Can't create Sweep from FamilySymbolProfile.

Hello All!

I try to create sweep with next code:

'Get FamilySymbolProfile Dim fsp As FamilySymbolProfile = GetSweepProfileFamily(doc, currentRetailingWallType.Profiles(0).Name) 'Get family Metric Generic Model path Dim famTemplatePath As String = commandData.Application.Application.FamilyTemplatePath famTemplatePath = famTemplatePath.Substring(0, famTemplatePath.LastIndexOf("\")) + "\Family Templates\English" Dim pat As String = Path.Combine(famTemplatePath, "Metric Generic Model.rft") 'Get family document Metric Generic Model Dim fdoc As Document = commandData.Application.Application.NewFamilyDocument(pat) Dim sweep As Sweep = Nothing Dim fTr As New Transaction(fdoc, "CreateSweep") fTr.Start() Dim plane As Plane = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, New XYZ(0, 0, 0)) Dim sketchplane1 As SketchPlane = SketchPlane.Create(fdoc, plane) Dim pnt4 As New XYZ(10, 0, 0) Dim pnt5 As New XYZ(0, 10, 0) Dim curve As Curve = Line.CreateBound(pnt4, pnt5) Dim curves As New CurveArray() curves.Append(curve) ' create a solid sweep sweep = fdoc.FamilyCreate.NewSweep(True, curves, sketchplane1, fsp, 0, ProfilePlaneLocation.Start) fTr.Commit()

But I get error: "Autodesk.Revit.Exceptions.ArgumentException: "One of the conditions for the inputs was not satisfied. Consult the documentation for requirements for each argument."

Anybody help me?

Before you create the sweep programmatically, generate the model curves that you plan to use and perform the sweep generation manually in the end user interface. That will give you more precise information on any problems encountered:

You find the profile in a document (doc) and try to use it in another document (fdoc). That will not work. Copy the profile-family to the fdoc.

I figure it.

Instead of using:

sweep = fdoc.FamilyCreate.NewSweep (True, curves, sketchplane1, fsp, 0, ProfilePlaneLocation.Start)

where fsp is FamilySymbolProfile,

I get profile geometry from a family document to a swp variable:

Dim ffilter As ElementClassFilter = New ElementClassFilter (GetType (CurveElement)) Dim fcollector As FilteredElementCollector = New FilteredElementCollector (fdoc) fcollector.WherePasses (ffilter) Dim curves As List (Of DetailCurve) = fcollector.Cast (Of DetailCurve) .ToList Dim caa As New CurveArrArray Dim ca As New CurveArray For Each c As Detail Curve In curves ca.Append (c.GeometryCurve) Next caa.append (ca) Dim swp As SweepProfile = doc.Application.Create.NewCurveLoopsProfile (caa)

and call:

sweep = fdoc.FamilyCreate.NewSweep (True, curves, sketchplane1, swp, 0, ProfilePlaneLocation.Start)

Thanks for posting your solution Andrew. All the examples I found for creating sweeps use a newly generated profile. All very well for simple examples, but not useful if you have an existing complex profile. Very much appreciated. Dale

PS here is my C# conversion:

public static SweepProfile CreateSweepProfileFromProfile(RvtDoc pDoc) { ElementClassFilter ffilter = new ElementClassFilter(typeof(CurveElement)); FilteredElementCollector fcollector = new FilteredElementCollector(pDoc); fcollector.WherePasses(ffilter); List<DetailCurve> curves = fcollector.Cast<DetailCurve>().ToList(); CurveArrArray caa = new CurveArrArray(); CurveArray ca = new CurveArray(); foreach (DetailCurve c in curves) ca.Append(c.GeometryCurve); caa.Append(ca); SweepProfile swp = pDoc.Application.Create.NewCurveLoopsProfile(caa); // usage // sweep = fdoc.FamilyCreate.NewSweep(true, curves, sketchplane1, swp, 0, ProfilePlaneLocation.Start); return swp; }

I've looked at your two answers several times over now and am still very confused by them.

The sweep creation requires a sweep path and a sweep profile.

The path is the second input argument, the profile the fourth.

You pass in `curves` as the second and `swp` as the fourth.

However, you also use `curves` to generate `swp`.

Isn't that awfully weird? Why are you using the sweep profile to define the sweep path, and vice versa?

Should not the path and the profile be two completely separate things?

Sorry if I am misunderstanding something completely...

Thank you for any clarification!

Here is an example from The Building Coder samples that I understand better, by the way:

Taking another look at this, I not that this issue (or very similar ones) have been discussed repeatedly here in the past and the results summarised by The Building Coder, in case that is of any use:
