An item is a decorative block that can go anywhere but you've made your item look like a road block for just that purpose. If you lay an original road block on a map then place the original block that connects to it. Select this second block and edit it by removing everything and starting from scratch. In the editor when everything is removed you're left with the clips to build your model off. Back in the days I use to do lots of video tutorials but I just don't have the time now. I loved the greative side of it and I'd like to say I preduced some of the best mods for Trackmania. 15 years later and I just have a dabble now and then these days.

If you look at my uploads you will see that they're named blocks and it'll show you which block I used and manipulated to create it.

If you download and try this block I made you might get the idea.

And btw you don't have to start from scratch. If you place your item ingame and go to edit it, from there you can export it. Then when you go to edit a block you can import it.

hmm... Starting to better understand, thanks. But not everything...

• so i can create a block (with clipping) by editing an existing block (variant), but there is no way to manipulate the clips inside the editor.
• as there is no existing block with inverted tilted clips, there is no way i can create my "bank to bank" item into one block, that's why you're speaking about creating two halves (the advantage of "bank to bank" being that it takes 64 units, not 128, i would have two 32 halves).

-> But there is also no existing block with a single tilted clip, so i would be left with an unused clip floating at the end of each half, if not in the way... And no way to get rid of it.

-> If i export as Crystal, the clips are removed, so this is not a solution

-> Are those "clip remover" i see everywhere of any use here ? I have no idea what they are for...

-> Do you think some good "customizer" could provide me with the two inverted tilted clips in a blank block ?

As for your last message, sorry i don't get what you're saying... ( If you place your item ingame and go to edit it, from there you can export it. Then when you go to edit a block you can import it.)

Can you message me your email address and I'll send you your item that I've tried making into a block. The block I use is the slanted to straight block but there is a way to make a block without any clipping but there isn't one that long. Your blocl should be 32 x 64 but I can only see 32 x 32 blocks without clippings.

Ah, nice ! I've sent you my adress in personnal message.

I'm curious to see what you've done... : )
