Clashes... any such plugin?

baz

I just had to redraw 3 bathroom vanities because we could only get 19mm sheets instead of the 16mm we wanted.

So I start to modify the 3 cabinets to expedite for my very accurate cutlist.
Was thinking one hour... but four hours of cursing later...

The thing that took the time was resolving the 'clashes'. I had front/side views set up with background line, so I could see exactly what was happening. But so many components were not lined up after my 3mm increase of thickness. And then it was very difficult to get to a view where i could 'see' & fix the problem.

Then watching tv i saw a show on engineering where they had several 'Clashes', A term I hadn't come across before.

"Clash:
Refers to one building component physically yet unintentionally
penetrating another building component; (there could be more), that is,
components competing for the same physical space."

Is there any way a plugin could identify groups/comps that penetrate or 'Clash'?
And isolate them for intervention in some manner?

Building wise you can check for clashes with Trimble's Tekla Bimsight wich accepts sketchup models and is free.

JQL, have you tried it? Do you know how does it work in practice?

pbacot

Also referred to as "conflicts", right? Seems based on components and groups a plugin could do it?

Check for over-lap of given component removes one

same thing plus many other tools related to solids

I did import a model into it, but I've never delved deeply into it.

I do know what it does though...

Insert a model of your project;

Insert a model of your project structures or of any other of your consultant's projects.

Check where one model interferes with the other, measure the model, produce visualizations from it and create a database with revisions.

How far can you go with it I don't know but it's supposedly something that a Contractor or the Promoter can use to follow up on the project and construction.

mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
sel.empty? ? ents=ent.to_a ; ents=sel.to_a
grp = ents.grep(Sketchup;;Group); sel.clear
for i in 0...grp.length-1
  bounds1 = [grp[i].bounds.min.to_a,grp[i].bounds.max.to_a]
  for j in i+1...grp.length
    # bb=grp[i].bounds.intersect(grp[j].bounds)
    bounds2 = [grp[j].bounds.min.to_a,grp[j].bounds.max.to_a]
    intersectBounds = [[0,0,0],[0,0,0]]
    validBounds = true
    (0..2).each do |index|
      if(bounds1[1][index] <= bounds2[1][index])
        intersectBounds[1][index] = bounds1[1][index]
      else
        intersectBounds[1][index] = bounds2[1][index]
      end

      if(bounds1[0][index] >= bounds2[0][index])
        intersectBounds[0][index] = bounds1[0][index]
      else
        intersectBounds[0][index] = bounds2[0][index]
      end

      if(intersectBounds[0][index] > intersectBounds[1][index])
        validBounds = false
      end
    end
    if validBounds
      puts "#{grp[i].name} and #{grp[j].name} intersect"
      sel.add grp[i],grp[j]
    end
  end
end

Checks all components for "clashes". Adds both components to the selection when overlap or contact is found.

Wow, thanks sdmitch. Now I have to figure out how to use the ruby console I usually stay well away from it.

glro

this code detects clashes of parallelepipedic volumes, when the bounding box of the object and the object, are in the same volume

if the objects are not parallelepipedics, you might have false positives

@baz, can you post an example model, before the sheet thickness change...

How it's made will dictate if a 'intersect with model' can be used to make life easier...

Unfortunately this is true given the way Sketchup defines bounding boxes.

To use, copy and paste into Ruby Console window and press Enter.

If you have used components properly [flipped copies etc...]
and are prepared to pre paint faces to be adjusted...
a plugin can adjust the material thickness and the 'clashing' edges...

here's a test..
like this...

pbacot

SU "knows" when faces intersect--wouldn't that be a better indicator for this analysis?

driven

Peter, you can use intersect to find them, but SU won't know in which direction or which faces to move...

it's a bit like Solid Tools and would need many options for a semi-automated result...

You would also need to manually thicken everything first...

with cabinetry, it's easier if you use a material only on the items to adjust, then let ruby run using pushpull, when done you can repaint if needed...

it would not be too hard to wrap my code as a plugin...

I was thinking of the general use where you want to see if a duct is intersecting a beam. You'd just want the tool to show you where so you can fix it yourself.
