I need to mark out chainage along an alignment line. The final result should looks like picture. After all chainage annotation is done, i need to export the line and annotation to IFC and view them in Revit. However all lines and annotation disappear after exporting the file to revit.
MY current annotation shown in picture is simply a text with rotation. I doubt if my method is correct.
Anyone know how to create proper 3D annotation and lne that can be exported to IFC then revit?
Which version of OpenBuildings Designer are you using? Also, which MVD are you using while exporting to IFC?
IFC export from OpenBuildings Designer will export geometry, its fundamental geometric properties and it's attached DataGroup properties.
Text annotation will not be exported.
DWG may be a better route to get these elements into Revit, depending on what you need to exchange with the Revit users.
buildingSMART are working on expanding IFC to add definitions for linear infrastructure specific elements such as alignments which we will adopt once they are available.
Open Building Designer Update 6
what is MVD?
i have found a way to do it by extruding the text element, when text becomes an extrusion surface it can be exported by IFC and view in Revit.
However i faced another problem where my 2D text file is a mixture of text element and text node element. I can extrude only the text element. Is there any way to convert all text node to text element so that i can extrude the files ? Thank you!
