Loading multiple stl

[atrev]

What is the best way to load in multiple STL files into the same control?

The only way I can seem to do this is to load the STL into a separate control, and then copy the sections loaded in the object array of the main control?
I don't really want the seperate control on the form if I can help it.

Is there a neater way to do this?

Thanks

Hello
You do not need another control.

It is done by creating new model in memory, getting its IModelEx and using IModelEx.Load() like in Samples\NET\C#\3DBugger\DebuggerForm.cs :
IModel iModel = (IModel)m_iDIObjGenerator.Create(EObjectType.eObjTypeModelGenerator);
IModelEx iModelEx = (IModelEx)iModel;
iModelEx.Load(strPath);
.. copy objects into the main model
The format is detected by the extension of strPath. It can be stl, glm, etc

The DataFlow example demonstrates this. It has File>Add Objects menu option. C# version in Samples\NET\C#\DataFlow\DataFlowForm.cs OnImportObjects() uses a tiny library to show using sharing code with KC. It is not relevant here. You can just copy code from Samples\NET\C#\KernCADLib\ModelManager.cs ImportObjects()

If you need numerous stl load operations it is better to convert them all in a loop as background operation to .glm. Stl load with all the analysis checks is slow for large files

using this code for load, accessing the stl context to turn off the dialog when opening but it doesn't seem to stop it happening

Code: Select all

 Dim allObjects As IArray = CType(AxKernCADnet1.GetModel, IArray)
For i As Integer = 0 To ofd.FileNames.Length - 1
    If File.Exists(ofd.FileNames(i)) Then
        Dim m_iDIObjGenerator As IDIObjGenerator = CType(AxKernCADnet1.GetView, IDIObjGenerator)


        Dim mdl As IModelEx = CType(m_iDIObjGenerator.Create(EObjectType.eObjTypeModelGenerator), IModelEx)


        Dim options As KernCADnet.ISTLDataContext = CType(mdl, ISTLDataContext)
        options.SetVerbose(False)
        options.SetNoWarnings(True)
        options.SetSeparateObjects(False)


        mdl.LoadEx(ofd.FileNames(i), options)
        Dim mdl2 As IModel = CType(mdl, IModel)

        For j As Integer = 0 To mdl2.GetSectionCount - 1
            allObjects.Add(mdl2.GetSection(j))
        Next


    End If
Next

We have fixed this one in update 3752: http://www.dynoinsight.com/ProDown.htm
BTW this is a different issue. It should be another thread on bugs forum
