Curve array problems in blender

The current scale of the 'tower detail' object is 0.932, that's why it doesn't complete the circle all the way. Hit CTRL+A with the object selected and hit "Scale". This applies the current scale of the object and sets it 1.

Hi romainhd,  as numbernine said the scale should be applied, but it looks like you did that already in the last screenshot ( and you also said that you applied it), but for the spiralling, that has to do with the rotation of your detail segment. Set the Z-rotation back to 0. (Do NOT apply the rotation, but set it to 0 in the N-panel!)

spikeyxxx hi, thanks but it didnt change. Here s a quick video: https://www.youtube.com/watch?v=oiNdDXpAgno&feature=youtu.be

rromainhd Bummer! Could you share your .blend? That would be extremely helpful! Otherwise it's just a guessing game;)

I've had similar problems with the curve modifier and there is a lot that you could be doing wrong.

The video showed the problem all right, but not what's causing it. At least, I couldn't figure it out, just by looking at it.

I'm convinced that I could help you if I had access to your .blend.

spikeyxxx how can I share the blend file here?

rromainhd I  don't know if there is any other way to do this, but you can upload it to a cloud service like, for instance, 'Dropbox' and then share the link.

spikeyxxx https://www.dropbox.com/home/Public?preview=ViandenPlangrPalaisneiblend.blend1

rromainhd Sorry, but the link just gets me into Dropbox, it doesn't give me access to your .blend...

spikeyxxx https://www.dropbox.com/s/opbxh0xv8d91jl3/ViandenPlangrPalaisneiblend.blend1?dl=0

rromainhd Yes, it's working, but this is your .blend1, I need the .blend, because I can't open the . blend1. Sorry for all the inconvenience, but we will get there in the end:D

spikeyxxx whats the difference? ;) here the link, thank you spike!

rromainhd Okay, I've got it now, I'll look into it. As for the difference, as far as I understand it, the .blend1 is sort of a backup. There is an Article about this, just released, by Wayne: https://cgcookie.com/articles/what-is-a-blend1-file-and-do-you-really-need-them

rromainhd So it seems to be simply a matter of the rotation of the 'Turmarray' as I suspected, Maybe this will show you how the rotation affects the result: https://youtu.be/Gq9eqqdphLc

It's really poor quality, but I hope you can see it, because YT told me the video is private, although I set it to public???

spikeyxxx Thank you, yes it worked :) Maybe you can help me with the next Problem, I want to do one Roof with the Building and the Towers, how should i do it? I tried to extrude the edges of a clyinder, but the Transition from it between the Roof of Tower and Building is a mess ;) thank you

rromainhd I am not quite sure what you mean. Do you want to achieve something like in the pictures? If so, what does your 'mess' look like? A screenshot would be helpful...

spikeyxxx I am modeling the whole Building, but the Roof is the hardest part because the Tower Roofs are connected to the main Building, i tried to extrude from a cone but that wont work properly. 

rromainhd I'll look into it tomorrow. But did you consider using booleans and then retopologize?

rromainhd You're close, but I would suggest making a 'mold' where you simply intersect the towers in the wall/roof.

Then you can Duplicate the tower, P > Separate by Selection, turn on Face snapping and manipulate vertices into place.

Something like this maybe:

spikeyxxx how do you intersect that and connect?

rromainhd Simply put them 'through' each other. You can join them, make them one object, by selecting them in Object Mode and press CTRL + J, although that ain't even necessary, it  just makes it more organized and easier to temporarily hide the 'mould' ( I misspelled that earlier...).
