Hi,

I have a problem with the error message 'reference to deleted Entities' when i run the code i made.

My work was to indicate my code in another way.

At first, the structure of code was

` toolbar = UI::Toolbar.new "Name"
....
toolbar.show

def Name2
model = Sketchup.active_model
entities = model.active_entities
...
inputbox
...
entities.add_face
....
selection = model.selection
...
end`

That is a simple code to make a inputbox. And now, I am trying to make webdialog(Actually, I refered to other posts on this site for making my own codes, Im very thankful to all users here) and the code is shown below

` def Name3

@model = Sketchup.active_model
@entities = @model.active_entities
...
HTML
...
@entities.add_face
...
end
Name3`

This is the simplest code to make a webdialog. The result of running both codes above is same. I just tried to change 'inputbox' way to 'webdialog' way. Since I know the structure of both codes very well, it looked like it has no problem. But, I could see the error message and it was started since the line @entities.add_face which can be seen above(Error: #'reference to deleted Entities' C:/Users/name/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/practice.rb:112:in `add_face').

What Im wondering is the webdialog was run very well for other codes. Only one code isn't working with the error message 'reference to deleted Entities'.

Is there someone who knows the error message? Please help me solve the problem.

Hi. I'm facing to an unexpected problem. The problem is simple.

I made a plugin which creates cone shape and it can be placed after inputting coordinates in input box. Here, I inputted (1000.mm, 1000.mm, 1000.mm), but the cone was placed at '991.mm, 991.mm, 991.mm). Why did it happen??

FYI, I used 'class' method and a = Geom::Transformation.new([@@x.to_i, @@y.to_i, @@z.to_i]). Is the problem related with what i have coded?

Thank you, sdmitch and TIG. I could partly understand how i have to fix the codes, but not perfect because I showed you code roughly. Maybe, it would be better i show you what i'm doing now. I'm trying to add bezier curve to draw one simple shape. The equation for the quadratic bezier curve represents as shown below

B(t) = (1-t)(1-t)P0+2(1-t)P1+(t)(t)P2

With the equation, I tried to generate coordinates which are from the equation and wanted to use 'For loop'. hmmm It looked like i can make the codes by myself, but didn't work well

Hi, I'm looking for how to generates coordinate with an equation and connect the coordinates adding line or curve with ruby.

My idea was

ents = Sketchup.active_model.entities
pt0 = [a,b,c]
pt1 = [d,e,f]
pt2 = [g,h,i]

for k in 0...20

x = eq*pt0.x + eq*pt1.x + eq*pt2.x
y = eq*pt0.y + eq*pt1.y + eq*pt2.y
z = eq*pt0.z + eq*pt1.z + eq*pt2.z

pt3 = Geom;;Point3d.new(x, y, z)

end

ents.add_line pt3

pt0, pt1, pt2 are basic coordinates. 'eq' means random equation. We can add any equation with a variable 'k'

I know there are some errors, but don't know how to fix it. I wish 21 different coordinates are generated from the 'for loop' and they connect each other to draw a line. Can you help me?

Hi, TIG. Finally, Its working as I have hoped. This is the corrected code. I needed not use 'group'. The cone shape is created after I deleted the line. Thank you!

Thanks you for a kind comment, TIG, but it's not still working now. There is no problem until adding numbers in the inputbox. The problem is nothing shows up after clicking 'ok'.

Thanks you, slbaumgartner. Now its working well
However, this is the first step for drawing cone. The main goal is to draw cone freely.
I'm trying to add inputbox with the corrected code you gave, and have already made codes that can draw various shape with inputbox, but it didn't work again. In my view, there is no problem. Could you please look over it again?

Hello, I'm practicing making code by myself and got stuck on error. I can connect arc with a line from 0,0,0. but can't add one more line that connects between 0,0,0 and the other side of arc. I wish one icecream cone shape will show up after executing codes.

Thanks, sdmitch and slbaumgartner. Now It works well

However, I'm planning to create some shapes more with this way and actually made few shapes. I'm worrying about increase of icons in Sketchup, and am making ideas how to simplify tools.

1. Making dialog box
   I saw some free tools which 'inputbox' is added together. If the shapes can be individually selected in inputbox, I need not add icons anymore, but don't know how to make it. I know basic codes for creating inputbox, and would like to apply the basic code to what I want(choosing each shapes individually in inputbox). Additionally, Is it possible to add shapes which are saved in .skp file(I know how to load shapes saved in .skp file by using 'Class' method and how to place it on Sketchup space clicking) into inputbox too?

2. Using webdialog
   If i create webdialog box and add all icons into the webdialog by making tables(categorization), This way may look good as well. I'm trying to use

dlg.add_action_callback("") {|d, p|Sketchup.send_action ""}

Can i utilize this command for making icons in webdialog? I mean, the command looked like only basic tools(Undo, Redo, New, Cut, PushPull) can be used with the command. For example

dlg.add_action_callback("Undo") {|d, p|Sketchup.send_action "editUndo:"}
dlg.add_action_callback("Redo") {|d, p|Sketchup.send_action "editRedo:"}
dlg.add_action_callback("New") {|d, p|Sketchup.send_action 57600}
dlg.add_action_callback("Open") {|d, p|Sketchup.send_action 57601}
dlg.add_action_callback("Save") {|d, p|Sketchup.send_action 57603}

As you know, these actions are used in HTML and '<scrip> </script>' connects between ruby codes and HTML codes for indicating icons in webdialog. How can I make my own Sketchup.send_action? If it is possible, I will add the icons into webdialog.

Hello, I have a problem in making box. I would like to add box on space by adding an icon, but it didn't work well. is there anybody who can fix the code?

Configure the Command's appearance

box_cmd.tooltip = "Box"

Create and configure the Toolbar

box_toolbar = UI::Toolbar.new "box"
box_toolbar.add_item box_cmd
box_toolbar.show`

For better understanding, I attached two images more. I got a example of ray casting on google and wanna express it into second picture. As you can see, This is just combination of cone and cylinder. If ray casting is added, invisible area behind cylinder should be occurred. In other word, all parts of cone shape behind cylinder automatically have to be deleted. I would like to apply ray casting into usual shapes

Hello. I've ever posted this question once, but there were no replies.
I wanna get idea for expressing ray casting effect in sketchup. An attached picture is what i want. Is there anybody who can give me ideas or can share tools? I'm waiting your kind replies

I am looking for idea we can draw 3D figures partly removed by consideration of existence of obstacle, shade and so on. The ultimate purpose of this work is expressing camera coverage with cone figure like below picture. Unfortunately I didn't have any idea how to develop this work. You know, it is not simple placement of figures. I would like to automatically remove part behind obstacle in given space. Is there anybody can help me?

Ok, Thanks, Dan

I will be able to fix it by myself )

Thank you!!

I am a beginner in learning Sketchup with Ruby. Now, I am practicing coding from existing .rb files. Below code is one of examples. You will be able to place the figures in .skp on cartesian space if you run this script(you need .skp files, images for making icons).

I would like to run this script in another way, submenu. I hope all figures are placed wherever i want after selection in input box, not clicking icons. It will be my pleasure if you give advices.
