Object Tracking used by itself or along with Temporary Tracking (TT) may take the place of your construction geometry. At a minimum it will save you time once you retraining your brain to use this approach.
Object Tracking: Object Tracking allows you to place new geometry or re-locate existing geometry by reference one to two points off of exiting geometry. This feature works with the Object Snap feature. Both features must be active (ON), the Object Snap(s) pre-set or (Running). Object Tracking references the pre-set Object Snap points and automatically activates when you hover the Cursor over the corresponding geometry a (+) appears to show where the cursor is tracking from. No selecting the geometry when you hover just let AutoCAD do its thing.
These features are found as a button in the Status Bar, toggle On or OFF, and also accessed through your function keys.
F3 = Object Snap
F8 = Ortho
F11 = Object Snap Tracking
(Objects Snaps were referenced a few weeks ago in a previous blog).
Temporary Tracking (TT): Temporary Tracking allows you to reference from an existing piece of
geometry out to a new point in space, then from that point to a second point. Key to this option is to type in the TT at the first point prompt.

Temporary Tracking, (TT) Placing a Rectangle referencing existing geometry for the first point out to a second point in space:
*Do not bring your cursor back over the (+) as that will remove it and you will have to start again.
*The default setting for Object tracking is to track off of 0ᵒ, 90ᵒ, 180ᵒ, 270ᵒ. If other angles are needed Polar Tracking can be defined.
