I've really just been introduced to ETABS and I was wondering if it's possible to set up individual inclined gridlines within a system of orthogonal grids.
If you convert grids to a 'general' grid system, you can then use the Draw line tool (change from Frame type to Gridline) to draw gridlines in any skewed direction. CSI does a good job of adding useful features, many improvements in the past 3 years or so, but they do a poor job of documenting these features
You can also specify a diagonal grid system in Etabs by basically doing exactly what you would normally do in creating a rectangular grid system.
Simply go to edit grid system, create a new grid system (you can call it diagonal for ease of reference) then in the Edit Grid tab click on the "locate system origin" button and here you can specify the new origin and also the angle with which this grid system is to be located with respect to the global axis. Then just add gridlines as per normal.
Very easy to do and most helpful for those jobs with a diagonal grid system, best advice is to have a play with it to get the feel of it.
