STEP assemblies: a link that closes a loop in the assembly is dropped, so no block inserts itself; the walk is iterative. Each imported block gets a name the drawing does not use yet instead of silently reusing an existing definition, inserts are pointed at the names the blocks got, and an insert of a block that could not be defined is left out with the error reported. Names that come from files (STEP products, 3D Studio objects, materials and cameras, WMF font faces) go through a new shared scene::sanitized_table_name, which applies the block-name rules (reserved and control characters, 255 characters). 3D Studio: meshes with more vertices than a polyface mesh can index are split over several meshes. Single-layer mode uses the current layer. Materials are only created when the drawing has a material dictionary. Camera views get the current view's proportions and the perspective flag. Messages show paths as given, the file-not-found and read-failure messages are plain text of our own, and the "Press Esc" line is gone since the import cannot be cancelled. The true-colour packing is shared. "Select ACIS File" and "Import WMF" get catalog entries and keys in all 22 locales. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
