This quick tutorial shows how to create a macro button on a toolbar. This illustrates a quick way to Unload/Reload Grasshopper for development purposes. I use it in the course Developing Your Own Grasshopper Plugin. I also show a quick python script that I apply to a button as well. The python script is a simple mitre tool, nothing fancy. The code for both of these are below.

#Cap Planar holes in each mitred object and MergeAllFaces
for brep in newMitredPieces:
    rs.SelectObject(brep)
    rs.CapPlanarHoles(brep)
    rs.Command("_MergeAllFaces")
    rs.UnselectAllObjects()
 
#Add objects to be deleted to the removeObjects List
removeObjects = [cutPlane] 
 
#Delete the objects
rs.DeleteObjects(removeObjects)
