Overview
In this tutorial you will learn how to build a 3D model of a flashlight using the revolve function, layer options, changing materials and colours and finally how to render the object.
The bounding box
Start by drawing a rectangle. The start coordinates will be (0,-25,0). Length will be 200 and width is 50. Now draw a line starting at (150,-25,0) going to (150,25,0). The rectangle acts as a bounding box, and the line is a guideline for drawing curves in the coming steps. Lock the first layer that you have drawn the rectangle in. Then switch to the second layer to proceed.
Hint: Use the panels tab to access the layers options like locking or visibility.
Do the same thing as with the body with the lens.
Hint: You can switch off the Visibility of the other layers by clicking the light bulb in the panels tab. This lets you see the lens a little better.
The Flashlight needs a button to be switched on. Go to the top view port. Activate intersection or near and end snap. Then activate another layer and type in sphere in the command prompt. Pick a place for the button and then define its size.
Hint: Using many layers helps keeping order and lets you define different properties to them like material or color.
You can rename every layer to your liking. Now that we set the proper names to all the layers we’ve created, we can start working on assigning materials and colours to the individual elements of your flashlight.
