Hi everyone! maybe you can answer wats the problem: i've got lines from Microstation and i want to make polygons, I've used AreaBuilder, but it doesn't aggregate them. what' the issue? how i can do it, or how i can change lines?

This is because the lines are not closed. I got it working by adding a Snapper transformer before the AreaBuilder, distance 0.1.

2021-02-03_09h32_11The coordinates of the not snapped line under / left are

4193999.855610099, 7495471.387215009

4193999.855610528, 7495471.387214141

which are different.

oh! thank you! i had such idea, but i can't change geometry - in other buildings, because of snapping i am starting to get false polygons. i thought it is something wrong in lines, but coordinates of end points are identical. it bugs me, that i can make polygons in Microstation without extra snapping, using standart tools.

I have absolutely no Microstation experience but I think the software fixes this for you under the hood. FME works with the real data, which is not always easier.

thank you!) i am also not a professional in Microstation and will read more about their algorithms, and i completely agree with you when you talk about complexity of processing pure data
