Summary	0004467: Cloning and placing to automatically constrain to old objects creates malformed constraints
Description	Referencing this thread. Creating a circle and connected line and then cloning these and placing the clone to automatically constrain to original objects generates a malformed constraint. I have reproduced this as far beck as 0.19.21125 which is the earliest 0.19 I have. I cannot reproduce this on 0.18.4, possibly because the automatic constrain on clone placement doesn't work.
Steps To Reproduce	1. Start FreeCAD. 2. Open the report view panel at the bottom of the screen. 3. Create a new document. 4. Go to the Part Design WB. 5. Create a body. 6. Create a sketch on the XY plane. 7. Place a circle, not constrained in location and constrain the radius to 2.5mm. 8. Place a line with one end constrained to the center of the circle and the other end to the right. Add a horizontal constraint and a length constraint of 14mm. 9. Select both objects and then slowly double-click the center of the circle so that everything is still selected and the circle center is last selected. 10. Clone the objects and use the mouse to move the clone reference point onto the right end of the line so that the constrained constraint symbol (a circle on a diagonal cross) shows to make the cloned circle constrained to the old line and click the mouse button. 11. These errors will immediately appear in the report window: 12:03:06 Sketcher constraint number 8 is malformed! 12:03:06 Sketch Sketch has malformed constraints! 12:03:06 Sketcher constraint number 8 is malformed! 12:03:06 Sketcher constraint number 8 is malformed! 12:03:06 Sketch Sketch has malformed constraints! In 0.18.4, step 10 above still shows the constrained constraint symbol (just a dot in that release) but the cloned line and original circle does not constrain.
Additional Information	The attached file is the result of the above procedure.

TedM 2020-10-18 20:49 reporter ~0014910	So, small error in procedure. Step 10 should read: 10. Clone the objects and use the mouse to move the clone reference point onto the right end of the line so that the constrained constraint symbol (a circle on a diagonal cross) shows to make the cloned circle constrained to the old line and ~~release~~ click the mouse button.
