I've been working on this for about a half an hour (still getting used to the new LDD). I am only posting it now is so I can get suggestions on how I could make the head and legs and how to improve the elbows. Please give any suggestions and/or ideas you have.
I don't like how I made the elbows, but I can't think of any other ways. I need help.
I need suggestions on how I could make the legs and/or head.
Thanks for the recommendation ccy! When you are building any kind of mecha, it really comes down to how large you want it to be. That will dictate what pieces you use for joints. Do you have Universe mode unlocked in LDD? If you don't, then you might want to consider doing so, as it increases the amount of parts you have available. Now then, as to the actual building, when I'm building smaller-mid-sized mecha, I tend to go with the exo-force click joints, as they are versatile and fairly stable up to a point. Here is an example frame built primarily out of them: http://www.mocpages.com/moc.php/144429. (there are LDD files included for all my frames). As your mecha get heavier and larger, you will find that Exo-Force joints will tend to collapse under the weight, particularly the knees and ankles. At that point, you may want to consider using a frame with more heavy duty joints, such as this: http://www.mocpages.com/moc.php/145503. This one is good for most mid and mid-large sized mecha. If you find that your creations are getting even larger than this, there are alternatives, such as this: http://www.mocpages.com/moc.php/267172. There are methods to build even larger mecha (2-5 feet in height) but they involve techniques that are very hard/near impossible to achieve in LDD, so I tend to stick to the methods listed above. Try a variety of frames and joint types until you discover something you like! Thats my advice.
OK, since you add me as your favorite builder, let me give you a little suggestion. If you are lazy, you can find some exo-force joint as I using on my mecha creation. It will be much easy to assemble a frame for a mecha, not only elbows but the leg. About the head, it's not that easy to tell you how to build in a simple word but there are some people I know who have some LDD building instruction which can let you download such as : http://www.mocpages.com/moc.php/249373 or http://www.mocpages.com/moc.php/246506 or http://www.mocpages.com/moc.php/250405. They are all pretty good at LDD and you can even ask them directly. Try to join some mecha related group can also let you learn more. Keep going~
