3D Designing (TinkerCad Software)
About Lesson
We will see how we can use our workplane , Measuring options, Group and Ungroup feature, How hole shape is used, Aling shapes, Flip tools and Give colours to our designs,

Using the workplane

You would be surprised to know that the workplane we work can be temporarily moved. We can see in below images that blue workplane is our default plane and the orange workplane is the temporary plane. We have used this as we need some design on the angle shape, we have temporarily shifted our workplane to the angle to ease our design.
It is a better option than lifting an object with the help of cone, as we don’t need to measure, we just need to place the workplane. How to use this feature? Drag the workplane from the right-side top corner and place it when you want to work.


Measuring with the Ruler

We know as normal ruler is used for giving dimensions only, but here in tinkercad a ruler is used for extra work other than giving dimensions; such as we can identify the distance of origin. In below image, the green colour measurement indicates its distance from the origin in both X-axis and Y-axis.
Other three dimensions (20mm) are in X-axis, Y-axis, Z-axis, which can be changed by click on dimensions. The green mark dimension indicates the lift of the design from the workplane, currently, the 3D shape is resting on the workplane.       .

 Grouping and Ungrouping

As we move onto the complex design, we will be combing more and more shapes together. So, this combining of shapes called grouping. Let’s take an example, as shown below three different shapes has been combined together in two of the design. It can be done with a feature called group. But notice there are design one has been a group and another is not. So, the design has the same colour is been grouped and the design having different colour is ungrouped.
The ungrouping is done by feature next to a group called as ungroup. The design in different colour indicates that shapes are not combined together.


Using Hole Shapes


We have made lots of design using solid shapes now we will try our hand using hollow shapes or you can say hole shapes. As in the above image (i) we can see two cylindrical shapes. one is solid and the other one is semi-transparent which is a hollow shape. By this semi-transparent shape, we can make or generate holes in our design as required. The hole shape can be of any geometry as we first click on solid shape then a dialogue box appears of shape control, from where we can choose the option of a hole and make our selected design a hollow body.
Here in the second image (ii) we have reduced the size of semi-transparent cylinder and brought it to the centre of the solid cylinder, we have used group feature and combined two bodies. The hollow shaped will cut off the solid part and a hollow tube will be designed.
