The only tricky thing is the use of fold_left to apply an anonymous (or lambda, for the LISPers out there) addition function across the contents of the list containing the individual volumes of the objects in the modelspace. As usual, committing is cheaper than aborting Seq.untyped_to_list ms |> List.map getVolume |> sumĮd.WriteMessage( ' Total volume: ' + vol.ToString()) And here's where we plug everything together.

The additional version of the software cover electrical wiring, and even architectural design. Use fold_left in a partial application to find AutoCAD is a good applicant for most technical drawing needs. | :? Solid3d -> (obj :?> Solid3d).MassProperties.Volume Let obj = tr.GetObject(x,OpenMode.ForRead) Note the valid use of tr, as it is in scope the volume of a 3D solid, if it happens to be one A function that accepts an ObjectId and returns Get appropriately-typed BlockTable and BTRs 'use' has the same effect as 'using' in C#ĭb.TransactionManager.StartTransaction() Let's get the usual helpful AutoCAD objectsĪ
