[Plugin] Component Spray Tool 1.3.

csolar

I've just installed this (SU 7.1, WinXP), and I have a question about the spray pressure parameter. In the user guide it says that the # of components dropped is calculated as:

[area of surface]/[average area of component(s)]*[spray pressure]

In my case, the surface is a 10x10 square, and the component is a 1x1 square -- so the surface is 100 times the component area. If I select a spray pressure of 10%, I would expect 10 components to be dropped, but what I get is 100 components. Basically this calculation seems to be off by a factor of 10: if I ask for 100% pressure, then 1000 components get dropped, and so on.

Am I missing something? I ask because for my model I really need lower densities; i.e. in line with the calculation described in the guide.

Thanks,

Chris.

Another observation:

I select "random rotate", but when I look at the results it's clear that only 6 specific rotation angles are being used...actually more like 3 pairs of angles, 120 degrees apart, with the items in each pair being 8 degrees apart. Is this expected?

Thanks, Chris.

Hi csolar,
Do you have set any angle snapping ?

Hi Didier,

Any chance of adding what Solo and I have requested...??

I did, but the results are the same after I turned off angle snapping.

Yes. The only question is: when ?

Didier:

If you replace the native model.raytest with this method the rays won't stop on invisible entities:


  # Raytrace method that does not stop on hidden entities.
  def self.raytest(ray)
    model = Sketchup.active_model
    vector = ray[1]
    while true
      # Shot ray
      test = model.raytest(ray)
      return nil if test.nil?
      # Verify visibility
      point, path = test
      if path.all? { |e| e.visible? && e.layer.visible? }
        return test
      else
        # raytest stopped on a hidden entity - create a new ray from that point
        # and let the loop continue until it hits something visible, or nothing.
        ray = [ point, vector ]
      end
    end # while
  end

Hi tt,

thank so much

Problems with component spray tool...Tool will not pick point after clicking.
Is anyone else have problems with the tool? All the parameters appear correct.
I'm placing byce on a simple plane is not working. Openig a new drawing helped but it always goes back to not working at some point.

I'm using in V6.

Hi,

I wanted to try compo spray but I get a huge number of components at a small circle. What am I doing wrong?

Didier Bur

Hi,
Did you draw a great circle (20m or so) or a small one (2m or so) ?
But don't worry, since FaceMe components don't really have a bounding box, the number of components to be created is wrong, if I remember well...
Regards,

Hi Didier,

The circle was about three meters. I tried the whole day. If i use it at a single line or a point then i get very small copies.

For the above mentioned problem i found the solution. The values for Low and high scale where to less.

But now although Keep vertical is selected, the tree is horizontal. For this I could not find the reason.

Hi,

I found the error. This component was the reason. After I exploded the component and made it a new component, the error was gone.

I'm having difficulty to make it work in SU 8.
Confirmation ?
But it is my first try, I must say.

Exactly what isn't working?

mariocha

Well, like I said it was my first try. I finally got it after a few more tries.
My mistake was to try to "spray" on a face in a group being outside of it.
Somehow I assumed that's what it did.
Maybe cause I cannot get the "selection" option to work. It just stops and asks to select objects, even when a face is selected before, and it stays suck there, clicking or enter do nothing.
I read the manual, again (very well done btw). Maybe a warning line could be added about groups.
Although it is so obvious now.

Hi all,
Here is an update of the component spray tool (updated PDF doc included).

What's new in 1.3.:
New "shape" option to drop component at each vertex of selected faces.
Bug fix when loading the script on Mac.
Bux fix that froze the script when no destination layer were specified.
Enjoy !

EDIT:
Last version posted 03.09.10 (no more progressbar conflict, not an rbs)

This is my problem with the plugin, can you tell me how to fix it? The table is to big, It isn't match with my screen so I can't see the rest of the table.
