What I want is the image in green (bottom right).
The way to get there is what I think can be much easyer.
How I tried to do:
1 - Imported a DXF image and use “offset shape” tool on them resulting im the red image (Upper left)
2 - Create a rectangle with “Create Rectangle” tool, using “create array” tool create an array of the rectangle, gave it same width and height of the dxf offset result image and group it (bottom left blue image).
3 - Center both images one on top of the other and used the “boolean intersection” tool (red arrow). The result is the image on the upper right corner.
I thought this was enough. My question is: What did i do wrong for some of the vertical lines disapear?
To obtain the green image (bottom right) I have to use “draw line” tool, create an array of that line, group them and give the same width of red image. Put both images one of top of othr and centred. Then, one by one, adjust the height to the upper line of the red image.
Question 2 - What is the specific word to what I intend to do?
Thank you for your patience.
Have a nice Sunday!!!
I can somewhat recreate what you’re getting. I say somewhat because in my case I get no shapes from the lower-left preserved. I assume this is because in your example that the vertical pieces are not all perfectly aligned such that there is no space between shapes.
I can’t think of a single step way of doing what you want. Here’s a multi-step workaround.
Using your same setup first duplicate the top-left shape
After aligning the top-left shape with the bottom left shape, select every other vertical strip from the bottom left shape and group them. Do the same for the other half set.
Select the top-left shape and one set of the grouped vertical strips and complete the Tools->Boolean intersection.
Repeat for remaining top-left shape and other grouped set
I’m convinced that I’ve already seen something in a tutorial that shows something of the genre, but as I don’t know the term of what I intend to do, I don’t know what words to use in the search.
Can anyone else help?
I’m still looking for a easier way to achieve it.
This is not what I would have expected. Are you sure you selected ever other vertical piece when doing the intersection? The selected shapes cannot be directly adjacent to each other.
Definitely something weird happens!
I created the same example in the existing project and created the example in a new project, the result is the same. I have to do the test on another seat to see what happens…
I never selected only half! That’s the issue, I grouped all the array or 10 duplicated (“Edit” - “Copy”; “Edit” - “Duplicate”) rectangles at the same time, if they are side by side connected only half of them appear, if they are apart all of them show up.
I made somes examples to show the result with described steps.
1 - Draw a rectangle shape
2 - Do the array or duplicate rectangular shape. Array = using the array tool. Duplicate = Selecting “Edit” then “copy” or Ctrl + C; and “Edit” then “Duplicate” or Ctrl + D
3 - Group all rectangular shapes
4 - Draw elipse shape
5 - Select, from right to left (Left to right including entire shapes works the same way), both shapes (rectangles and elipse shapes)
6 - Use the boolean tool.
This is what I identified before providing the alternative approach of picking non-adjacent vertical shapes. I don’t know if this is a bug or not but it’s not the outcome I expected initially. It seems to me that LightBurn is possibly handling this as a weld operation or something similar.
Doing that the exterior line will not be a continuos line, and that it’s not what i pretend.
To me, it’s hard to believe that Lightburn can’t do it.
Just have to find the right way.
Can you elaborate on this? Are you expecting the exterior perimeter of the final shape to be a continuous line forming a single closed shape? If so, none of these approaches will accomplish that directly. But you’re starting with that shape so you could duplicate that to begin with.
If, however, you mean that you want all the individual pieces to form the appearance of a continuous shape then my approach still works.
Again, you need to do this in 2 stages. Once with half the vertical shapes, selecting every alternating shape. Then repeating this with the remaining alternating shapes.
This is what it will look like after the first stage:
What I’m trying to do is draw a line on paper that will later stiked to a plate sheet to be folded into 10 equal parts. In the end it will result in a tube with a certain shape at one end to match right with another tube where it will be joined.
My idea is that the outer line is a cut and the inner lines are dashed to keep the shape together and serve as a guide for where to make the folds.
I’m having some difficulty understanding your “strategy” but we’ll get there.
So if you want to know if [quote=“berainlb, post:10, topic:101324”]
Are you expecting the exterior perimeter of the final shape to be a continuous line forming a single closed shape?
[/quote] I say Yes
Well, I’m trying some methods to get there starting from the ideas you left.
I found a way to achive it, or at least very close.
Can you see this video I made?
It was not easy but finally i identify what I was doing wrong.
I was selecting vertical shapes and then draging the mouse until outline shape, so both shapes be selected. But this is not what you intend.
What you mean is, Select vertical shapes, then with Ctrl key pressed, select the outline shape.
This way I get what I pretend.
On this example we need to duplicate the outside shape. But in the project i am doing “duplicate” was not needed and the result is precisely what I pretend.
Yes, I agree with you but I even tried a second time before commenting…
In the example we are using is that what happens, but on my project don’t.
Maybe odd but for now I have a good solution!
