New to LDD designer

[Russell1982]

Greetings all. My name is Russell and I have recently (rather foolishly) decided I would like to build my own lego tank and so with this aim in mind I downloaded LDD and have begun playing around.

after about 30 minutes I decided I would try and re-create Pawel "Sariel" Kmiec's (apologies for lack of correct type) studless transverse subtractor from his book "The unofficial lego technic builder's guide".

sadly I have run into an issue after the first stage, where I am trying to install the differential inside the square brick and couldn't but eventually figured this out, however I the discovered I could not get the program to allow me to put all three conical whel gears into the dif. I will attempt to insert a picture to illustrate this.

is this something that I am doing wrong or is it a bug issue? any assistance and advice to me would be very much appreciated

I have just discovered that you are required to rotate the gears to make them mesh so have resolved this issue but advice is still very welcome

I've built extensively in LDD, spent hours tweaking angles and turing things inside out. You'll find the program can be a little quirky at times. My advice is to just move on. Don't get hung up too long on specifics, it can hinder the creative spirit.

The conical wheel is 12 teeth. So just place the middle one first. and hinge(rotate) it 15 degree (360 / 12*2 = 15). Then you can place 2nd and 3rd wheels.

Agreed. I should have pointed out what I was trying to say a little better. Sometimes when you fidget with a piece forever, then save, the program will reject it when you reopen it. I've just found that it is easier to assume a few things to keep the mojo flowing.
