[Plugin] Cloud

thomthom

There are four Cloud threads - can we clean these up please?
For instance;
Removing the download for the old ones,
Replacing [Plugin] with [Obsolete]
Add a link to the new version
Then finally lock the old ones?

When I was looking at the plugin index it was confusing to what was the latest version.

Difficult to keep track of what's new, some topics contain plugins but not the [Plugin] prefix, other topics are posted as questions and then a plugin is added but the first post not renamed with the prefix, etc.

Yea - we should do a cleanup of all these - have them reposted fresh and remove any outdated version.

Thanks very much for providing this plugin, we've recently invested in a Total Station & this translates the point data reliably. Providing a help file is also a boon.
We're also using TIG's contourmaker plugin, which helps when exporting to data to AutoCAD.

Hi,

How to get Cloud_71.rbs and Cloud_6.rb to work?

My intention is to load elevation data of a terrain collected with the help of a GSP-logger to create a terrain model for a village. I noticed that there is a plugin Cloud_71.rbs in the Ruby Library Depot by Didier Bur. I understand that the plugin accepts elevation data, if it is in the CSV-format described in the pdf of the plugin. I downloaded Cloud_71.rbs in the plugin folder of Sketchup 7.1 (Windows XP Pro).

For some reason the Cloud_71.rbs didn't show up in the Plugin menu or any other menu either after restart of Sketchup 7.1. The older "Clouds" with extension .rb show up, but unfortunately I wasn't able to get them work with the downloaded sample files, although I browsed all the possible SketchUcation discussion forums and also some others for help.

Does anyone know if there is an any easy way to get the Cloud_xx.rb plugins to work? And how to get the Cloud_71.rbs plugin show up and make terrain in Sketchup 7.1 or even in the newer Sketchup 8? I'm convinced that there are ways - I just couldn't find the way.

I'd be grateful for your help.

Kind regards Erkki Finni

Hi,
Avoid having more than one version of a plugin installed at the same time, remove older versions of cloud script, this may cause the problem.
Hope this helps,

Hi again,

I removed the oldest versions of the Cloud_xx.rb plugins and
left only Cloud_71.rbs in the Plugin folder of Skecthup 7.1.
I started Skecthup
As it was opened, the File menu included Points Cloud option
After this everything was childsplay - all the test files were
drawn beatifully on the screen. I didn't test the Export-option yet.
I repeated the test with Skecthup 8.0.3117 and the result was also good.

This success made me happy and confident to use the plugin for my orginal purpose; to create terrain by using GPS-logger data as input. So many thanks for your help!

Kind regards Erkki Finni

Sir

anyone tried this on a file with about half a billion points?

Didier Bur

Hi,
It should import the points quite quickly, but for triangulation: forget it (the delaunay algorithm is slow and SU is lazy when drawing such a bunch of new entities).

Hello,
I have tried all of the Cloud_xx plugins into Sketchup 8 and I can't make any of them work. The file I am loading is very very simple. I will paste it below.

I reverted all the way back to the very first Cloud_V6, the earliest that I could find, and the Ruby console says:

which are the coordinates for a landing gear fairing. I have also appended ",0" to the lines in order to have a z-coordinate. I have also used the dialog box to tell the plugin that there is no Z data. Also have selected flattening (or not) in trying to make it work. Have tried every version of plug in from beginning to latest, no luck, will not work in any configuration. In one version of the plugin, it brings up a massive dialog box, so long that I cannot see the bottom, asking me to tell it which elements are which. I can never figure out how to see the bottom of the dialog box (I am amateur Mac user, there must be a way?), but there is no longer a "nothing" option, so I am not sure getting to the bottom would help me.

These are my questions:

Do any of the Cloud plugins work in Sketchup 8?
Is there something wrong with my data, and that is why the Cloud plugin is failing?

I am running Mac OS 10.5.8 on iMac Intel dual core with Sketchup 8.0.3161.

In responding, please keep in mind I don't know anything about Ruby. Thanks for your help.

Update:

I went back to verify that I had, in fact, tried every possible version on Mac. In the process of doing that, I found TIG's fixups, in these two posts:

latest: http://forums.sketchucation.com/viewtopic.php?f=79&t=24733#p240869
slightly earlier fixup: http://forums.sketchucation.com/viewtopic.php?f=79&t=24733#p212737

I can't get either fixup to work in Mac in OS 10.5.8 and Sketchup 8.0.3161 as posted.

I jumped over to WinXP and Sketchup 7.0.10247 using the 'slightly earlier fixup' and was able to load my coordinates (attached PNG).

I saved this over to Mac and can keep working now, however, I would really like to be able to work only on the Mac.

I studied TIG's posts a bit and it seemed like the problem was some statements in the script that 1) were not portable from Win to Mac, and 2) were possibly non-standard usage of Sketchup API that might break the script in future versions. However, I also noticed some strange behavior on Mac that leads me to believe there is something wrong in the file handling of some sort.

When used on Mac with the file as shown, I get this error:

"More than 3 XYZ coordinates per line (139).
Please select X, Y, and Z in the following line sample."

When I look at the line sample in the dialog box, it appears to show three coordinates, i.e., "1.000000,-0.003780,0" (note that I went back and added the extra ",0" just in case that was a problem - it wasn't). However, I can use the arrow keys and it turns out that a much larger part of the file is in the text box that shows the line sample. I can use the arrows to scroll around inside the tiny text box and see many other coordinates. I didn't think to see if the whole file were in that text box, but I did delete everything after the first line - but the same problem happens, the script simply will not process any data. I then get the same error as in my post above.

I have become convinced that the problem has something to do with how files are represented on the Mac versus Win. Is it possibly to do with CR/LF problems? Or something else wrong with my file?

Otherwise, I have found it extremely difficult to get any XYZ data into Sketchup, and not possible at all on the Mac (for me so far). It is very difficult to find the latest versions (I search for well over an hour to find TIG's fixups), to understand which ones have bugs and which ones not, etc etc. Even in the Plugin index there are four versions of Cloud_V6 referenced.

I am not able to sort out whether I have the wrong plugin or whether I am doing something wrong. Help is greatly appreciated, I have done everything I know how to do. Thanks.

The links you gave refer to some tweaks I did to v6~.
This thread starts with v71.zip.
Have you downloaded that ??
That was fixed after I spotted a mistake in Didier Bur's coding of v70...
It works fine for me and other users on PC/MAC.
It's under Menu > File > Points Cloud > Import.
BUT the file MUST have 3 or more values per line separated by the specified character - e.g. ','
If you only have two it will return an error.
To add trailing zeros [,0] to the file you need to do some processing in a plain-text editor.
Do NOT use a word-processor - that will add hidden characters in the text and mess up big time.
Not sure what the MAC equivalent app' to Notepad++.exe is, but you need to ensure proper carriage-returns on line ends too - is there an option in the MAC text-editor for this ?
To edit the file in Ruby this one liner should do it - paste into the Ruby Console...


filei="path_to_file/mypoints2.csv";filei="path_to_file/mypoints3.csv";;file=File.new(fileo, "w");IO.readlines(filei).each{|t|next if t=="\n";file.puts(t.gsub("\n",",0\n"));};file.close;

edit it to replace path_to_file with the actual path to the folder containing the csv
the ..3.csv version has ,0 appended to each line...

TIG,
Thanks very much for your reply. I had previously tried the v71 zip file. At your suggestion, I re-downloaded it anew, placed into my plugins folder, and accessed it from the file menu as you indicated. I also used TextEdit on the Mac to edit the file to have three values per line as you indicate. TextEdit on the Mac usually edits in Rich Text Format (RTF); however, there is an option to switch to Plain Text, which I did before editing. I tried two versions of the file. In one version I had values separated by commas (and used the dialog to tell the script that). In another version, I separated values with semicolons as shown in all of the examples in the v71 folder. Both gave the exact same failure, see screenshot below.

I have also tried saving the CSV file directly from Excel on the Mac. And also from Word on the Mac, where I had Word display only plain text. I also opened the file using two different programming editors on the Mac, NetBeans and Xcode. Both have 'plain text' editors that I use to write software. It doesn't matter what text editor I save the file from, it simply will not work. No matter what I do. I am an aerospace engineer and know my way around a computer, though I am only an amateur programming. Believe me when I say, I would not come to you unless I had exhausted every possible option that I could possibly find or conceive of. No joy. The one thing I have not done is use the Ruby statements you show below. I have no experience with Ruby and don't know how to do that yet, but I will go figure it out next.

In any case, attached are 1) the exact file I am trying to pull in using (now) Cloud v7.1 and 2) the screenshot of the result. This screen shot is taken as follows. I activate the Cloud plugin using File menu item. It brings up a dialog box to select the file, which I do. Then it brings up the dialog box asking for the delimiter. The last line of that dialog box (fourth line) shows the 'line example', and it is highlighted all in blue. I can scroll inside there using the arrow keys, and it appears there is a massive amount of data in there. Clearly, something is not reading the values correctly from the file, as if the program does not know where the end of the line is. When I hit return, I get the screenshot below: a dialog box asking me to pick the meaning for a long list of values. However, the dialog is off the bottom of the screen. I have discovered no way to view the bottom ('amateur Mac user'). I go ahead and hit return anyway, and script loads one point into the Sketchup drawing space. No other points are loaded. (By the way, earlier versions of the script had the option for 'Nothing' in the pick list for the attribute meanings - no longer an option for some reason, although, it currently doesn't matter as I can't see the bottom of the dialog.)

Others have had problems getting the Cloud plugins to work correctly. I have absolutely scoured their threads trying to find out what, exactly, they did to solve their problem and what, exactly, I am doing wrong. If the answer I need is in fact in those threads, I am completely missing it, if you or someone else could point out to me precisely my mistake I would be grateful.

I'm going to try three more things: a) type the file in by hand from scratch one more time into a guaranteed plain-text editor on Mac (probably Xcode) b) type the file in by hand from scratch on WinXP and move the file over to Mac before loading c) delete out the last [,0] on each line and process that [x,y] version with your Ruby script, which appears to look for '\n' explicitly. If you have any ideas at all please let me know, I am willing to try anything at this point (other than relenting to always loading skp files in WinXP and moving them over to Mac then copying into main drawing... ugh).

I'm out of ideas. Please advise. Thank you for your help.

I think it's something to do with the way your file has carriage-returns at the ends of lines etc ???
Can you post the actual file you have the big problem with... I'll look at it and re-post a 'fixed' version to see if it's any better...
Then we might be one step nearer a solution...

aerostreak

TIG,
Thanks for quick reply. I found the problem, you were exactly right, problem was with Mac linefeeds. I posted the original file above, the link to it is dwarfed by the screenshot.

I found the solution in Xcode. There is an editor option to convert the linefeeds on any file between Unix (LF), Mac (CR), and Win (CF/LF). Saving the file with either Unix or Win worked great - Cloud script worked in Sketchup exactly as advertised. Saving the file with Mac (CR) - failure.

Here is the screenshot of the fix, once I found the menu option I had the whole file loaded into Sketchup in less than 60 seconds.

Man alive, this trivial problem cost me probably six hours in total and about a week off the end of my life...

Thanks for your patience, I appreciate the help.

p.s. Seems like it might be worthwhile to mod the script to automatically fix this (i.e., to properly handle the Mac CR-only default), or, to provide a separate plugin that can pre-process input files for people before they try to load data with other plugins...

TIG

Hoo-bloody-ray!
Didier - you listening ?
I thought that Ruby's '\n' took any version of carriage-return appropriately ???
Weird.............
At least we have a 'fix'...

Didier Bur

Seems that CR in Ruby is "\r" while CRLF is "\n".
I've tweaked the script to check if lines end with CRLF or CR, and here's what I got from the file:

See new release at top of this thread.
