DeleteDoubleFaces

SHORT DESCRIPTION

HOW DOES IT WORK?

FEATURES

This version removes support for MAX 2 and 3 and the Quick Check option, but accelerates the overall performance significantly.
Note that the script is now a MacroScript with a floating dialog - evaluate and customize from "Bobo_s Tools" category.
Tested in 3ds Max 2010.

This version includes a fix for MAX 4. No other changes, should work in R3 and earlier, too.

This version includes explicit check for MAX version.
Version 3.3 relied on an error trapping code and failed to work with MAX 3 correctly.

This version makes DDF compatible with 3D Studio MAX R3.
The same version remains compatible with R2.x, but I encourage
R2.x users to keep on using version 3.01
No new functions have been implemented.

Version 3.01  (11/10/98)

• Select any number of Meshes.
• Press the [CHECK Selected Meshes] button to search for DoubleFaces.
• By default, the "Quick Check" checkbox is active. This will let the utility use an "exact match" - for example, it will detect two faces using vertices [1,2,3], but not faces using [1,2,3] and [3,2,1].
• If you deactivate the "Quick Chek" checkbox, every face will be checked for duplicates with any vertex order (and flipped normal). This option is much slower, but more precise.
• The [EXTRACT DoubleFaces] checkbutton lets you create a copy of all faces that will be deleted as duplicates. This way you will have a "trash bin" version of the deleted faces with all their properties (except VertexColor). The new mesh will have the same name with a "DF_" prefix, will have the same material, and will keep the Mat.IDs, Edge Visibilities, Smoothing Groups, and Texture Coordinates.
• Check the [DELETE DoubleFaces] checkbutton to delete the detected faces. They will be selected using MeshSelect, and deleted by a "DeleteMesh" modifier. You can use the MAX's Undo butons or remove the Modifiers by hand if you want to restore the original state.
• The Radio buttons let you alter the way the Deletion works. If you select the second option "Collapse EMeshes only", the Modifier Stack of Emeshes that used to have NO MODIFIERS will be collapsed. This way you end up with EMeshes with reduced face count and the same modifier stack state as before. Meshes with modifiers on the stack will receive the Select/Delete Modifiers and will not be collapsed. You can Undo the changes on per-object basis.
• If you select the third option "Collapse All Meshes", the Modifier Stack of ALL MESHES will be collapsed, no matter how many modifiers they used to have initially. You can Undo the changes on per-object basis.

BUGS REPORT:

• Version 3.01 Fix: All older versions seem to cause an Unknown System Exception under R2. V 3.01 fixes this by working with EditableMeshes ONLY (Primitives and any other objects will not be checked). I know the source of the problem, but not the reason :o( Anyway, this version should work ok with all MAX R2.x releases.
• Version 1.13 Changes: lots of labels and text changed.
• Version 1.13 Fix: with Precise check in older versions, tripple and more faces have been detected, but just the first face got selected.
• Version 1.13 Fix: The message box about Modifiers present appeared randomly, since the value checked was retrieved AFTER the check :o( Stupid me!
• Version 1.12 fixes a typo-bug in the Precise check mode. Once again, sorry for the bugs :o)
• I got reports about MatIDs getting corrupted when using DDF, and even about MAX crashing, system freezing etc.. I could't recreate any of these disasters. Please let me know if you find any troubles with the script!
• Version 1.1 fixes a bug with the Precise check mode (Quick Check OFF) which did what the STL-Check usually does... :o) Now, the first faces encountered remain in the mesh, every duplicate that follows gets deleted.
• Version 1.1 added a message box when modifiers are present on the mesh - 1.0 crashed when trying to delete faces permanently from a modified Emesh.
