Hello everyone, I have a script that creates a 3D model of a metallic structure, creates section views of certain areas (and duplicates the default 3D View) of the model, sets the scale according to the sheet size and inserts them into the created sheets. It then proceeds to export the sheets into a PDF file using PDFCreator. However, a part of the 3D model ends up being cropped out of the viewport in the duplicate 3D View (as shown bellow - the Crop View is visible): [image] Is there a way of setting up the Crop View automatically in a way where the 3D model isn’t cropped? All files are available bellow for your criticism and any improvement (even regarding other topics) is welcome: bars.xlsx (57.5 KB) nodes.xlsx (30.1 KB) structureV24.dyn (2.4 MB) Template.rvt (3.3 MB)

Hi, an example using Python and Elements’s Boudingbox [crop 3D View] import clr import sys import System clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * import Autodesk.DesignScript.Geometry as DS #import Revit API clr.AddReference('RevitAPI') import Autodesk from Autodesk.Revit.DB import * import Autodesk.Revit.DB as DB #import transactionManager and DocumentManager (RevitServices is specific to Dynamo) clr.AddReference('RevitServices') import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager doc = DocumentManager.Instance.CurrentDBDocument def get_Global_Middle(all_bbx): """ # get middle point of global BBX """ minX = min([bbx.Min.X for bbx in all_bbx]) minY = min([bbx.Min.Y for bbx in all_bbx]) minZ = min([bbx.Min.Z for bbx in all_bbx]) # maxX = max([bbx.Max.X for bbx in all_bbx]) maxY = max([bbx.Max.Y for bbx in all_bbx]) maxZ = max([bbx.Max.Z for bbx in all_bbx]) return XYZ((minX + maxX) / 2, (minY + maxY) / 2, (minZ + maxZ) / 2 ) def toList(x): if isinstance(x, list): return x elif hasattr(x, "GetType") and x.GetType().GetInterface("IEnumerable") is not None: return x else : return [x] #Preparing input from dynamo to revit lstElems = toList(UnwrapElement(IN[0])) view = UnwrapElement(IN[1]) margin = 8 lstTfPts = [] lstBBx = [] #Do some action in a Transaction TransactionManager.Instance.EnsureInTransaction(doc) tfView = view.CropBox.Transform.Inverse for elem in lstElems: bbxElemB = elem.get_BoundingBox(view) lstBBx.append(bbxElemB) pt1 = tfView.OfPoint(bbxElemB.Min) pt2 = tfView.OfPoint(bbxElemB.Max) pt3 = tfView.OfPoint(XYZ(bbxElemB.Min.X, bbxElemB.Max.Y, 0)) pt4 = tfView.OfPoint(XYZ(bbxElemB.Max.X, bbxElemB.Min.Y, 0)) lstTfPts.extend([pt1, pt2, pt3, pt4]) # get min max coordinate from transform points minX = min(lstTfPts, key = lambda p : p.X).X minY = min(lstTfPts, key = lambda p : p.Y).Y maxX = max(lstTfPts, key = lambda p : p.X).X maxY = max(lstTfPts, key = lambda p : p.Y).Y # set a new Transform t = Transform.Identity t.Origin = get_Global_Middle(lstBBx) t.BasisX = tfView.BasisX t.BasisY = tfView.BasisY t.BasisZ = tfView.BasisZ # set a new BBX newBox = BoundingBoxXYZ() newBox.Enabled = True newBox.Min = XYZ(minX - margin, minY - margin, -10000) newBox.Max = XYZ(maxX + margin, maxY + margin, -0.10) newBox.Transform = t view.CropBox = newBox TransactionManager.Instance.TransactionTaskDone() OUT = view

Hello and thank you for your reply, I have tested your code and the following error message appears: [image] From what I understood, the Y value of the minimum point is not being retrieved or is a null value. What can be causing this? Also, the updated .dyn file is attached bellow since the script is enormous. I’d upload a print of it but it would lose quality. structureV24.dyn (2.4 MB)

Update: I did some digging up and got to the cause of the issue: I think that the toList function is returning null. Maybe the values in the list I tried to insert weren’t correct (picture bellow) [image] I have tried with all the elements in the active view but it returned the same warning. Any suggestions of what is the issue here? Updated .dyn file: structureV24.dyn (2.4 MB)

Hello again, I implemented your code and ran the script. There was a different error this time but I think it’s related to the same issue as before (picture bellow) [image] Also, in the original post, there’s the .rvt file I’m currently using for testing and the Excel sheets with the reference point coordinates and the material types used for the creation of the structure. The only different file is the .dyn file (which is attached bellow) structureV24.dyn (2.4 MB)

your script does not work well for me, the script generates beams with a very very large distance [image]

That’s strange. What version of Revit are you using? The version I am using is Revit 2020

I think that the code you provided works on Revit 2020 since the script did run. Maybe the issue here lies in the reference points of the beams or in the material family type

Same in Revit 2020 [image] hence my request for your rvt file with the structure made

the error comes because there are no elements in the input IN[0]

try this way
