Which aircraft with which panel?
Which airport ?
Which runway ?
Which ILS frequency ?
Normal ILS intercept altitude is about 1,500 feet above the airport elevation. As you note, in Flight Simulator - it is critical to be below the ILS glide slope when engaging the Autopilot APPR button/ mode.
There may be some individual variations to the standard rules based upon aircraft, panel, airport, runway or ILS frequency - that's why I asked for that info.
