How to Draw a Lightbulb in Autocad

Steps

1

First of all, you will need a piece of paper. Any size of paper will be fine but it can't be too small. You will need something hard underneath the paper so you can draw easily. You will also need a pencil, maybe a rubber and some colouring pencils if needed.
2

Draw a circle-like shape similar to the one in the picture. It doesn't have to be exact. If you are really having troubles drawing it, you can trace it off your screen.

Next, draw two little \ and / on each side of the bulb as shown in the image and connect them with a curved line. Don't make the \ and / too slanted but not too vertical either. After that join the ends of the lines with a curve as shown in the picture. The curved line adds the 3D effect.
4

Draw two zigzags coming down from each side of the line vertically. It should look similar to the one in the picture.
5

Draw curved lines from one of the zigzags to the other. The lines should be parallel to each other and to the line you drew in step 3. Check out the picture below.
6

Draw a vertical line which goes down right the middle of the bottom part of the light bulb and a horizontal line on it. This is to mark the center for the next step. Draw a horizontal line on the vertical one about as far from the lightbulb as is on the picture. This is a marking to help with the next step.
7

Next draw a line from the end of the zigzag to the place where the two lines meet which you drew in the previous step. These lines should not be straight, rather a little bit curved towards the outside.
8

Erase the guidelines which you drew in step 6 and make the bottom of the light bulb slightly curved, not sharp.
9

If you want your light bulb turned off you can add some lines and shadows for special effects. Draw them near the edge of the light bulb. The second line (the inner line) should be shorter than the outer one. You can also add some shadow effects. Shade the inside of the light bulb right next to the edge. The closer it is to to the outside, the darker you should shade it. Only shade a little part though, not the whole light bulb, and only on one side, either left or right.
10

In this step you are going to draw the inside of the light bulb. You do not need to draw this if you don't want to because the light bulb looks good enough without it. However, if you do want to just follow this step. Draw a line that is relatively straight, but halfway up it bends to the outside. Draw two of these bending in different directions.
11

Next draw a wiggly/zigzag line connecting one of the lines you drew in the previous step to the other one. This zigzag should not have very sharp edges. You can also draw little loops instead of the wiggly/zigzag line.
12

If you didn't add shadows to your light bulb you can colour it in. If you do have shadows you can try this step to see how it looks but it might look very weird. To colour in your light bulb you will need yellow/orange and silver/blue. When colouring in the edge of the bight bulb, press a bit harder so it is a little darker while the very inside of the light bulb should be very lightly coloured. The silver/blue colour is for the bottom part of the light bulb. Don't colour it in too dark so that you can't see the curved lines you drew in step 5.
13

Admire the awesome light bulb you drew. It's great!

Question

Is this easy or hard to do?

This depends on how you intend to draw it. If you want to draw a basic, light bulb, drawing it only takes a few curves and an oversimplified version of the contents of the bulb. However, if you want to draw it realistically, it might become challenging.
Question

What is an easy way to draw a light bulb?

The method described in this article is quite simple.
Question

How do I draw a cartoon light bulb?

This lightbulb design can be adapted to make either a realistic depiction or an impression of the bulb. Try drawing a quick sketch of a light bulb and alter it to suit your style.
Question

How can I get the yellow glow?

Yellow watercolor paints would work. If you made it darker yellow in the middle and light on the edges, it would look perfect.
Question

How can I make it look like it is shining?

Draw a ring or a jagged line curving around the light bulb to indicate the light glowing.
