Thanks dan.

hi,

I used to use:
b = file.gets()
c=b.split(" ")
to read lines from a data file in text.

but the following lines doesn't have a " " between two data if the value is negative.

0.208646094863E+000-0.513313617099E-001-0.915625940530E-003 0.180604789668E+000-0.240882759294E-001-0.872767876563E-003

How do I split them now?

Thanks in advance

hi,

I was wondering if I could get the index of an enums selection directly.

In my example below, I want to choose between "2D" & "3D" for one variable. The return is either "2D" or "3D". But I want the index number instead, that is "0" for "2D", "1" for "3D".

How could I get the "0" or "1" if I don't compare the return with the list of the enums.

Thanks in advance

Cean

def hw_inputbox
	
  iaxi=1	
  t_iaxi = ["2D","3D"]
  enums = [t_iaxi.join("|")]
  values = [t_iaxi[iaxi]]
  prompts = ["Geo type; "]
  results = inputbox prompts, values, enums, "my Geo"
  return nil if not results 
  $iaxi = results[0]
  your_slection=$iaxi
  UI.messagebox(your_slection)

end

UI.menu("Plugins").add_item("hw_inputbox") { hw_inputbox }

Hi,

How do I add an color line?

I use face.material="red" to change face color, but line.material doesn't work.

Thanks in advance

I tried "a.jpg".

Why ".jpg" is not listed in the "files of type"?

hi,

I want to generate component in anywhere with any angle upon my need.

I come up with this code. Now the angle is only about Z axis.

Any advice is welcomed.

Thanks for Matin's wonderful tutorial http://www.martinrinehart.com/models/tutorial

I read your wonderful web-page description of the 4 x 4 matrix - ...

I am reading it too. Great job.Thanks.

I read your PipeAlongPath code. I'm not using pre-selected path, instead generating by add_line+add_circle+add_line for U.

add_circle return an array of edge, I need to include them into the path array.

it works now (attached).

Thanks

draw a u-bolt

I'm tring with ruby.

tried follow me. But it can't follow an arc. Any suggention?

Thx

btw: I drop my line very soon each time I visit this site.Any problem?

Instead of writing every 'mm' in code, I thought it's more easy to draw as it is and scale back at the end.

That also cleared me from inserting a DWG file, need scale back to get the dimensions show in right number.

Thanks.

Thanks Dan. So, I was right. It was in inch.

It's a bit hard to understand the API:
"
The mm method is used to convert a number to millimeters.

It returns a Length value which is the same length as the given value. For example len = 25.4.mm returns 1 inch.

Returns:

mm
    a value in millimeters if successful

 value = 10
 mm = value.mm

"

The result is the same length but with a different unit.

Hi,

I want to draw an U bolt (no thread now) with Ruby, thought I need FollowMe command. Is there a FollowMe example?

Thanks in advance

Hi,

I use the following code to draw a r=100 cyclinder. With the SketchUp runing in Archi mm template, what I got is a r=5080 cyclinder which is 25.4 times bigger. Thought it is in inch.

I was wondering should I specify what template to use in my code? If so, how to do that?

Thanks in advance

Cean

def my_cylinder

    x=0
    y=0
    z=0
    idir=1
    r=100
    h=500
    
    model = Sketchup.active_model
    
    $entities=model.entities
    
    p1 = Geom;;Point3d.new(x,y,z)
    vector= Geom;;Vector3d.new(1,0,10)

    circleI = $entities.add_circle p1, vector, r
    base = $entities.add_face circleI
    base.pushpull h


end #def hw_cylinder

UI.menu("Plugins").add_item("my") { my_cylinder }

Hi TIG,

Finally made it and got my mesh.

To cut through, need to cut from the opposite direction.
To cut in (make a shell), need to cut from outside to inside.

No need to do all the |e|e.erase! ... check.

Thanks

Now the problem is un-wanted face. I added labels on the photo.

the PFC channel is not out.

Not understand all this code below. Must be something wrong.

    @entities.to_a.each{|e|e.erase! if e.valid? and e.class==Sketchup;;Edge and edge.faces[1]==true and edge.faces[0].normal==edge.faces[1].normal}

I am trying to carve the ladder out from a big cube.

New code, new approch and new problem.
