Hello.

I'm trying to print out two numbers from a script where the user inputs a wall thickness and wall height. An inputbox takes the two prompts and is supposed to spit it out on the screen.

UI.messagebox accepts 1 or 2 variables. The first is a text string. The second determines what buttons appear. Within the text string, you need to enclose the thickness and height variables in curly brackets {} preceded by a # symbol as demonstrated below

UI.messagebox("#{thickness}, #{h}",MB_OK)

Option 2 would be to convert the thickness and height variables to strings and add them

UI.messagebox(thickness.to_s + ', ' + h.to_s)

Hi Sam, I note above you said you haven't considered converting this plugin for metric use and TIG has outlined how to 'metricate' it. I'm a little unsure how this is done; Do I try and open the script and edit it? A little risky given I nothing about coding....

Cheers.

Better leave it to the "professionals". I'll take a look at it and PM you a copy to try.

The plugins are loaded alphabetically it seems so I have just added a "AAA" prefix to the name of the one I want to load first

Is there some point clouds plugin better that "Undet"? (Undet is full of bugs ,and You must pay for that a lot) .
Thanks for some advice.

Go to Plugins forum http://sketchucation.com/forums/viewforum.php?f=323 and search for "point cloud"

I am using an If else statement, I got it to work earlier in the code, but now I am having an issue grouping a new entity and finding it's face, it has to do with adding an arc and not adding an arc.

It seems to me that you define 'edg' twice if l=="Yes" but don't define it at all if l=='No'.

#ROUND Nose Yes/No<<<<<<
if l=="Yes"
  puts "top hanger round nose"
  #add arc<<<<<<
  edg = ent5.add_line [0,b+3,b-c], [0,b+3-0.5,b-c] ;vrt1=edg.end
  ent5.add_arc [0,b+3-0.5,b-(c/2)],[0,0,b+3-1],[-1,0,0],-c/2.0,0,180.degrees,12
  edg =  ent5.add_line [0,b+3+h,b], [0,b+2.5,b];vrt2=edg.start
  #end Add Arc<<<<<
else
  puts "top hanger square nose"
  edg=ent5.add_line [0,b+3,b-c], [0,b+3-1,b-c]#<<<< edg
  ent5.add_line [0,b+3-1,b-c], [0,b+3-1,b]
  ent5.add_line [0,b+3-1,b] , [0,b+3+h,b]
end
#add the face to the entities in the model
edg.find_faces; face=edg.faces[0]
face.pushpull wdth

BTW, how can I change the units to cm? I tried writing "cm" and " cm" after the number, but got an error.

The syntax is ".cm", so 1.inch = 2.54.cm

Hi!

I'm attempting to make a split model for 3d printing and I'd like it to have joints to get a firm grip when assembled (like a lego).

This is what I have:

Does anyone know of a plugin or a way to get this done?

Thanks!

Here is a start. You will need to change the values to suit your situation.

unless file_loaded?((__FILE__))
	UI.add_context_menu_handler do |menu|
		sel = Sketchup.active_model.selection
		if sel.first.is_a?(Sketchup;;Face)
			menu.add_separator
			menu.add_item('Dimple') { 
				face = sel.first; ctr = face.bounds.center; nrm = face.normal
				cir = Sketchup.active_model.active_entities.add_circle(ctr,nrm,0.125,12)
				pts = cir.map{|e|e.vertices}.flatten.uniq.map{|v|v.position}
				fac = Sketchup.active_model.active_entities.add_face(pts)
				fac.pushpull -0.25 if fac
			}
			menu.add_item('Pimple') { 
				face = sel.first; ctr = face.bounds.center; nrm = face.normal
				cir = Sketchup.active_model.active_entities.add_circle(ctr,nrm,0.125,12)
				pts = cir.map{|e|e.vertices}.flatten.uniq.map{|v|v.position}
				fac = Sketchup.active_model.active_entities.add_face(pts)
				fac.pushpull  0.25 if fac
			}
		end
	end
	file_loaded((__FILE__))
end

Hello,
b & d are variables, rise and run are calculated from b & d.

for this example rise=d/6 and run=(b-(1+e))/5

I just put in the numbers so the code can easily be copied and run

As I see the problem then is that points 4 & 5 need to be calculated.

mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
vue = mod.active_view
Sketchup.active_model.entities.clear!
vars = UI.inputbox(["b;","d;"],[51.5,46.5],"Routed Stringer")
if vars
  b,d = vars; e = 0.5
  run = (b-(1+e))/5.0
  rise = d/6.0

  #<<<routed stringer
  group = ent.add_group(); group.name="Routed Stringer"

  ent6 = group.entities
  pts = []

  pts[0] = [0,b-(1+e),d]
  pts[1] = [0,b-(4+e),d]
  pts[2] = [0,-3, rise]
  pts[3] = [0, -3, 0]
  #calculate pts 4 & 5
  vec = pts[2].vector_to(pts[1])
  v = vec.axes[1].reverse
  tpt = pts[2].offset(v,11.25)
  pts[4]=Geom.intersect_line_line [pts[3],[0,1,0]],[tpt,vec]
  #pts[4] = [0,(run+2.5)*0.4256, 0]
  pts[5] = Geom.intersect_line_line [pts[0],[0,0,1]],[tpt,vec]
  #pts[5] = [0, b-(1+e), (d-12 )]

  #add the face to the entities in the model
  face = ent6.add_face pts
end

Are b,d,e,rise,run all variables?

Use Move Tool to move top center of the cylinder to an edge of the face you want to align to. Use Rotate Tool to get the cylinder perpendicular to the face. Use the Move Tool to position cylinder on the face

@pbacot said:

It does work.

What I have is nested components from CAD, which are no use for me in the SU model as components, except as reference. Still I must go into each level (context) to find the components. The components clutter the component list and probably make the file heavier.

Would you want to change the nested components into groups also or just explode them?

@jgb said:

Thanks SDMITCH

Got the .RB and put it in my /plugins folder. Started SU. The Comp list was unchanged (as expected) so I pulled in a few that had been renamed. And, yes, the comp name was changed to the file name.

I figured I had to re-save as and replace the old file, which worked.

Just 124 to go.........

Sorry it didn't work for you. It seemed to work for me. It is doing exactly what you are doing, loading, renaming and save_as.

@pbacot said:

Happy Holidays! Hey is there a plugin to change all the components in a drawing or selection to Groups???

A one-liner for component instances in a selection

mod=Sketchup.active_model;ent=mod.active_entities;sel=mod.selection;cis=sel.grep(Sketchup;;ComponentInstance);mod.start_operation "ToGroup";cis.each{|ci|ent.add_group(ci);ci.explode};mod.commit_operation

Please check PM's for possible solution.

@paciente8159 said:

Is this OK?
The same principle. A raycast from the testing point. I'm only counting how many faces it sees in one direction and only if the point hits the face on the inside (from the testing point)
To also include the outter shell of the solid the point classification must be changed to validade Vertex and Edges hits.

Thanks

Here is the code

def point_insidesolid?(point, solid)
> 		return false unless solid.manifold?
> 
> 		#vector that goes through the origin
> 		vec = Geom;;Vector3d.new(1,0,0).normalize

It should if "point" is truly inside the solid. If it is a model point then it will need to be transformed by the inverse of the solid's transformation.

I agree with Dave. If you put the line and curve on the xy plane and aligned with the x axis, it works everytime.

@chrisik said:

Is there a plugin out there that can quickly measure the distance of the midpoints of two selected groups and/or components in all 3 dimensions and direct distance. Or is somebody out there that can write this little plugin? thanks.

Something like this? First select 2 components and/or groups then right click on either one and select 'Calc xyzd'.

unless file_loaded?((__FILE__))
	UI.add_context_menu_handler do |menu|
		sel = Sketchup.active_model.selection
		if (sel[0].is_a?(Sketchup;;ComponentInstance)||sel[0].is_a?(Sketchup;;Group))
			if (sel[1].is_a?(Sketchup;;ComponentInstance)||sel[1].is_a?(Sketchup;;Group))
				menu.add_separator
				menu.add_item('Calc x,y,z,d') {
					center0 = sel[0].bounds.center
					center1 = sel[1].bounds.center
					x = Sketchup.format_length((center1.x-center0.x).abs)
					y = Sketchup.format_length((center1.y-center0.y).abs)
					z = Sketchup.format_length((center1.z-center0.z).abs)
					d = Sketchup.format_length(center0.distance(center1))
					UI.messagebox "x = #{x}\ny = #{y}\nz = #{z}\nd = #{d}"
				}
			end
		end
	end
	file_loaded((__FILE__))
end

I'm trying to figure out how to flatten a pipe/cylinder...

@ntxdave said:

OK - I finally found it and am using it but have a couple more really dumb questions/comments:

• When I used Hide if Not it did exactly what it was supposed to however, how do I get back to view my entire model.
  Edit>Unhide>All should do it.

• What are the other entries under the SDM Tools (Edge Tool, CorG Tool, Misc Tool)?
  It was my attempt to make things more logical by making the plugins that use and/or create those type of entities.

I have no idea how you determine what @ptw1616 is but another option might be creating an array of the locations like this

# Draw Circle on selected ceiling geometry - Cut Hole
mod  = Sketchup.active_model
ents = mod.active_entities
sel  = mod.selection
face = sel.grep(Sketchup;;Face)[0]
@vec3 = face.normal; @Ldia=1.5; @Lthick=0.25; @Ldepth=0.25
locations=[[1,2,0],[3,2,0],[1,4,0],[3,4,0]]
locations.each{|loc| @ptw1616=loc
  ents.add_circle(@ptw1616, @vec3, @Ldia/2, 24)
  ents.to_a.last.erase!
  # Draw Recessed Light
  tube = ents.add_group
  tube_inner = tube.entities.add_circle(@ptw1616, @vec3, @Ldia/2-@Lthick , 24)
  tube_outer = tube.entities.add_circle(@ptw1616, @vec3, @Ldia/2 , 24)
  cross_section_face = tube.entities.add_face tube_outer
  inner_face = tube.entities.add_face tube_inner
  tube.entities.erase_entities inner_face
  cross_section_face.pushpull -@Ldepth, false
}
