In Altium Designer I want to connect multiple wires in one junction but program doesn't allow me to do that and when I move to any components, wires get triangular shape. I want to just 90 degree movement of wires. I looked the schematic preferences and couldn't find correct settings.

Which setting parameter is for this purpose?

Here is a example what i mean

  • \$\begingroup\$ I want to connect multiple wires in one junction <--Connecting multiple wires (more than 3) to one junction is bad practice. \$\endgroup\$

  • \$\begingroup\$ Drag mode is set with SPACE (while dragging). \$\endgroup\$ Jan 14, 2023 at 16:09
  • \$\begingroup\$ To avoid the angled wires you circled above the Ground connection, move the Ground symbol left or right to avoid the four-way junction. You should avoid four-way junctions as they can easily be misunderstood to be wires crossing without connection. \$\endgroup\$ Jan 14, 2023 at 17:02
  • \$\begingroup\$ Regarding the 90 degree wire , as much as I remember you can press space while holding the wire to change the angle of wiring \$\endgroup\$

  • \$\begingroup\$ Shift-spacebar will toggle 90, 45, any angle modes. \$\endgroup\$

Altium converts your junctions for a reason. Cross junctions are difficult to interpret, especially when printed and possibly photocopied.

You can manually place your connections to avoid cross junctions, for example by moving your ground connection:

You can change "Convert Cross-Junctions" setting in the schematic preferences.

$-Way wire junctions are a BAD idea. If you are working the computer, you are probably zoomed in far enough to see the junction. If you are working on a printout that has been reduced in size (from D to A), there is a good chance that the junction will not be visible. You can 't tell whether the wire is just crossing the other wire or if there is a junction. DON'T USE 4-WAY CONNECTIONS!

Remember, the schematic exists for 4 people.

  1. The person drawing the schematic so they can put there thoughts on paper and design the circuit.
  2. The person that is laying out the board.
  3. The poor bastard that has to fix it.

Avoid ambiguity.
