Hi, Sorry if this is unrelated, but as seeing this is a post about the beta, here goes. I've installed the Beta 4 and have recently updated to 4 Beta 20 from an earlier version. It opened up fine the first few times, but now it gives me the following message:
Application Error Unable to launch the application. Name: Sweet Home 3D 4.0 Beta Publisher: eTeks From: http://www.sweethome3d.com
Then, there's two buttons: Ok and Details.
If I click details:
Error: Failed to validate signing of launch file. The signed version does not match the downloaded version.
Then there's a tab "Launch File" with a bunch of code and a tab "Exception" with a bunch of info.
I don't know how to fix this. I've tried reinstalling, rebooting, ending the process manually, etc.
If you need either of the texts under those tabs, let me know.

Re: Sweet Home 3D 4.0
Robert, you should click again on the Java Web Start link shown on this page. Depending on your system, Java Web Start applications used to upgrade more easily, but Oracle recently introduced some changes for security sake, that may oblige the user to download the JNLP file each time its content changed. As the JNLP file of the final version is more stable, this issue shouldn't happen at the final release of the version 4.0.

Re: Sweet Home 3D 4.0
Denis, Hans, Szymon, thanks for your feedback. From you answers, this ceiling computation feature doesn't feel perfect, and I agree.
what about an option to exclude a wall from ceiling calculation ? Maybe a checkbox in the wall's properties dialog ?
Nice idea but still too complicate for basic user to understand, as well as the wall's properties dialog is already quite filled with a lot of information. One of my idea was to add a Flat check box in the Ceiling section of the room modification dialog. A more simple option placed among other user interface options relative to ceiling. If the users wonder what it changes, they can test it and undo/redo it, or look in the help. The biggest problem with ceilings is that they are visible only from below, and I'm not sure that playing with that 3D feature was a good idea for people unaware of it.
don't recalculate the ceiling after every change, but make a Recalculate button, just as for the walls around a room.
Sorry but I feel it wouldn't be consistent with the way Sweet Home 3D works for other features: the user sees the effect of its initial drawing or its change at once, and recomputing walls around a room is just a shortcut of something the user could do with existing features. Following your idea, what would happen if the user would move a point of a room? It would keep always the same elevation until he clicks on that button? And if the elevation of some room points is incorrect at the initial creation of a room, recalculating them won't resolve any issue.
I would enable this nice mechanism when there exists only one way of spanning a ceiling (e.g. 2nd from left in top row, or second from top in first column).
Sorry but I'm not sure to understand what you mean.
However, in some complex situations one can do it in more distinct ways. I would disable the mechanism if different strategies of triangulation result in different ceilings.
The triangulation is computed by Java 3D itself. So if I want to test different strategies, I would have to study its algorithm and reprogram it some way, without guaranty that there could be more than one possible strategy at the end!
The mechanism doesn't work fine for low walls.
The Flat option I proposed could help to resolve this issue. But in the case you reported, you should actually create a room for the floor, and a second room for the ceiling with only 4 points at the room corners.

Re: Sweet Home 3D 4.0
Emmanuel,
I fully understand that it's not simple to find a "one size fits all" solution to compute roofs and ceilings. So maybe a two-pronged strategy, which distinguishes between roofs and ceilings, would work better? - Ceilings generally are flat. - Roofs are in a majority of cases non-flat, and/or extend beyond the walls of the building. I have used other 3D programs, and in general they also make this distinction. Even for non-technical users, it wouldn't be too complicated to understand there is a difference between those two parts of a building.
Hans
PS : When using b19, I draw a rectangular room with a partially sloping ceiling (what you call sloping 6 points) it generates one sloping roof, without the bend in it. Is it Ubuntu, or did I forget the magic spell? :-) http://www.mediafire.com/file/wa62c9n9yt5l8py/SlopingCeilingTest#2.sh3d

Re: Sweet Home 3D 4.0
Hans, actually, I wanted to remove the sloping ceiling feature when I introduced levels in version 3.4. But a user warned me that he documented that feature in a book, so we agreed I'll keep it only for last level. Your SlopingCeilingTest#2.sh3d example doesn't work because the room doesn't have six points. Ceiling elevation is computed at room points only.

Re: Sweet Home 3D 4.0
Emmanuel,
Sorry for misunderstanding your improvements. I was living under the impression that one-step-ceilings were introduced for the scenarios you showed.
Would it be possible to slightly improve the "magnetism" for room points, so that it's easier to find the exact spot where room points should connect to wall points? It's easy to find the exact spot for corner points, but not so easy to find the exact spot along a split-up straight wall.
Hans
PS: Making a 6-point room in my example gives a perfect ceiling.

Re: Sweet Home 3D 4.0
is it possible that the last webviewer is not compatible with the lastest BETA ?
I would say no, but since you had a problem that I could reproduce, it must be true. I'll check in the coming days where it could come from.

Re: Sweet Home 3D 4.0
Ok, I fixed the bug. If you want a beta of the viewer, just tell me, I'll send it to you. Thanks for reporting this issue.
