C# connection to Autocad LT 2014

[Anonymous]

Hi all!

I have a c# connection, this code run fine in Autocad 2014. The final purpose of my program is create a .dwg file and add labels in mentioned .dwg file but not work in Autocad LT 2014 .

My code:

try
{

// Upon creation, attempt to retrieve running instance
m_AcadApp = (AcadApplication)Marshal.GetActiveObject("AutoCAD.Application.19");
m_bAcadInit = true;
}
catch
{
try
{
// Create an instance
m_AcadApp = new AcadApplication();
m_bAcadInit = true;
} catch(Exception ex)
{
MessageBox.Show("An error occurred trying to open the AutoCAD.", "Attention", MessageBoxButtons.OK, MessageBoxIcon.Information);

//In LT version this message appears

}

Is possible open Autocad LT 2014 with my code or similar code?

Thank you very much.

Hi,

you might get start AutoCAD LT using e.g. Process.Start, but at least AutoCAD LT has no built in API, so there is also no COM-interface that can be used like you did with AutoCAD.

That is one of the major reasons why LT is much cheaper than the full version.
