LeaderToMleader will 'convert' old style Leaders and Qleaders and their text into modern Mleader objects.

Simply run the routine, pick the old Leader, then pick the old text associated with that Leader.

Leader to Mleader will delete the old Leader and text and place the new Mleader of your current Mleader style and size into the drawing where the old Leader and text was.

It will be on the same layer as the old Leader. Note, if original Leader contains multiple lines of text and it is not Mtext, you will need to first use AutoCAD's txt2mtxt routine (found in the Express tools) to convert the lines of text to one Mtext object.

The installer that ran when you downloaded this app/plug-in from the Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. You may need to restart the Autodesk product to activate the app/plug-in. To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 8.1/10/11) and uninstall as you would any other application from your system.

Only works on existing multiline Mtext or single line text. If original Leader contains multiple lines of text and it is not Mtext, you will need to first use AutoCAD's txt2mtxt routine (found in the Express tools) to convert the lines of text to one Mtext object.

Also, your current Mleader style must be set to limit leader points to 2. See your MLEADER STYLE > Modify > Leader Structure > Maximum leader points = 2.  If your current leader has multiple vertices, extra vertices can be added to the new Mleader by clicking on the new Mleader and hovering over the arrow grip, select Add Vertex.
