 ===== How to Create a Lego Piece=====
 \\
+Creating a new lego piece can be the most difficult part of the project. In order to create a lego piece, the best way to do it is by copying what the other's did.
 \\
-**Video**
+The most important aspect of creating a lego piece is that it needs to be 100% compatible with other pieces in the folder.
 \\
+This is why one must use measure tool to examine the correct size of holes and lengths to make sure that all sizes match with others.
 \\
-Open the parts from your folder.
 \\
-Make sure to get the motor first!
+For this tutorial, the following 1x4 red block with a hole in the middle will be created.
 \\
-This is important as this is the piece that will be stationary (fixed)!!
+{{:lego:tutorial:lego-red-technic-brick-1-x-2-with-hole-3700-32-64503-81.jpg?400|}}
 \\
 \\
-**Step 2**
+A simple 1x4 pink block piece and green 1x3 technic piece will be used as a guideline.
 \\
+{{:lego:tutorial:comb2.png?400|}}
 \\
-Open the "peg" that rotates inside the motor. Assemble it to the motor first.
 \\
-{{:lego:tutorial:f7.png?400|}}
+**Step 1**
 \\
 \\
-**Step 3**
+Open up a file that is closet to the piece that you are creating.
 \\
+Study how the piece work and see the dimensions on how the piece fits with others.
 \\
-Assemble the rest of the parts.
 \\
-Make sure to use gear mate for the gears.
+**Step 2**
 \\
 \\
-**Step 4**
+Create a copy of the file you are creating to mimic and start editing it. This is the fastest way to do it.
 \\
 \\
-Watch the assembly video.
+**Video**
 \\
-Make sure to have captions on for the tips.

 \\
+Try to use the sketches that are already present to save time.
 \\
+Make sure to use measuring tool to match the dimensions of the dimensions of other pieces.
-===== Result =====
 \\
-If you did everything right, the result will look like this!

+**For pieces that are totally new**
 \\
-The name of the files and folders are important because that is how DASL wiki displays correct image/files.
 \\
-If the link is in <fc red> red</fc>, then it means that the link is broken and you should see if you uploaded  the file in the right folder or the name is correct.
+{{:lego:tutorial:wing.png?400|Stuff}}
+\\
+For unusual pieces like this, you need to use caliper to measure the rough dimensions of it.
+\\
+Once the measuring is done, make sure to compare the sizes with other pieces so that it fits with it.
+\\
+Having a uniform size is the most important aspect when creating a new piece.
