My windows all have multiple muntins, and all are operable casements.
- The opening elevations don’t show muntins.
Also 2) operability lines don’t always show up (all these windows are operable casements) and are backwards . (The convention I am using is that lines showing operability converge at the hinge side but these lines – if they are intended to indicate operability – are the opposite. This may be a european standard. But I’m in N America, so it’s backward.)
