To ensure a good connection you need to be precise with your cursor.  To help you can try increasing the Snap Attach distance in Options | Snap | Snap Defaults.  The distance is measured in pixels so the optimal setting depends on many things including your screen size, resolution and personal preferences.  I find that values of 30-50 work best.

Use the Edit Node cursor (the second cursor button) to change the shape of objects - this will allow you to drag segments of doglegs to remove overlaps.

how to make well connected dogleg every time?

For now snap to grid and snap to connector are enabled. It seem to work 1 time for 5 try... (i try after to move the block to see if the wire follow the block)

And if the dogleg are one up each other how do you separe them? (to see them separatly)

Regard,

Fred
