RE: [Plugin] Import ALL from Folder

You code is overly complicated.
It also has some odd working practices...I am sure I have answered this same query elsewhere...
See the @yuyuwhy posts...
Is it you, but with a different user-name ??
http://sketchucation.com/forums/viewtopic.php?p=554042#p554042This thread explains how to setup an empty model SKP - the order of purging IS important - yours is wrong !
Do that BEFORE importing anything.It also suggests a sensible approach to the subsequent import, purge and export of each DAE in turn.
If you enclose those actions within a 'model.start_operation(...)
' block, BUT afterward each you 'model.abort_operation
' it [NOT the usual 'model.commit_operation
' it] then the imported data is simply forgotten, but the export is safe because the DAE file is now outside of the SKP's control... So there is no need to purge between each import/export at all.Recast your code thus...
Make the host SKP empty.
Process the list of DAE files in turn.
Use amodel.start_operation(...)
block around each iterate step.
Remember to use themodel.abort_operation
to undo the import etc, but leave the export intact.
You should end up with an empty SKP and all of the DAE files processed.Incidentally, your code only works in v2015 as the UI folder selector is new in that version's API.
Thanks!! I tried and it works!
And I want to import *.dae file with 2000 jpg.However Sketchup stop at 10%. It do not warn me anything.

RE: [Plugin] Import ALL from Folder
@driven said:
I only use mac, but...
you could, save each file to 'Trash', close it, then open a new for the next import?
SU should then be starting fresh each time and you don't need to erase any entities?
just a thought, I use the idea in a script...
this is the an extract for Trash on a mac...def revert > trash_copy = (File.expand_path("~/.Trash/" + "." + @orig.title + ".skp")).dup.freeze > @orig.save(trash_copy) > Sketchup.send_action("closeDocument;") > Sketchup.send_action("newDocument;") > end

I tried it.It works fine on my PC,however it crashed on others. -
RE: [Plugin] Import ALL from Folder
@tig said:
You said 'ade', I guess you really meant '.DAE' ?
They should import OK.
Any error messages in the Ruby Console when try it ??Yes! I mean *.dae files.
I use your script.and add purge_unsed,export.
However i need to handle thousands of files.Sketchup always crashes after export few files.
I really don't know how to fix it.
any helps?

Sketchup crashes when import,purge_unused,export dae files
Sketchup crashes when import,purge_unused,export hundreds of *.dae files.
I use api to do this.It works fine while handling few *.dae files.
anyone konws why?Here is my code

...I'd like to add an optionnal STAGE in your script.
Once a file is imported, i'd like to create a new layer named by reference to the file name with a suffix.
Let's say Wonka_Niv1
Then, Group all the freshly imported items on this new layer.
Then proceed to the next file...What file type are you importing?
SKP and Others need to be treated differently...
Obviously none of this 'Layering' stuff will ever work with imported 'Images' !!For non-SKP files:
Provided there is at least one object already in the receiving-SKP, then all imported formats [other than a SKP] will already import as a component named after the file - e.g. "Wonka_Niv1.dwg".
So after line#84:
model.import(file,false)
add these lines:
unless File.extname(list[0]).downcase==".skp" ins=model.definitions[File.basename(file)].instances[0] ins.layer=model.layers.add(File.basename(file, ".*")) end#if
Note: this uses the imported files 'basename' [e.g. "Wonka_Niv1"], to use the full name with say its '.dwg. suffix use...add(File.basename(file))
insteadFor SKP imports you will need to edit another part of the code:
after line#107:
ins=model.active_entities.add_instance(defn,tr)
add this:
ins.layer=model.layers.add(name)
This uses the imported SKP's name, without any '.skp' suffix [e.g. "Wonka_Niv1"] - but if you want to add one, then change...add(name)
to...add(File.basename(file))
This should do what you want...
after i use this plugins to add ade files,i can not see them!
i can not understand why.
any helps? -

If the face[s] and the rectangle that won't 'cut' are indeed coplanar select them both and "Intersect" them. they will now break... [it works I tried it...

Edge cann't split a face to two faces
i use extrudeEdgesByVectorToObject to extend.but i expolde all groups and edge is within the face ,because i use point_in_polygon_2D to test it.however it cann't split a face to two faces.
and i draw this edge by hand ,it will split.

RE: How to get face which is belong to two group
@tig said:
Get
tr1=group1.transformation > tr2=group2.transformation
You need those th apply to things later...
The two 'coincident' faces in question will have some similar properties [when adjusted for their container's transformation].
You need to iterate the faces in group1 to get a suitable in group2faces1=group1.entities.grep(Sketchup;;Face) > faces2=group2.entities.grep(Sketchup;;Face) > face2=nil > face1=nil > faces1.each{|face| > min=face.bounds.min.transform(tr1) > max=face.bounds.max.transform(tr1) > norm=face.normal.max.transform(tr1) > faces2.each{|f| > if f.bounds.min.transform(tr2)==min && f.bounds.max.transform(tr2)==max && f.normal.transform(tr2)==norm.reverse > face2=f > face1=face > break > end > } > break if face2 > } > ### face2 is the matching face in group2, if not nil ! Delete it ! > ### face1 is the matching face in group1
This is NOT foolproof.
BUT you can add extra tests...
For example... collect the loops of face2, collect their vertices as points and transform them, then compare with the loop-vertices-points-transformed of face1, if there are any mismatches then the two faces are NOT completely coincident - e.g. one of the otherwise coincident could have a side-notch or a hole in it, but still have the same normal and bounds !
You need to make these decisions... Simple boxes ?one more question.if there are many groups,how can i get the groupA which is adjacent with groupB.
i intend to judge by distance.is there any easy way to do this? -

RE: How to get face which is belong to two group
@cotty said:
If there is one face (in one of the groups) or if there are two faces (one in each group) depends on the way you created the groups. You can always enter one group, copy the face to the clipboard and paste (in place) it outside those groups to get a single face independent of the groups.
i think i don't explain it clearly. there are two faces (one in each group),as you say. and when i explode two groups,i can get 11 faces which 1 face is delete.
i wanna use api to get this face in groupA which in groupB also has this face .i mean they are occupy same region.but they are different.
can i do it by judge face's vertices position or some other ways? -
How to get face which is belong to two group
there are two groups .i wanna to get the face ,which is belong to two groups.just like two walls,there is a face which can be think to belong any wall.
as the picture.
how can i can get the face?
thanks

How should i judge points can construct face or not

any helps? thanks!!

How shoulid i to extend with more than 4 edges
just like the pictures.
the face has 6 edges.and i want to extend it to fill up the gap with the top faces.
the problem is there are 3 faces ,and i need to extend the face to them ,make sure there are no gaps any mnore.is there any plugins to do this ?
thanks for help!

RE: Is there a way to judge a edge is through face or not?
@tig said:
Simple way.
Get the 'vector
' from the center-point [point1
] to the other external-point [point2
].
vector = point1.vector_to(point2)
Now do a 'raytest
': using...
raytest = Sketchup.active_model.raytest([point1, vector])
The 'raytest
' will benil
if nothing is hit, BUT since you say there is always geometry surroundingpoint1
that should never occur.
So it succeeds and returns an array with two elements:raytest[0]
is thepoint
of intersection and the second element,raytest[1]
is an array: that array contains the 'hits' in nested order - with any geometry listed last.
So the last itemraytest[1][-1]
is a reference to the 'face' that is intersected.
Note that it might be an 'edge' if the points and geometry are such that the 'ray' passes through the intersection of two or more faces.
Other elements in that array [if any] represent the 'container' references - like group or component if applicable - these are in nested order...thanks.it works.

RE: Is there a way to judge a edge is through face or not?
@dave r said:
As I already asked, why do you need a plugin to see if the edge passes through the face?
Maybe you could explain what you really need to do.
i have a cube . and i konw the center of the cube ,and a point outside the cube. connect this two point , i want to konw which face will be through?

Probably not but would be easy enough to create one. How would want it to work?
