Its a design I did a few years ago before I learned a lot of tricks for making great legoformers maybe he deserves a V2 ... and some friends!

It is awsome... I think you should make others from Hearts Of Steel like megatron bemblebee the insecticon battle train and shockwave

Thanks! Glad you like it but I use LDD mostly for throwing around ideas I rarely use it first then build something in the brick! So this HOS Prime was just a concept I was toying with. Usually I prefer the old fashioned way of building just me the radio my large inventory of bricks and my creativity.

Dude, this is awesome. I didn't realise so many people were aware of Hearts of Steel! How do you resist the urge to impulse-buy parts from bricklink every time you make an LDD TF? I've got bugs under my skin, man.

I know how he got all those unavailable pieces. he is using lego universe LDD like when you go to the page it has 3 choices at the home page and you can make any piece any color so that is how. but you cant buy things from this option. awesome model:)

Dude, Nice!!!

Very cool! I like the lance!

you couldn't if you wanted to, many of the colours and elements in this design are not available from pick-a-brick.

You read my mind. Early this week I was looking at the toy story army men and thinking I should do some GI Joe vehicles. And the Cobra HISS was one of them. Maybe I'll do GI Joe MOCS when I get tired of Transformer MOCS.

Have you ever considered doing the H.I.S.S. tank version of Optimus, from the G.I. Joe vs. Transformers comic series?

AWSOME SAUCE!

This is awesome! Question, how did you get some of those bricks and colors? The hip pieces aren't even available in the LDD program I use.

Which version of LDD do you have? It didnt work for me and deleted half the bricks and turned him brown :[

WOW! I've never heard of Heart of Steel, but this is an awesome idea for an Optimus model! Great job, as always.

Awsome!!! Also, how did you find the joints for the legs on LDD? I looked everywhere on LDD and I couldn't find those type of joints. How did you find it?

Wait a sec. how did you did get all those pieces in dark red?

Mad Props for this one!

This is so cool! I really like how it Transforms and you've presented it really well!

This is a really cool Prime concept. I never thought of him as a train. I think I'll have to build it just because. Thanks for posting the LDD with it!

You could modify it to match the pieces you have.

I am not a big fan of LDD either but I have CAD background from early in my career so its comes easy to me. I still like building in reality over virtually. But this way its less mess in my workshop. LOL! Not sure if I am going to build this in reality or not yet!

This is awesome! I can't deal with LDD at all, it's a mystery to me how you were able to create such a great transformer on the computer. Are you going to build it in real life?

Very nice! I can't build it sadly.
