Generate family instances with the rotation data Matrix = Matrix4x4(v,v,v,v,v,v,v,v,v,v,v,v,v,v,v,v)Įuler = euler_from_quaternion(rotation.X, rotation.Y, rotation.Z, rotation.W) Return roll_x, pitch_y, yaw_z # in radians

The custom python script extracts the block instance rotation in degrees from its 4x4 transformation matrix: import sys First retrieve the transform matrices form the block instances, and then extract the rotation angles in degrees from the 4x4 matrices using a python script. Speckle block instances also include a transform matrix that contains the information for the instance translation and rotation. Using the insertion points from the previous block, place your family instances by point and level.Įxtract block rotation angle from the instance transform matrices Then select the loaded family you want to use to generate instances, as well as the level to place them on. Place Revit families using the block instance insertion pointsĮach block instance includes an insertion point, which can be retrieved by running the code block below: Open Dynamo in Revit, and receive the blocks you just sent with a Dynamo Receive node. With Speckle installed for both AutoCAD and Dynamo, send your blocks to a Speckle stream. Get the rotation in degrees (from the 4x4 transformation matrix).Get the Speckle block instance transforms.Place the Revit family by point and level. Select the relevant loaded Revit family and levels for insertion.Get the insertion point of the Speckle block instances.

Switch to Dynamo in Revit and pick up the relevant Speckle stream.From AutoCAD, send the blocks to a Speckle Stream.To achieve this we need to do the following: So we need to map the AutoCAD blocks to loaded Revit families and place them in our model. The consultant sends their layout in dwg format and the architect would like to include the layout in their Revit model as 3D elements. Let’s take the scenario where an architect receives a furniture layout from an interior architect consultant. However, with an easy dynamo script, you can also map AutoCAD blocks to 3D Revit families directly! Speckle supports sending and receiving blocks in AutoCAD and Rhino, as well as receiving them as 2D generic models in Revit. You can follow him on Twitter or on LinkedIn.
