good day - i ve managed to combine dots in the canvas - see how i did it

but if i want to get the results - and configure the path ect etx - by jupressing the "enter-"button i get the result that are not (!) wanted. see below

hello dear friends - i tried out another option - see the image below..

see thie image below - well i guess that this pathway of do the steps could be right - in other words - the "right"one.

the path has a fill color at the beginning - this is not necesary - i need to choose a so called "fill-tab" and then use the red big X - and choose  no color.. at all

Looks like progress.

No need for shape on the pen tool. 

Snap to object centers will help.
