[RhinoCommon] AddInstanceObject failed to add history

Easy · June 29, 2022, 2:42am

//RhinoDoc.DocObjects.ObjectTable
public Guid AddInstanceObject(int instanceDefinitionIndex, Transform instanceXform, ObjectAttributes attributes, HistoryRecord history, bool reference)

It seems that the history record cannot be added successfully. Has anyone used it successfully?
Thank you!

How about this?

github.com

mcneel/rhino-developer-samples/blob/7/rhinocommon/cs/SampleCsCommands/SampleCsHistory.cs

using System;
using Rhino;
using Rhino.Commands;

namespace SampleCsCommands
{
  public class SampleCsHistory : Command
  {
    /// <summary>
    /// The only instance of the SampleCsHistory command.
    /// </summary>
    static SampleCsHistory g_command_instance;

    /// <summary>
    /// History recording version.
    /// This field is used to ensure the version of the replay function matches
    /// the version that originally created the geometry.
    /// </summary>
    private const int HISTORY_VERSION = 20131107;

HI @11159
Thank you for your answer!
I have no problem adding history for other types of geometry, but it doesn’t work for blocks.
