Aligning neighbouring paths and “connecting” anchors in Illustrator

I am working on isometric design that will be printed on the 1000mm x 2000mm Roll Up. Design includes lots of similar paths that should be perfectly aligned and create isometric 3d scene (image 1.)

enter image description here

I made diagonal guides (30° and – 30°) in order to create paths and aligned them together. It worked fine until I find out that some paths were not aligned as I wished and when zoom in the scene white gaps can been seen. Each path was created from original one (Alt key – Select the path) moved and aligned manually to the next neighbour.

enter image description here

However, now I am trying to find the best solution to adjust them and align perfectly without too much manual tweaking. Is there any way to automate the process and connect neighbouring anchors? I know there is a function in most 3D software named “connect vertices”, but is there something similar in Illustrator?

I am using Illustrator CS5 and CS6.

Thank you.

Method 1

I won’t directly answer the question, I will, instead suggest an alternate workflow. The benefit of this workflow is that it is guaranteed that you will not get this problem.

  1. First build a isometric grid. Make vertical lines and rotate the field 2 times with 120 degree offset. Tip: If you make the lines uncolored then you can just directly color the image.

  1. Then use the shape builder tool to make your shapes. TIP: When in shape builder tool you can assign colors to the fill and stroke, before dragging. That style will be put on the shape.

Now you are guaranteed never to hit and miss. Working speed is also most likely much faster.

Method 2

My way to align/join etc multiple points is as follows:

Press “A” and choose the points in question –

Now, right click and choose Average->Both:
