Closed perimeter for hatchings ?

Lamy
Hello,
I am facing a problem to use the hatchings function.
When validating my hatching a message allways says the the selected perimeter is not closed.
My question is : can construction lines, comming from another layer, be the reason ?
(2 construction lines are crossing my selected perimeter ...)

NB : thanks to forget my bad english !

Hi Lamy

If you make the Construction layer invisible, your closed contour for hatching should work.

Here you have : I tried another time ... impossible...
I have to fill the main roof (at all the very top of the house only, on both side of course : only one contour) as I did it for the small door-roof, as you can see...

I cleaned up your roof during by removing gaps between entities of the contour:

1, Modify->Move to move one entity (let's call it entity A, from now on) of the contour by offset 100,0
2, check "Snap to endpoints" only in the "Snap toolbar"
3, select a neighbour of the moved entity A in step 1 by selecting the connection point of this neighbour as reference point, and the the connection point of entity A as the target point; select "Delete existing" to continue;
4, repeat step 3 for all entities left in the contour by the contour order
5, After the last entity moved to new position, use Modify->"trim two" to close the potential gap to entity A;
6, move the contour back by offset -100,0

Wonderfull !
Great !!
I prefered to re-do your steps because I prefered to do it myself, and because I worked 2 hours after giving you and did not want to loose my work.
(And I prefer explanation than to let doing my work by others ...)

But I still have a question : how appened suh a problem ?
I drawed my roof line by line, triming each one on the other ...(with "trim one")

Many thanks to you !

I noticed you have two extra lines lie under the contour. Those two lines are not not connected, and could be selected during hatching, leaving a broken contour.

Moving the contour by an offset exposes this problem.

Glad you got it sorted out, seems I have a shadow who beat me to the answer.
