[Plugin] Slicer v4.3 20110619

TIG

You can make a 'curve' from any selection of edges that are continuous - use 'weld.rb'.
You could set this curve in 4" from the face and then a rib 10" wide inwards from that.
Centers would then be the curve's nodes ?
Height matches the face's height where it is 'cut'.

mariocha

Yes that is just right.
(I confused "curve" (arc) with "curve" (polyline))

mariocha

Following your advice in an earlier post about using JPP, I looked at it again. I realized I was not using the settings adequately. Once the settings are right, it does the job pretty well.
All that's needed now is Slicer to follow the curve of the footing slicing at angles like you mentionned.

mariocha

Well, for now, the ribs are perpendicular to a straight line averaging the direction of the pane. This line angles as needed and we treat the mesh in sections. I ajust the axis along the way. We have to do a footing plate showing where to stand the constructed rib.

Firstly great work on Slicer, but as many have mentioned an upgrade to slicer-modeller would be fantastic. I have also started learning paracloud gem, but as of yet there aren't enough reasons for me to go out and buy it just right now. Although I don't fully understand all its functions yet, I was particularly interested in a ribbed structure in their gallery which was created by some sort of internal 'pinch' points. It is illustrated below..

Could the slices perhaps follow bezier curves either (A) - manually created by the user, or (B )- generated automatically by some sort of 'pinching'?

Possible??

TIG

Look at my Extrude Edges By Rails By Faces
Make the face a 'rib' ?
OR try the simpler EEbyFace and process a 'rib' face just the one curve at a time, useful if the form is not susceptible to a 'meshed' solution...

princedragoncok

Yes that is almost the solution indeed... but what about the slots? Can slots automatically be made at intersections via a plugin? and then laid out nicely like in slicer?

mariocha

One could also try FFD on the grouped slices. No ?

TIG

You want "Slotter"

Run the 'Slotter' tool, you select a shape [group] that has some intersecting forms [groups] (perhaps two 'sliced' sets in two 'planes'), choose whether 'top' or 'bottom' slots required in the selected shape.
It booleans half slots in the selected shape at every intersection [say from the 'top] to match the intersecting forms, and also all of the other forms gets slots added in the other direction, so that then all of the forms will 'slot together' if made in reality...
The slotted shapes would be copied/grouped for safety and laid flat if desired ?

This idea is quite doable... I'll think on it

Any feedback welcome during the 'gestation' phase...

princedragoncok

Slotter... that's exactly it. Don't really know what to add to your description at the moment apart from laying them out neatly after slotting. I have a laser cutter at my disposal at the moment (I work in a model shop) and would love to realise some concept designs with slotter, slicer and slicermodeller. Looking forward to the next upgrade!

wtf
we need a smiley of someone tapping there watch.

[edit] guess this will have to do

TIG

I do the impossible immediately, but miracles take a little longer...

Lol, a slicing miracle... I can't wait

@tig said:

If you made a curve along the front edge then the ribs could be angled to match the angle-bisector to each pair of edges at a node, or square at the ends ?

I just encountered a situation where I am asked for ribs that follow the curve, staying perpendicular to it (like radial).

TIG

Noted...

I have a [privately written and hopefully paid for] 'Slicer v4' that has such lines added etc for CNC work - watch this space.

hey, are you finally going to make your own and bust that slicemodeler @&&hole

I have written a paid commercial version [private] - Slicer_v4 - for someone for CNC use etc... it [or some of its ideas] might leak out to you too...

any news?

TIG

The news is, no news... I am bogged down with other 'paid stuff' at the moment... BUT it is around 2nd on the list [after some big stuff]

TIG

Here is v3.0 of Slicer.rb.

You can now choose / make its Layer on the fly and select any 'Colour'...

Enjoy...

(see v. 3.1 here instead)

I am working on a 3D printer so i was thrilled when i found you program. I just wonder if there is a way to save each slice individually?
thanks foe a great program.

I've a new version of Slicer on the back-burner that actually makes the slices as components.
Meanwhile this code snippet will do something for you.
First it converts the slice-groups to component-instances and then it saves them separately as SKPs in a folder called 'Slices' with the Model, each named after "model-name_slice-name.skp"...

def slicerexporter()
  mod=Sketchup.active_model
  pat=mod.path
  (UI.messagebox("Save Model First!");return nil) if pat==''
  sel=mod.selection ### process selection
  gps=[]; sel.each{|e|gps << e if e.class==Sketchup;;Group}
  (UI.messagebox("No Groups Selected!");return nil) if not gps[0]
  fol=File.dirname(pat)
  mna=mod.title
  sfo=File.join(fol,"Slices")
  Dir.mkdir(sfo) if not File.exist?(sfo)
  mod.start_operation("slicerexporter")
  puts "Saving SKPs...\n" 
  gps.each{|grp|
    sleep(1.0)
    nam=grp.name
    ins=grp.to_component
    dfn=ins.definition
    dfn.name=nam
    pat=File.join(sfo, mna+"_"+nam+".skp")
    dfn.save_as(pat)
    puts pat.tr("\\","/")
  }
  sleep(1.0)
  mod.commit_operation ### one step undo group >> compo = 'groups' reverted
  puts "\nDone."
  UI.openURL("file;///"+sfo)
  ### NOTE; Sometimes these SKPs CAN be corruped on save_as ;(
end

Copy+Pase into a file called slicerexporter.rb in Plugins - it should auto-load...
select Slices then in Ruby Console type slicerexporter and watch messages...
