[Plugin] Color by Slope
-
Don't worry about 'xxx' and "xxx" these enclose a text string xxx - and they are often synonymous.
Although 'escaped' characters [\n etc] behave differently inside them.A require statement is simply a way of ensuring that a file is loaded before the rest of the code. If it has already been loaded [for example by a script that loaded earlier] then it's skipped over this time. Some special functions are created by the sketchup.rb so it's often 'required' in scripts, the progressbar.rb adds a visual progressbar in the status text to show you how far along the processing has got.
You don't need to worry about a required file's location.
Sketchup's own files [like Sketchup.rb] are kept in the Tools folder.
The vast majority of others go into Plugins folder, as directed by each tools installation notes...
As Ruby files are auto-loaded as Sketchup starts a system array is read -$LOAD_PATH- by default this includes the path to the Plugins folder and then Tools folder - so 3rd party tools add extra paths to it at startup so that Sketchup loads files from additional locations as well. Files load in alphanumeric order so 'aaa.rb' loads before 'xxx.rb' from Plugins. Because 'sketchup.rb' loads later on from the Tools folder it's important that scripts loading from Plugins 'require' it so it's preloaded to be used by their code.
Some rogue/misguided scripts add an old 'Sketchup.rb' file into Plugins. If so then please remove it; the only copy should be the one installed by Sketchup itself, and that must be in Tools.
'Compatibility Files' can cause unexpected issues - ensure your security permissions to all files an subfolders within the Sketchup folder are set to 'FULL'. This is particularly important for the correct installation of scripts and their subfolders of helper files inside Plugins, and also not frgeting the Materials, Components and Styles folders, where you may wish to use 'save_as' for some aspects of your models, or to keep 'libraries' of others bits... -
does this script work for 2013? I tried downloading from the extension warehouse and got some odd error messages. Next I tried the smustard download and installed in the plugin folder (along with progress bar plugin), restarted sketchup, checked my plugin section and do not see it any where. Am I missing something? I would love to try this out.
thanks for any help you can shed -
What were the "odd error messages"?
-
I tried it again to get the direct quote and this time it worked. It may be that I tried the extension warehouse first then smustard. When looking at the smustard site it listed the prerequisite ruby (progress bar) which I installed.
If this were true it would raise the question: does the extension warehouse (via SU) give a warning or list of prerequisite scripts?
-
Requires progressbar.rb probably ought to be included on the Extension Warehouse page. It should be indicated in the first post of the original thread here on SCF. The error message you got most likely would have indicated that progressbar.rb was missing as well.

Thanks for the quick help, its working now and great for what I am doing

Weird, I'll try to test the version on the warehouse. The one on the EW should not need progressbar though. I removed that dependency from that version. But maybe I introduced a bug in the process

Hello Chris!
How it possible to do, what plug in coloring face by slope range?
For example 0-10 red; 10-20 orange; 20-30 yellow...............
I really need this function to analyses terrain by slope.Thanks

Maybe "Color By" by Sdmitch? (not retested)

Hello Tig (and Chris),
Thank you to you both for the original colr by slope ruby and the modifications to it to show colors for various slope angles. I have found the rz. file but it is unclear what needs to be edited and replaced. Is a new color by slope plug in for the various angles available?
Thanks again,

Now edit/replace the version that's still in the Plugins folder, as set out above [open with Notepad.exe or equivalent plain-text editor].
Save it and restart Sketchup - all slopes should now be colored in the angle-ranges and colors you've specified...
