1.Set the reference of the control
2.Using axpview to open the .ed or .pvz drawing
Action<string> actionDelegate = x => { this.axpview1.sourceUrl = x; };
OpenFileDialog openFileDialog = new OpenFileDialog()
{
InitialDirectory = @"D:\2023\parts\",
Filter = @"Creo Viewer Files(*.pvz)|*.pvz|All files(*.*)|*.*"
};
DialogResult result1 = openFileDialog.ShowDialog();
if (result1 == DialogResult.OK && !string.IsNullOrWhiteSpace(openFileDialog.FileName))
{
path = openFileDialog.FileName;
}
Task.Run(() =>
{
axpview1.BeginInvoke(actionDelegate, path);
});3.set the bg color for the axpview
int hexValue = (129 << 16) | (156 << 😎 | 243;
//rgb(129,156,243) to hex color
string hexColorCode = $"0x{hexValue:X6}";
axpview1.backgroundcolor = hexColorCode;4.Get the view location and then set all the default views location
//1.If you wanna to get the view location should coding like that
string str = axpview1.GetViewLocation();
//2.The result is like that "-0.993508 -0.0579201 0.0979185 0 0.0025464 //0.849163 0.528125 0 -0.113737 0.524945 -0.843502 0 2.36994 29.8653 -27.6611 1"
//got is, this string is build by the 4x4 matrix
//3.Actually you can set the view location via the matrix you get
axpview1.SetViewLocation("-0.993508 -0.0579201 0.0979185 0 0.0025464 0.849163 0.528125 0 -0.113737 0.524945 -0.843502 0 2.36994 29.8653 -27.6611 1");
//you can get all the default views' location and set the new location by code 5.But what if you want to rotating,moving,scaling the view?
5.1 Rotating matrixs
//firstly, you should know some basic knowledges about the matrix operation
//you can get the formal rotating matrix like the below codes in internet
/// <summary>
/// X轴旋转基准矩阵
/// </summary>

/// <returns></returns>

0, Math.Cos(ang).ToFloat(), -Math.Sin(ang).ToFloat(), 0,
0, Math.Sin(ang).ToFloat(), Math.Cos(ang).ToFloat(), 0,
0, 0, 0, 1

0, 0, 1, 0,
0, 0, 0, 1
);
return matrix4X4;
}5.2 For example , we want rotate the view around the axis "Y" with degree 180
//1.you should transform the angle from degree to radian
double angy = 180 * (Math.PI / 180);
//2.The the rotating matrix for axis Y(in step 5.1)
Matrix4x4 yMatrix = GetYRotateMatrix((float)angy);
//3.Then get the original view location matrix string, then transform it to 4X4 matrix
string oriMatrix2 = axpview1.GetViewLocation();
var list2 = oriMatrix2.Split(" ".ToCharArray());
Matrix4x4 matrix4X4v2 = ListToMatrix(list2);
//4.Then you got the new view matrxi by these two matrix
Matrix4x4 destMatrixv2 = Matrix4x4.Multiply(matrix4X4v2, yMatrix);
//5.Transform the new matrix to the matrix string the axpview need
string strv2 = MatrixToString(destMatrixv2);
//6.Set new view location and Refresh
axpview1.SetViewLocation(strv2);
axpview1.Refresh();5.2 Moving operation

break;
}

string str = MatrixToString(destMatrix);
axpview1.SetViewLocation(str);
axpview1.Refresh();
}5.3 Moving operation matrix

}5.4 Scaling operation

{
//actually the scale elements should be scale.toFloat(),however,in this control should be reciprocal

0, 1 / scale.ToFloat(), 0, 0,

Finally, all those codes should be add the checking logic for the user input params by youself
