Text , X , Y , Z import

Hi
I cant get it to work properly , I only get this error message from the ruby console, And I get some errors when starting up SketchUp

cptstxt
Error: #<NameError: (eval):894: undefined local variable or method `cptstxt' for main:Object>
(eval):894

Your script says " require 'sketchup.rb' "
Does that mean that I have to copy/paste the file from the "tools" folder and into the "plugin" folder?

Regards
Kristoffer

Hi , I managed to fix it
It was just missing the "#" on the 3 first lines

The plugin works perfect Thank you so mutch for your help .

Best regards'

You need to 'select all' and copy/paste it - you must have missed something off ?
The =begin...=end is the same as putting # at the start of each line - these are 'comments', not read by the Ruby interpreter. As there's only one line of 'comments' I could have omitted the =begin and =end lines completely and put a # at the start of the line of instructions - it'd been simpler! I just made the script from my own template that already has that format in it as multiple lines of comments/notes are often needed...
Do not move sketchup.rb from the Tools folder. It loads automatically from there.
It is good practice to add the line require 'sketchup.rb' at the start - most scripts need Sketchup's functions to run and will report an error if they load before it does; the ' require' waits for the specified file to load first... It's an instruction to the Ruby interpreter, not you !
Glad it's working - did you notice that you can adjust the location of the text and leader length by playing with the vec=[1,1,1] numbers ?

Hi , Thanks for the Text and Leader tip

If I want to import Y, X ,Z rather than X,Y,Z

Can I just switch around the
x=data[1].to_f.mm
y=data[2].to_f.mm
z=data[3].to_f.mm
pt=[x,y,z]

To
y=data[1].to_f.mm
x=data[2].to_f.mm
z=data[3].to_f.mm
pt=[y,x,z]

Yes.
The data[] order is the order typed in each line in the .dat file.
The original code assumed the first was the 'text', then x, y and z values, as in the .dat file supplied.
You can have the .dat file's entries in any order as long as the code's data[] values are adjusted accordingly - for example if the format were x,y,z,text then the values would all change around to suit with txt=data[3], and then x=data[0], y=data[1] and z=data[2]...
The code I gave you was only a basis for .dat file reading - it's very flexible...

PS: DON'T swap the point's values around use pt[x,y,z] always, no matter what the order they were read from the file !

Hi again
When I try to import a file Negative Co-ordinates I cet an error
Is this an easy fix ?

See the example file

Example_negative.txt

TIG

What's the error ? Please post examples...
The code x.to_f.mm should take the text 'string' of 'x' and make it into a 'number' [+/-] and then tell SUp it's in 'mm', not the default 'inches'?

Exactly what does the error say?

khallgren

Hi , I tried to make my own file for testing and the negative co-ordinates workes fine, so the problem is not the negative co-ordinates. But when I export a file from my calculation program and try it import it I get an error, but the files sceems identical to me?

Here is the error i get

and the file is attached below

Error: #<Errno::ENOENT: C:/Programfiler/Google/Google SketchUp 7/Plugins/cptstxt.rb:14:in `readlines': No such file or directory - C:\Documents and Settings\krh\Skrivebord\BeregnetHøyderfile8.txt>
C:/Programfiler/Google/Google SketchUp 7/Plugins/cptstxt.rb:14

BeregnetHøyderfile8.txt

I think I know what the problem is . Its the dicimales.... Its fine importing a file that says:

example: text,200.0,200.0,200.0

But when the file has a desimale value thats larger than 0 i get an error

example: text,200.5,200.5,200.5

Best regards
Kristoffer

thomthom

Ah!
I know why that is - because you are Norwegian! Sketchup's ruby doesn't read files that has characters which isn't ASCII (A-Z). So our beloved æøå makes SU's file functions go belly up.

I struggled for ages with this some time ago. Found no good solution for that. You can work around be renaming your file.

?? With the same file you tried earlier? Or did you create a new test file with just ASCII chars in the file name & path?

TIG

As Thomthom said -
It's an 'unrelated' error to the code itself... you have 'special characters' in the filepath - this always causes Ruby / Sketchup problems [it can be trapped form but it's a bit complex for this simple example code!].
So please do it without the 'ø' etc in filename 'BeregnetHøyderfile8.txt' >>> 'BeregnetHoyderfile8.txt' ? it should then work !

Hi,
@Khallgren: I'm just about to modify my points cloud script to achieve what you want. Stay tuned....

khallgren

Hi , Oppps I missed that issue
Diddler Bur: It would be great if your point cloud importer had a "text" option
Thanks for all your help
