How to Set Line Pattern in Line Style

[Anonymous]

I'm creating new line styles in Revit MEP 2013 through the API in VB.Net, and I've almost got everything figured out... except setting the line pattern. There doesn't seem to be a way to do this one, last step. Any ideas?

Here's what I have so far:

PublicFunction LoadStyle(ByVal n AsInteger) AsBoolean

Dim lineCat As Categories = m_RvtDoc.Settings.Categories

ForEach objCategory As Category In lineCat

If objCategory.Name = "Lines"Then

If objCategory.CanAddSubcategory = TrueThen

Try

Dim cat As Category = lineCat.NewSubcategory(objCategory, MEP(n, 6))

'set color

If MEP(n, 7) <> ""Then

Dim r, g, b AsInteger

                            r = MEP(n, 7)

                            g = MEP(n, 8)

                            b = MEP(n, 9)

Dim c As Autodesk.Revit.DB.Color = New Autodesk.Revit.DB.Color(r, g, b)

                            cat.LineColor = c

EndIf

'set lineweight

If MEP(n, 11) <> ""Then

                            cat.SetLineWeight(

CInt(MEP(n, 11)), GraphicsStyleType.Projection)

EndIf

'set line pattern

If MEP(n, 10) <> ""Then

'cat.LinePatternId = GetElementByName(GetType(LinePatternElement), MEP(n, 10))

EndIf

Catch

                        MsgBox(

"Line style " & MEP(n, 6) & " already exists.", MsgBoxStyle.Information, "Load Systems Error")

EndTry

Exit For

Else

                    MsgBox(

"Can't add line style.")

Exit For

EndIf

EndIf

Next

　

EndFunction

Revit didn't expose the API to change category's line pattern. Revit engineering team already knew this request. Hope this will come not long.

Thanks for the response, Joe. Would it be possible to check to see if it's exposed in Revit 2014? And are there any workarounds? This is very important for my project.

Thanks,

Thanks for your comments on the API wish. I passed on your comments on this request to the engineering team.

+1 to adding this feature!

+1 Please add this feature

[boostyourbim]

Yes, please fill this gap Autodesk so we can set the line style's line pattern via the API

Dear All,

I have added your comments to the Epic story, there is still plans to work on this, but still needs to be prioritzed agains all other requests. 

Thank you very much for all your patience and collaboration. 

Cheers,

Yes, please add this! Has it been done yet? How many more years?

Hey,

in Revit 2017 API, there is a new Category.SetLinePatternId method.

Seems that Autodesk provides a solution, finally.

but SetLinePatternId() doesn't work, SetLineWeight() works fine along w/ LineColor

subCat.SetLineWeight((int)cat.GetLineWeight(GraphicsStyleType.Projection), GraphicsStyleType.Projection); // works OK
subCat.LineColor = cat.LineColor; // works OK
subCat.SetLinePatternId(cat.GetLinePatternId(GraphicsStyleType.Projection), GraphicsStyleType.Projection); // doesn't work
