What do I need to show on a door detail drawing?

Hi, Could do with a little more info on your project as details can be added, but it depends who the drawing is for. Maker, Planning,Tender etc. If you are drawing a General Arrangement for a workshop, this is a build drawing this would be at a 1-1 scale, to allow the workshop to lay the drawing out full size. If the drawing is for approval, then you may find a 1-10 scale with 1-1 detail boxes as a better layout. As far as key info, I like to include: Structural opening, Overall Frame width/height/depth. Door Width/Height/Depth. Rebate sizes in the frame. Panel to cut sizes. Glass Size and specification i.e toughened, wire. Intended Ironmongery is useful Threshold detail Intumescent sizes/groove detail Fire rating 30/1hr etc Hope that gives you some idea, but the list is not complete, as I mentioned it depends on the purpose of the drawing. You may find it useful look up door drawing layouts online and utilise the info there too.
