cannot remove the automatically added coincident contraint at the origin

[luiyingchun]

When I draw a line with one of the ends at the origin, an automatic coincident constraint will be created at the origin point but there seems to be NO way to remove it so that the end of the line can be moved. For coincident constraints created at other locations, the symbol of the constraint will show up by hovering the cursor over the point, then the constraints can be removed by selecting and deleting it. The tutorial video shows that the same can be done on the coincident constraint at the origin but I cant do it.  Will appreciate some help

OK , just tried again, the constraint can be removed by right clicking the mouse to bring up the marking menu and select "delete constraint".  There must have been some changes to the software to hide the constraint symbol at the origin.

right click on the line, not the point, near the point, and choose "Delete Coincident"
