Have you seen people talking about LEGO® MOC and wondered what they are or maybe you know what one is, and you are not sure how to make one yourself?
A normal LEGO® set is produced by The LEGO® Group, and a LEGO® MOC is produced big or small by anyone else and is not officially released unless done so through the LEGO® Ideas platform.
What Are LEGO MOCs
What does MOC stand for?
MOC stands for ‘My Own Creation’ which is a term used by LEGO® artists and designers when creating unique custom designs. It has officially been used since 2007 and is not to be confused with similar fandom creations such as OC or Original Character which are terms describing fan-made characters.
What’s the difference between a LEGO® MOC and a LEGO® set?
A MOC (or My Own Creation) is a LEGO® set that has been created by a non-LEGO represented or employed person.
Typically when you buy an official LEGO® set it will be in a nicely designed box or poly bag, when buying a MOC it will normally be electronic consisting of an XML or IO file which is used to purchase the LEGO® bricks, and a PDF containing the instructions.
How to build a LEGO® MOC
If you love LEGO® and have a creative mind you should give it a go at making one. To do this you will need the following:
- A computer or laptop
- LEGO design software
- Time and patience
What software do I need for a LEGO® MOC?
There are two main pieces of software you can choose from to use, both are freeware so feel free to give them both a go and see which you prefer. I personally prefer Stud.IO but that’s just me…
Lego Digital Designer
(produces .LDD files) which was developed by the LEGO® Group.
Stud.IO (produces .IO files) which was developed by BrickLink.
What can I do with my LEGO® MOCs?
It’s up to you what you do with your LEGO® MOCs, a few suggestions are:
- Make them for fun or as a hobby and that’s it
- Create a social media account on Flickr, Instagram, or Facebook, and post pictures of your designs.
- Post them on social media and list them on Belle-Ve Bricks website to make money
from your hard work.
