Unskilled coder trying to find out if something is even possible

Valandar

So... I'm sitting here, with almost 200 files to repair for 3D printing (99.9% of the issues are solved by 'cap holes'), and need to have both obj and stl versions.

Is there any way to create a script for 3DS Max that will read in an obj, add a "cap holes" modifier, collapse the stack, re-export under the original file name, and then export again as an STL, then delete it from the scene and load in the next obj in the directory, eventually doing this to every obj file in the directory? And if there is, what resources would I use to create this script?

copy this into a new script, change the directory text to the directory you want process  and press ctrl-e

(<br>&nbsp;&nbsp;&nbsp; fn getFilesRecursive root pattern =<br>&nbsp;&nbsp;&nbsp; (<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; thedirs = #(root + "/*");<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; join thedirs (GetDirectories (root+"/*"))<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; for d in thedirs do join thedirs (GetDirectories (d+"/*"));<br><br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; thefiles = #();<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; for f in thedirs do join thefiles (getFiles (f + pattern));<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; thefiles;<br>&nbsp;&nbsp;&nbsp; )<br><br>&nbsp;&nbsp;&nbsp; fn processfile filename = if getFilenameType filename == ".obj" do<br>&nbsp;&nbsp;&nbsp; (&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; resetMaxFile&nbsp; #noPrompt;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; importFile filename #noPrompt using:ObjImp;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; setCommandPanelTaskMode mode:#modify; -- addmodtoselection needs this to work<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; select objects;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; modPanel.addModToSelection (Cap_Holes()); -- cap the holes<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; convertToMesh objects; -- collapse the stack<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; exportFile filename #noPrompt using:ObjExp -- overwrite the original and export as stl<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; stlfilename = (getFilenamePath filename) + (getFilenameFile filename) + ".stl";<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; exportFile stlfilename #noPrompt using:STL_Export; <br>&nbsp;&nbsp;&nbsp; )<br><br>&nbsp;&nbsp;&nbsp; FilesToProcess = getFilesRecursive "c:\\Temp" "*.obj"; -- change to the directory you want to process<br>&nbsp;&nbsp;&nbsp; for f in FilesToProcess do processfile f;<br>)

backup first this hasn't been tested to any extent so we take no responsibility for what happens next

Backup the directory, I assume... and thank you very much!

Now... can you explain why this works? The last time I did any coding was in Pascal, back in spring of 1987...

EDIT: Okay, I tried it, and it converted 35 out of roughly 200 then stopped. Aaaah.... apparantly it doesn't read if the OBJ has its extension in all capitals. Bulk Renamer, here I come!

EDIT EDIT: It worked! Thank you very much! That was who knows how much drudgery avoided.

no probs

first it collects (including sub directs) from the root dir all the file names with the filetype ",obj" into an array. I then iterates through each filename and processes that filename. The processing is as follows

reset Max

import the obj file using the filename

set the command panel to modify

select all the objects

apply a cap holes modifier to them

collapse the stacks

export as obj

export as stl
