To create an arc, select “Create” -> “Arc” -> “Tangent Arc” from the tool bar. This will create an arc tangent to two other entities. Left click on the vertex of where you would like the arc to connect. Then click on the other vertex to connect. Alternative to create arcs include 3-point arcs where you select the two vertex and the middle point of the arc or center point arc when the arc is create<ins>d</ins> by finding the center of the arc.

In order for a 2D sketch to be converted to 3D model, the 2D profile has to be a closed shape. This means all the lines and entities have to form a closed loop. This will be indicated with a light-blue shading inside the sketch.

=== Extrusion ===
=== Extrusion ===
The simplest way to create a 3D model is by extruding a 2D sketch, which adds a third dimension to the 2D sketch. Select “Extrude” from the toolbar. Hover the mouse over the sketch, closed shapes that can be extruded will be highlighted when hovered on. To select multiple shapes, left click on both shapes. In the extrusion settings that pops up on the right, enter the value for the third dimension of the sketch, the width. Click “OK” to confirm the extrusion.

You can select a new surface from the extruded object to sketch on. To do so, select “Create Sketch” and select the surface you would like to sketch on as the plane. Afterwards continue to sketch like normal.

Extrusion can also be used to cut. Sketch on the surface of the shape the geometry you would like to cut. Select “Extrude” tool and select the shapes you would like to cut. To remove material, enter a negative value in the dimension window. This indicates the direction you would like the extrusion to occur. On the screen, it will display a red region to indicate material removal. Press enter to confirm the operation.

=== Mirror ===
The mirror tool is an extremely powerful tool that can save the user a lot of time in creating the 3D models. This is especially useful when creating symmetrical objects. It allows users to mirror solid or small features. It does require the user to define the plane to mirror the features. There are many ways to create the plane. One of which is to “Offset Plane”

Under the “Construct” drop-down menu from the toolbar, select “Offset Plane”. Select a surface to offset from. This surface should be parallel from the plane you would like to create. Now enter the dimension you would like to offset the plane from the surface. Press enter when completed.

Filleting the edges is a feature that is offered in Fusion 360 and not TinkerCAD. It can easily elevate your models. It creates rounded surfaces by adding or removing from a solid model.
