Form a 15mm Cube and Tap with your Finger on one Face:
On the last image above create your layout appropriate to the Number required on that Face.
For simplicity and speed #4 has been chosen the ‘dimples’ are 4mm diameter.
Divide each Circle with a Line as shown
Tools > Revolve Tap on the lower half of 2 Circles, choose the upper or lower pair, as shown.
Then Tap on the centre Line of one of the chosen Circles.
Tap on the 360º Label and Change it to 180º.
Repeat with the remaining pair of Circles.
For you own confidence Tools > Color and slide the Transparency, far right centre, to expose the Half Spheres:
Select ALL the Edges of the Cube as shown.
Then drag the double Ended Arrow outward to 15mm or type in 15mm as you wish, experiment with this dimension it is free and fun:
Tools > Subtract to be Subtracted From > Select/highlight the Cube > Next > Select/highlight the 4 Half Spheres. These Selections are best carried out in Items.
If you work with Items open while Designing you will become aware of the ‘naming’ of your individual creations. Anything Selected/Clicked On in Items will highlight on the Design:
At this point you have one of the 6 Faces needed for the finished article.
Repeat the above 5 more times using the appropriate Numbers.
However it is a good idea to think about the possibilities of Copying, say #3 then delete the 2 ‘dimples’ furthest from the centre to leave #1. Or perhaps add a #1 to a #4 to get #5. The possibilities are not endless but certainly worth consideration.
