When I try to read an IFC-file (pipe example) I get an error when parsing a PropertySingleValue:

"Die Länge darf nicht kleiner als 0 (null) sein.\r\nParametername: length"} | System.ArgumentOutOfRangeException

It is the "DN" value of the pipe ("400.0000") that is not working.

There seem to be two ways to create new guids, either by ifc.GloballyUniqueId() or ifc.GloballyUniqueId.NewId() (the latter being referenced here: https://github.com/IfcSharp/IfcSharpApps/blob/d1e8bb11abc9e39638b9766661443471e568eb58/IfcSharp/hello_project/hello_project.cs).
Neither is working for me. Anything I miss?

Would it be possible to specify which license is available for this project? LGPL? MIT? BSD? etc.

Love this project!

The license information would allow us to know that it is an open source project, and know how we can use it in other projects. Your project is listed on this page: https://wiki.osarch.org/index.php?title=AEC_Free_Software_directory#Software_Development

#186= IFCTRIMMEDCURVE(#185,(IFCPARAMETERVALUE(269.874418757191)), IFCPARAMETERVALUE(285.07364578635)),.T.,.PARAMETER.);

This is a snippet of an IFC file which causes this error below.

ERROR on Parse2LIST.2:#186= IFCTRIMMEDCURVE(#185,(IFCPARAMETERVALUE(269.874418757191)),(IFCPARAMETERVALUE(285.07364578635)),.T.,.PARAMETER.);

I'm trying some basic operations with this library, however, I get a few errors. I want to convert an IFC4-File to Sqlite using the following code lines:

Model CurrentModel = ifc.Model.FromStepFile("PATH_TO_FILE\\file.ifc");

CurrentModel.ToSqliteFile();

I receive the following errors (console)
TODO List++TYPE: Base=ListElement_List2to2_LengthMeasure not supportet in
followed by an IfcCartesianPointList2D. Is this not yet implemented or do I miss something here?

In Visual Studio I also get the following error:
$exception | {"Der Konstruktor für den Typ "ifc.Value" wurde nicht gefunden."} | System.MissingMethodException

Hi Bernhard,

how do you generate a schema for IFC2X3, at moment it only seems to work for IFC4X2. I can see you can include / exclude schema, but not sure how it generates different ones?

Thank you

I'm considering porting some of the work here to C++ and Python so that you can more easily cross platform import/export SQL and SQLite. Porting creates the risk of being out of sync with your repository. What are the plans in keeping the schema more or less stable, and how does this fit into the work of buildingSMART?

how can I reenable the Sqlite output? or is it just temporarily removed in the delepment branch?

I tried to import different IFC-files; however I get some errors. Code looks like this:

ifc.Model helloProject = ifc.Model.FromStepFile("C:\\Users\\abc\\Documents\\AC20-FZK-Haus.ifc");

"Der Typ "Ifc.FacetedBrep " in der Assembly "IfcSharpLibrary, Version=0.0.0.1, Culture=neutral, PublicKeyToken=null" konnte nicht geladen werden."

For other files I get a similar message concerning "Ifc.Value". (I used the "FZK house" model from https://www.ifcwiki.org/index.php?title=KIT_IFC_Examples)

After some attempts of writing IFC models to the sql server an entity is created twice (#3909 for me). Maybe a transaction problem? It happens for not successful write to database.

Hi Friedrich, I made a small .exp test to map from IFC schema/spec to SQLite

test.zip

The requirements:

1. Each TYPE and ENTITY type should be a table - without duplication (I don't care about inverses/relationships, so there's not a need to map relationships, just TYPES and ENTITY types as individual tables without mapping parent/child) - also I want to drop Ifc prefixes (IfcPerson = Person)
2. A query that shows each ENTITY holds which ENTITY types (including inverses) but it won't be a table, it'd be just a list or something like that

Is there a guide for getting this set up on MySQL?

done

Hi team, can I know the reason why this source missing, your team still working on process ?
I saw so many log can't resolve

Thank you
