CAD Tutorial: Draw a five-pointed star with Zhongwang 3D (2)

6. Click the [Predicate Entity] button under the [Modeling] toolbar, and the [Pruning Entity] property manager appears. The setting is as shown in Figure 1.8 (note that only one item is selected in the red rectangle). Click OK to enter the figure. 1.9 is shown.

7. Click the [Mirror] button under the [Tools] toolbar, and the [Mirror] property manager will appear, as shown in Figure 1.10. (For the next step, in the mirror step, you have to enter the optional input. Select to add the selected entity). After completion, it is determined as shown in Figure 1.11.

8. Click the [Pull] button under the [Modeling] toolbar, and the [Pinch] property manager appears, as shown in Figure 1.12. (When selecting Face 1, Face 2, Face 3, you must put this shape Flip to the bottom so you can choose). After completion, as shown in Figure 1.13.

9. Click the [Array] button under the [Tools] toolbar, and the [Array] Attribute Manager appears. Select the 'Circular Array' icon in the Array Mode icon and set it as shown in Figure 1.14. ([Array] Attribute Management The direction in the device selects the Z-axis negative aspect [red arrow place] when creating the datum using three points. If the plane 1 is centered, the magnified effect chart is as shown in 1.15, and a large arrow will be vaguely seen). After confirmation, as shown in Figure 1 (five-pointed star).

This example mainly uses the sketching in the 3D, the creation of the datum, the creation of the N side, the solid trimming, the mirroring, the shelling, and the array function, so that you can understand the combination of the surface and the entity more intuitively. Zhongwang 3D has a lot of good 3D solid modeling functions. It is much more convenient to use with the middle mouse button than other 3D software. If you have time, you can get a little more understanding and it will bring you unexpected surprises.
