating Solid Models – Machine Menu continued You can affect how solid models are displayed in the viewport: The Shaded switch in the Show menu turns on and off shading of the part’s faces. The Wire switch in the Show menu turns on and off the display of the facets of which the part is composed. The Hidd Supp switch in the Show menu turns on and off the display of the hidden lines in a part. When this is on you can also use Hidd Dimm to display the hidden lines dimmed.

12. Creating Solid Models – Exercise 1.Use the profile you created in the previous exercise (3 slides back) for this exercise. 2.Click the Machine menu in the main menu. 3.Click Extrude in the Machine menu 4.In the Part data field, enter the name simple_part. 5.The Workplane field is already filled in, W1, as this workplane is active and contains a valid closed profile. In general, if this field is not filled in automatically, it implies that the active profile is not valid, and must be fixed before it can be machined. 6.The Extrude method is Distance by default, and the Distance data entry field is yellow meaning that this information is required.

13. Creating Solid Models – Exercise continued 7.Enter 2 in the distance data entry field. Notice a green preview appears. 8.Leave the Direction (+W) at its default, and also the two switches that offer you the option to keep or discard the workplane (Keep WP, checked) and profile (Keep Prof, unchecked) at their defaults as well. 9.Click OK in the Extrude menu. The green preview turns gray indicating a solid model was created and the Extrude menu disappears.

14. Modifying Solid Models – Machine Menu Machining commands can be used to add or remove material from existing parts: Mill is used to remove material that lies within a profile a specified distance. Punch works similarly to Mill but removes material within a profile an infinite distance in both directions. Stamp does the inverse of Punch, removes material outside the profile. Bore sweeps a profile around a specified axis like Turn, but Bore removes material.

15. Modifying Solid Models – Machine Menu continued Shell is used to provide solid models with uniform wall thickness. Unite adds parts to an existing part or adds parts together to create a new part. Reflect reflects one or more parts to create a single resulting part Subtract is used to modify a blank by subtracting a tool from it. Intersect modifies a blank by keeping only the material that is common to both the tool and the blank. Section allows you to see the inside detail of a part or assembly.

16. Modifying Solid Models – Exercise Creating Workplanes on a model Use the simple_part you created in the previous exercise (4 slides back) for this exercise.. Click Workplane in the Main menu. Click New in the Workplane menu. The Create New menu displays the default name of w2 and the default owner of root or / (slash).

17. Modifying Solid Models – Exercise Creating Workplanes on a model Click Par to Face to expand the Create New menu. Click the vertical face.

18. Modifying Solid Models – Exercise Orienting Workplanes on a model Click Slide Origin; this will relocate the origin of the workplane, selected arbitrarily when you clicked on the face to known point on the face. Click the bottom left point of this face. Click OK in the Create New menu. The new workplane automatically becomes the active (green) workplane, as shown in the Active @P display fiedk at the bottom of the screen. Create a simple profile on the workplane: Click Create 2E” the Straight menu also opens/ Click Rectanglee, and draw a rectangle within the part’s face as shown/ You can position the view at any time to help you see wha tyolu are doing. Tis doen net interrupt the action. Click Machine in the main menu. (The Straight menu closes automatically: OD is assumed.) Click Punch in the Machine menu/ The Part display field shows the mane simple_part and the workplane filed shows W2. This is because bot a re active and the workplane contains a closed profile Click IL in the Punce menu to accept the data. The prokfiel sweeps throuth the medel in the workplane’s mormal direction and temeves the defined volume

19. Modifying Solid Models – Exercise Orienting Workplanes on a model Click U Dir, this will allow you to specify the direction of the U axis of the new workplane. The Direction 3D Menu will appear. Click Edge Tangen and then click the lower edge of the highlighted face. Click Accept.

20. Modifying Solid Models – Exercise Orienting Workplanes on a model All of the required information for the creation of the new workplane has now been entered. Click OK (green check) in the Create New menu. The new workplane gets created, its origin is at the lower left corner of the face and the U axis is in the direction of the lower edge. The new workplane, W2, becomes active and its border turns green. The old workplane, W1, becomes inactive and its border turns purple.

21. Modifying Solid Models – Create Profile Create a simple profile on the workplane: Click Create 2D; the Straight menu also opens. Click Rectangle, and draw a rectangle within the part’s face as shown. You can position the view at any time to help you see what you are doing. This does not interrupt the action.

22. Modifying Solid Models – Machine Profile Click Machine in the main menu. Click OK in the Punch menu to accept the data. The profile sweeps through the model in the workplane’s normal direction and removes the defined volume. Click Punch in the Machine menu. The Part display field shows the name simple_part and the Workplane field shows W2. This is because the part is active (green edges) and the workplane is active (green border) and contains a closed profile. End of GETTING STARTED session
