Topic Tutorial Whiffle Ball (Part Module) Beginner Not provided r-frank 0.16.6703 [1] Whiffle Ball

### Introducere

Acest tutorial este aici pentru a vă învăța cum se folosește Atelierul Part Workbench. Veți exersa:

• inserare primitive geometrice
• schimbarea valorilor primitivelor
• utilizarea plasamentului
• realizarea de operații booleene

This tutorial was originally written by Roland Frank (†2017, r-frank), and it was rewritten and illustrated by vocx.

This tutorial is here to teach you how to use the Part Workbench.

The Part Workbench was the first workbench developed. It provides the basic geometrical elements that can be used as building blocks for other workbenches. The Part Workbench is meant to be used in a traditional constructive solid geometry (CSG) workflow. For a more modern workflow using sketches, pads, and features, use the PartDesign Workbench.

You will practice:

• inserting primitives
• changing parameters of those primitive objects
• modifying their placement
• doing boolean operations

5. The previous operations create a smaller cube inside a bigger cube. To visualize this, we can modify the View properties in the property editor.

5.1. Select `Cube001`, the smaller cube, in the tree view, and change the color. In the View tab, click on the Shape Color value to open the Select color dialog, then choose a green color; also change the value of Line Width to `2.0`.
5.2. Select `Cube`, the larger cube, in the tree view, and change the transparency. In the View tab, change the value of Transparency to `70`.

Solid cube inside another solid cube

## Insert primitive cylinders

6. Insert a primitive cylinder by clicking on .

6.1. Select `Cylinder` in the tree view.
6.2. Change the dimensions in the Data tab of the property editor.

8.2. Open the Placement dialog.
8.3. Change X to `-60 mm`.
8.4. Change the Rotation to `Rotation axis with angle`; Axis to `Y`, and Angle to `90 deg`.
8.5. Press the OK button to close the dialog.

## Change visual properties

9. The previous operations create three cylinders that intersect with each other, and also intersect the cubes. To visualize this better we can modify the View properties in the property editor.

9.1. Select `Cube001`, the smaller cube, in the tree view, and change the transparency. In the View tab, change the value of Transparency to `70`.
9.2. Select `Cylinder`, in the View tab, click on the Shape Color value to open the Select color dialog, then choose a red color.
9.3. Select `Cylinder001`, in the View tab, click on the Shape Color value to open the Select color dialog, then choose a blue color.

Solid cylinders that intersect themselves and the solid cubes.

## Fuse and cut

10. In the tree view, select `Cube001` (the inner, smaller cube), and the tree cylinders, then press . This will create a `Fusion` object.

11. Then perform a boolean cut of the `Cube` (larger cube) and the new `Fusion` object.

11.1. In the tree view select `Cube` first, and then `Fusion`.
11.2. Then press . This will create a `Cut` object.
Note: the order in which you select the objects is important for the cut operation. The base object is selected first, and the subtracting object comes at the end.
11.3. If the colors look strange, select the new `Cut` object, go to the View tab, click on the Shape Color value to open the Select color dialog, then choose a gray color; also change the value of Line Width to `2.0`.

Hollow shape produced from cutting a cube and three cylinders from a bigger cube.

## Insert primitive cubes to cut the corners of the partial solid

Now we'll create more cubes that will be used as cutting tools to trim the corners of the previously obtained `Cut` object.

13.4. Change Height to `180 mm`.
13.5. Open the Placement dialog.
13.6. Change X to `-90 mm`.
13.7. Change Y to `-90 mm`.
13.8. Change Z to `-90 mm`.
13.9. Press OK.

We'll duplicate the previous two objects again to use once more as cutting objects.

14. Select only `Cube002` in the tree view, and go to Edit → Duplicate selection. This will create `Cube004`.

15. Select only `Cube003` in the tree view, and go to Edit → Duplicate selection. This will create `Cube005`.

16. To visualize this better we can modify the View properties in the property editor.

16.1. Select the `Cut` object, in the View tab, click on the Shape Color value to open the Select color dialog, then choose a blue color.
16.2. Select all new cubes, `Cube002`, `Cube003`, `Cube004`, and `Cube005`, in the View tab, change the value of Transparency to `80`.
