Find out how to use I-Borders and we’ll explain I-lines along the way. 

Just like connection lines, I-Borders are smart: 

If you move an I-Border, everything within, on, or snapped to it will move along.

  • Primary use is to indicate physical boundaries like an enclosure or the edges of a manifold. 
  • Use it also as a design tool to combine multiple components to move them efficiently as one while creating your project. 

How to summon + draw

You summon an I-Border by the icon in the sidebar, or right click and select ‘I-Border’. Then simply draw a rectangular I-Border with your mouse and left click to finalize. The I-Border changes from blue to red.

How to snap onto I-Border

When snapping on ports onto the I-Border, the line interrupts to take in the port so it really becomes part of it. This works the same for directional valves and sandwiches, or in this case joined ones: Simply bring them towards the edge and they will snap onto the I-Border.

How to resize I-Border

To resize an I-Border:

  • Left click anywhere on its line to select
  • Wait plus click again to lock to your cursor 
  • Resize as needed
  • Click once more to finalize its new measures

How to lock and unlock I-Border

Besides snapping ports or valves to I-Borders, you can also lock two or more I-Borders together:

  • Simply move one I-Border to another and they’ll automatically lock.
  • However, once locked, they act as one when you either move or resize one of them.

To move or resize separately you first need to unlock them.

To unlock them: 

  • Select one I-Border, 
  • Then select ‘release I-Border from other I-Border’.
  • Drag the selected I-Border to its new position. 
  • And left click to confirm.

Option in properties window

Now let’s have a look at the properties. 

  • Double click on a I-Border to open the properties window.
  • Here you can add information like an item number, manufacturer and Description, say a manifold.

The item number appears here in the canvas and the added information will also appear in the Bill of Materials. 

If you’re using I-Borders only to combine components, you might like the ‘hide in output’ option. Select it and your I-Borders won’t come up in your prints.

How to draw and group I-Lines

You probably won’t use this function as much as I-Borders but it’s a solution when you’re in need of a line to snap some ports to. 

You can also create non-rectangular odd shapes and sizes (as shown in the above video).

It looks like an I-border now... But to move it as a whole you need to group the I-lines together first. And beware, Like an I-Border, you can snap certain components to it. Even when grouped together, components inside won’t move along.

How to resize I-Lines: stretch function

Last, resizing works slightly different than resizing a standard I-Border, you’ll be needing the stretch function:

  • Start with dragging a box from right to left to select the edge you wish to resize.
  • Then right click that edge and select the stretch function, or use its short key [Shift + S].
  • Now click on the selected edge again, drag it to its new position and finally, left click to secure.
