Configure global START-PROF application settings in this dialog

General Settings

Property

Description

UNDO steps

Number of actions available for undo/redo. Higher values require more memory. Set to zero for large models to disable UNDO and improve performance.

Use OpenGL emulation

Enable for software-based 3D rendering. Disable for hardware-accelerated 3D graphics. Use emulation only if experiencing 3D view issues - performance will be slower.

Create backup files

Create two backup copies when enabled: project_name.bak0 and project_name.bak.

.bak0 creates when loading a project. .bak saves input and output data before last save.

Files save to folder defined in General Settings > Paths to Files > Temp Files

Add Time stamp

Create backup copies with date/time stamps: "~20-05-09(14-50).bak"

Files save to folder defined in General Settings > Paths to Files > Temp Files

Interface style

User interface visual theme

Panel docking mode

Floating window docking behavior

Always show full menu

Display complete START-PROF menus (not just frequently used commands)

File actions before analysis

Behavior before analysis

  • Always save - Save file before analysis

  • Never save - Do not save before analysis

  • Always ask - Prompt to save before analysis

Autosave

Create automatic backup copies at specified intervals. Configure interval in settings.
Files save to folder specified in Settings > Paths to Files > Temp Files. Automatic file naming, e.g., AECDEEEEA85247c3941E4E16375DF808.<project_name>.ctp. Temporary files delete on proper START-PROF shutdown

When "Same as data file" selected but file never saved, copies save to:

C:\Users\<username>\AppData\Local\Temp\D5F756EDD5594dd88622F52E5FF84E73.CTAPT1.ctp

Check for updates

Enable automatic update checking

Rotation type

3D model rotation in 3D view. "Spherical" - standard rotation (versions up to 4.62). "Cylindrical" - rotation around vertical Z-axis.

User Interface

Property

Description

Show nodes and names in output

Display nodes and names when printing or exporting to Word

Delete invalid results

Automatically delete analysis results when integrity checks fail

Max error/warning rows

Limit messages in Error and Warning window. Set to 0 for unlimited. Recommended: 50-100 for large models to improve performance

Maximum Width of the column with the name

Prevents result tables from becoming too wide by truncating long element names. A value of 0 disables truncation and allows for unlimited column width

Maximum Number of pipes for updating the project tree

The project tree updates automatically if the model contains fewer sections than this limit. Setting the value to 0 disables auto-refresh

Max database rows

Default database display shows 100 rows. Adjust as needed

Pipe/Fitting Database Filter

Filter databases by standard. Example: "ASME" shows only ASME-compliant components

Default PUR insulation

Default pre-insulated pipe manufacturer for new projects. Override in project settings

Diameter selection tolerance

Matching tolerance for diameters from pipe and fitting databases

Thickness selection tolerance

Matching tolerance for wall thickness from pipe and fitting databases

Zero projections for new pipes

New pipe elements inherit DX,DY,DZ from previous pipe. Enable to start with zero values

Show all modes in results

Enable "Show all modes" checkbox by default in output
