Four way conveyor intersection

Hey everybody.

I am working on a conveyor model, and have hit a snag.

The conveyor system has two directions side by side, and in some places, there will be 4-way intersections, where each item can go in one of four directions. (Counting a 'U-turn').

I had initially hoped that simply crossing the conveyors would create transfer points, but that doesn't seem to be the case, unless I am missing something.

I suspect thwere is some obvious answer for this problem, but I just haven't found it yet.

Is there anyone out there who has tried something similar, and who has any experiences to share?

Best regards

Christian

Can you not begin with default behavior?:

Hi Jason.

Using default behavior seems like a brilliant plan. This works exactly as I intended.

I don't know why it didn't work for me earlier.

Thanks a lot.

This is more tricky than it appears - you need to precisely align all the conveyors which is almost impossible interactively using the mouse - even with snap threshold lowered. I did it by increasing the displayed decimal precision in model settings and then changing the properties fields. A better way might be to write a script to construct the layout precisely.

I agree, it is tricky, and I have realise that the alignment issue is why it didn't work in my initial model.

I will work on a script solution to place the intersection along with 1 meter of conveyor on each of the four sides.

Thanks again.

@Christian Wordenskjold , you can start with your roundabout crossing section.
