e is most likely valid. When e does not have a material assigned, the .material method returns nil.

results, as returned from inputbox, is an array.

Thanks! Will do it now.

Is there a PDF available with the V6 Ruby Help topics? I got the SketchUp V6 users guide on PDF. Wondering if there is one for Ruby Help.

Thanks, Todd

There are all the options accessible from Ruby (unless I missed some). I don't see autosave anywhere.

Should be doable. I'll look.

model.entities.add_arc([x+@dist, y+@dist, z], vecx, vecz, @d/2, 0, pi/2, @s)
model.entities.add_line([x+@dist, y+@dist, z],[x+@dist, y+@dist+@d/2, z])
e=model.entities.add_line([x+@dist, y+@dist, z],[x+@dist+@d/2, y+@dist, z])
e.find_faces
e.faces.first.pushpull @thick

do I understand the following correctly?

"e",collects the 3 entities (arc, line & line)

"e.find_faces" ,then makes the face out of the entities

now what does "first" do because without it pushpull still wont work?

tia

You are right - I misread. No, you don't understand correctly. But you will soon enough.

@unknownuser said:

"e",collects the 3 entities (arc, line & line)

No. This assignment to "e" only assigns that last line (edge). You only need to .find_faces on a single edge for a closed loop of lines in order to get a face. So, your assignment is correct. You could have performed the .find_faces on the other line, or, any segment of the arc, and you would get the face like you want.

@unknownuser said:

"e.find_faces" ,then makes the face out of the entities

Basically, yes. The method looks at the edge you pass, then goes through all edges connected to the edge you passed, and for every closed and coplanar loop of edges that can be found, faces get made.

@unknownuser said:

now what does "first" do because without it pushpull still wont work?

The .first method will pass the first array element to pushpull. Your code is:

@unknownuser said:

e.faces.first.pushpull @thick

e is an edge.
e.faces is an array of all the faces that use this edge.
e.faces.first is the first element (the first face) in the faces array.
e.faces.first.pushpull calls the pushpull method for the passed face. (e.faces.first).

See the doc here: http://www.ruby-doc.org/docs/ProgrammingRuby/ for the Array class and its methods.

The .pushpull method is defined to be called for a face, not for an array. When you use the .first method on the faces array, you are picking a random face (the first one in the array at position face[0]), and it will pushpull just fine. Note that you are doing nothing in your code to identify the exact face you want to pushpull - you're just picking, essentially, a random face. So, yes, the pushpull works, but no, it's probably not acting on the face you want. If it is acting on the face you want, they you are a lucky person, because of all the newly created faces, the one you wanted jut happened to be the first one in the array.

Todd

That won't work. I don't have time now to respond, but will later tonight.

I've posted the code to do this somewhere before. Perhaps in the old pro Ruby forum. Maybe you can search on "find_faces" and "pushpull" to locate it.

Todd

The code you have won't work.

"e" is an edge. e.find_faces works for edges, so it's good.

e.pushpull will never work, 'cuz .pushpull only works on faces.

Remove the e.pushpull, do what I said in the first post to come up the new face, and then do the pushpull on that face.

Todd

Before the .find_faces, do an inventory of all the faces in your current entities set.
After the .find_faces, do a second inventory of all the faces in your current entites set.
Subtract the first inventory from the second.
With the remaining elements, find the face with the same normal as the one you pushpulled.

Oops.

Command = 1048576
Alt = 524288
Control = 262144

The Command key, also known as the "apple" key, shown as a ⌘ in the Doc, is the Mac equivalent to the PC's CONTROL key. The control key on a Mac isn't used that often.

The ALT key is also named the Option key.

Todd

Ignore any logic you see - this is from an old copy of a script. They keycodes are good though, for both Panther and Tiger, and I suspect they will be the same for Leopard too.

BTW, in OS X "Tiger" 10.4.10, the RUBY_PLATFORM constant is "fat-darwin8.8.0". If you check for "darwin" that should be good enough, thru Tiger anyways.

Todd

Yeah, in the onKeyDown method, the keys are not OR'ed.

You'll figure it out. Again, I recommend adding a "puts" statement as the first instruction in your methods to show the key code and you'll what see gets passed when.

Todd

In my nudge script, I check for either the Shift Key or the Control key. I use the onKeyDown and onKeyUp methods to test for either key. When either key is pressed, I set a corresponding true toggle for that key. When it's raised, I set the toggle back to false.

Finally, when I'm looking for the arrow keys, I test for true for either toggle and adjust the move distance accordingly. For instance, SHIFT+any arrow key is a 10X movement in distance.

Todd

Well, define your use of "coplanar". Coplanar means "on the same plane". So:

if face1.plane == face2.plane then puts "faces are coplanar" ; end ;

Now, if you also mean 100% "coincident", then the defined bounding box of each face will match.

If you mean partially overlapping, then tests would have to be made with various points (vertices) on one face with the bounding box of the other face, and then vice versa as well.

Todd

No can do. The good news is that it's on the slate for V7.
