SketchUp RUBY API Wishlist [way of coding wishes, please]

billbell52

Maybe I am thinking about this wrong but I think a good idea is to develop a rubygem that exposes the SketchUp Ruby API to a standard ruby install. You can continue to develop the embedded Ruby capability but a lot of existing Ruby capability/code/gems can be put to immediate use. The relieves the pressure to urgently add capability that exists someplace else. For example I may want to couple SketchUp to a RubyOnRails environment. I don't expect you to embed ROR into SketchUp. I would have the capability of doing it on my own if I could access the Ruby API from a standard Ruby install.

Also, as I understand the Sketchup Ruby API is based on 1.8.0. Exposing the Ruby API to an external Ruby environment would allow users to use a more current release.

Does this make any sense?

This is music to my ears, Scott. Here's another vote for ruby control of dimension objects. CB.

nice post!
ok, how about this my officemate send me a cad file to be SU, problem is when i import them to SU the lines in 2d are not they seem to be.. they are in different axis can SU place it in one axis,

(is this an existing ruby script?
if so kindly send to me)

How about a method to refresh the SketchUp display when executing long scripts? Today the interface looks like it is frozen when you change focus to another window and then back to SketchUp. The display gets refreshed only when the script completes or a dialog box that requires user input is displayed.

I'm experiencing the same problem with a routine that generates thousands of faces. The calculation is sometimes very long, but with the screen locked is impossible to understand the percentage of completion and when the calculation will end.
You have found a solution in the meantime?

I have a SketchUp RUBY API Wishlist:

A ruby script that coverts multiple lines to 1 whole line.
A ruby script that speeds up shadow rendering.
A ruby script that ables a follow-me tool to cross multiple lines "For example: a cross using any shape"
A ruby script that Measures a volume of a model in Gallons, Liters etc..

Have a look at weld.rb http://www.smustard.com/script/Weld

That would need to happen in the core SU code i.e. google needs to do that.

Hard to know what you mean without more details. Could you post a pic in a new thread?

There are a couple of volume scripts out there at the moment. Id guess it would be a fairly simple task to convert their output to litres/gallons. This would be a good place to start: http://forums.sketchucation.com/viewtopic.php?f=180&t=3188

p.s. I think this thread is meant more for wishes regarding the ruby API itself, rather than individual scripts.

My Volume scripts already let you select the results in gallons [US and UK] and litres as well as most other volume units...

Being able to set Layer colour.

thomthom

Being able to set Material name.
Being able to delete materials.
Being able to delete ComponentDefinitions

TIG

You can delete a definition's instances and then that individual definition from the component-browser thus:

model.start_operation("Delete Instances and Definition")
  definition.instances.each{|instance|instance.erase! if instance.valid?}
  # this 1st step is optional since all instance become nil anyway when the definition is emptied
  definition.entities.erase_entities(definition.entities.to_a)
model.commit_operation

Assumes you have set model and definition... It empties a definition and therefore it disappears off the browser listing. It must be inside an operation to work.

PS: You can delete a material BUT it's pretty convoluted. I'll publish a script for it shortly...

thomthom

I've not had 100% success with deleting definitions like that. I seemed to run into bugsplats. But I'll do new tests.

As for materials, I seen how V-Ray for Sketchup renames and deletes materials:
Deleting: iterate the whole model and remove the material - then apply unused materials to dummy groups and purge.

Rename: Create new material identical to old with new name - iterate and replace the old material with new. Then run the Delete method.

Ugly hacks which I'd rather not use. When model grows in size this just bogs down.

TIG

I've also made the equivalent layer.delete method here http://forums.sketchucation.com/viewtopic.php?p=166985#p166985 ...

TIG

http://forums.sketchucation.com/viewtopic.php?p=166978#p166978 has material.delete method - I've streamlined it as much as possible ???

TIG

I've also made a material.name="new_name" method here http://forums.sketchucation.com/viewtopic.php?p=167219#p167219 ...

TIG

material.name="new_name" method now v1.1 - here http://forums.sketchucation.com/viewtopic.php?p=167219#p167219
Temp folder fixed for Mac users...

Be able to track the shadow area on each face. This could make the calculation of shading possible for energy simulation.

• to have the 5th (optional) argument for write_image as 'Transparent Background' if the file type is .png

Sketchup::load

The Sketchup::load method does NOT expose the wrap argument, so we can specify wrap=true for rbs scripts.

For some unknown reason, the Google team defeated, or just didn't pass the 2nd argument (wrap) on to the aliased standard load, when they overrode it to handle rbs decrypting.

Please fix this!

Here is my list:

Tig, although your solutions on material.name=, layer.delete, material.delete are good, it seems to me it would be much easier to just have them in the API. So i second the proposals of ThomThom
Also i second the proposal of Morisdov concerning the add_framechange_observer not firing when creating movies or when working in layout. It should fire there to.
make the entity.id consistent throughout different SU sessions (it changes now from time to time)
it would be great if you could just select an entity based on a parameter (eg. entity.id) without looping all the entities in the model
being able to access the font/size and other parameters of a text
make a difference between the execution of scripts and the interface so it is possible to incorporate a 'stop script' button for example. Now the interface freezes as long as scripts are running. This makes users believe the execution of the script has halted and Sketchup has stopped working.
...more to come

And it would be faster.

Ditto!

@pout said:

Ditto. If you have a script that requires observers attached to some objects one want these to be reattached when the model is loaded. Currently one has to iterate the whole model to find the entities, and one has to attach an attribute to be able to find the correct one - which means string comparisons which are really slow.
So a better way to directly reference entities across sessions would be a great addition.

while true puts 'Ditto!' end

does anyone know if any of the remarks here will be taken into consideration in a new version?
