Changes in 23.1.2 (compared to 23.0.7)

Key known issues

• Note: when you load old files in 23.1.2, please first check CAD's mesh: you may want to remesh the part with larger mesh size (if there are too many too small triangles). (In older Artist Studio CAD might be coarse by accident. From 23.1.2 we follow user's choices, but this may lead to much more detailed mesh than what was accidentally used before, leading to algorithms being slower than needed.)

• If this happens you will get a dialog encouraging you to check the mesh and to save the file afterwards.

• [CEV-3291] When applying the parallel offset on closed curves, the orientation of the master curve and the slave curves might be in opposite directions. (To overcome this issue, simply select the master curve and reverse it.)

Main changes

• [CEV-2764] Patch based "ply book" - first implementation
• [CEV-3313] Improved ply book (also visible in machine data, added icons to the ribbon etc.)
• [CEV-3198] ACoSaLUS/VisCheck: Definition of camera angles for Patch Placement Inspection
• [CEV-3278] ACoSaLUS/VisCheck: Motion Artist support for Patch Placement Inspection
• [CEV-3434] ACoSaLUS/VisCheck: Placement inspection movement can have rotated orientation
• [CEV-1599] Logging to files with spdlog
• [CEV-3456] Improved logging to a log file
• [CEV-3285] Improvements and clean up of Overlap lengths calculation and visualization
• [CEV-3151] Mesh gets reset in many situations (selection in GUI, saving, assiging tool to MA)
• [CEV-3452] Rolling motion: gripper preview not solid
• [CEV-3480] Remeshing is performed when Thickness color plot is applied
• [CEV-3315] Use express mesher for robot model objects Robot Model
• [CEV-3329] Automatically clean-up temp folder
• [CEV-3295] keys.xml load only on startup: use JS "as.refresh_config();" if you need to update/reload keys.xml while Artist Studio is running
• [CEV-3440] Make loading responsive during loading, and speed up loading of legacy files

Patch Artist

• [CEV-3300] Weird draped patches in customer file
• [CEV-1826] Remesh not performed with default meshing parameters
• [CEV-2551] Support multiple sublayers for "master only" slave curve definition
• [CEV-1730] Move patch: undo does not check if patchPreview is empty
• [CEV-1733] Move patch: extra undoSteps via keyboard when no patch selected
• [CEV-3267] Move patch: stuck, no way to accept or cancel
• [CEV-1665] Crash on multiselect during patch movement

New parallel offset algorithm

• [CEV-3396] New parallel offsets: Enable beta parallel offset for everyone
• [CEV-3333] New parallel offsets: If beta parallel offsets are enabled, loaded files are still converted to old parallel offsets
• [CEV-3043] New parallel offsets: Directed master curve projection
• [CEV-3049] New parallel offsets: Master curve tracing skips sections
• [CEV-3181] New parallel offsets: Slave curves' curveIndex (not id) has the wrong sign - beta parallel alg (this means that overlap optimization works now too)
• [CEV-3457] New parallel offsets: AS crashes when creating curves with the BETA parallel AND trim edges at turning point activated

Motion Artist

• [CEV-3210] 2D machine dataset properties not shown

Motion Artist - specific production cells

• [CEV-3232] Use trapezoids writer and support rotational axis export in SAMBA PV

• [CEV-3421] Create gripper files for SAMBA PV system
• [CEV-3486] Customer cell: Update SAMBA Step cell to correct axis limits
• [CEV-3551] Deposit frame E1 ignored on certain patches (SAMBA Step L)

Trapezoid patches

• [CEV-3418] Use nominal patch length/width in xml export (instead of bounding-box length/width)

FEA

• [CEV-3307] PCOMPG creation doesn't take overlaps inside same ply correctly into account
• [CEV-3301] FEA Export settings give wrong fiber orientation for whole ply when using PCOMPG format

• [CEV-3341] Reversed layup from FEA export
• [CEV-3299] Crash when performing Nastran FE export

Import/export

User interface

• [CEV-3207] Patch type selection impossible
• [CEV-3252] "Set position" dialog in Machine configs: pressing enter during editing one field resets all values to default

Saving and loading

• [CEV-3500] FPP with the specific CAD tool name can't be saved second time (UTF8)
• [CEV-3528] FPP with the specific CAD tool name can't be saved second time (special characters)
• [CEV-3282] Analyze file saving and loading duration
• [CEV-3297] Reduce file loading time

Variable patch length

• [CEV-3052] Crash in curve discretization (patch creation) for VPL / TO
• [CEV-3103] Crash while recreating patches using VPL discrete

Other fixes

• [CEV-3309] Crash while opening file in empty AS window
