VTube Update History 4.2 - February 2024

Version 4.2.1454, February 9, 2024

User warnings were added for three conditions in SB calculations.

1. All the NOMINAL BEND ANGLE VALUES are nearly identical in this part. (The threshold is 5 degrees.)
   Only the PROPORTIONAL ANGLE springback will be calculated. The FIXED ANGLE springback will be zero.
   For a more realistic springback setup, use a part with at least two different bend angles.
   
   
2. The NOMINAL BEND ANGLE VALUES are too close to ZERO. (The threshold is 0.1 degrees.)
   VTube cannot calculate springback variables when bends are this small.
   
   
3. There is only ONE NOMINAL BEND ANGLE in this part.
   Only the PROPORTIONAL ANGLE springback will be calculated. The FIXED ANGLE springback will be zero.
   For a more realistic springback setup, use a part with at least two different bend angles.

Version 4.2.1451, February 6, 2024

Springback table search features were added.

Version 4.2.1450, February 5, 2024

New Springback optimizations were added.

1 - A new Part Setup popup option will add a new row to the Springback table and then transfer the current Material, Springback, and Elongation variables to that row.

2 - Multiselect delete is now available in the Springback Table (ST).

3 - A new "Copy from Part Setup All" button is added to ST

4 - New UI direction arrows help users know what direction data flows in ST.

Also, see the new tutorial video on Vimeo:

Version 4.2.1448, February 3, 2024

VTube-STEP and VTube-LASER now use color-coded arrows pointing to the Part Setup springback values immediately after the values are calculated.

1. A blue arrow indicates that the MEASURED tube data was used to calculate the springback variables.
2. An orange arrow indicates that the COMPENSATED tube data was used to calculate the springback variables.
3. A green arrow indicates that the OVERBEND calculator was used to calculate the springback variables.
4. The arrows disappear after 15 seconds.
5. Click on the arrows to make them disappear before 15 seconds.
6. The arrows are floating windows that do not interfere with the VTube user interface.

Version 4.2.1446, February 2, 2024

1 - The positioning of floating control windows was fixed to display on the correct side of the screen for any multi-screen setup.

2 - A new Springback menu for springback calculation from measured data was added to the Measured Tube menu.

3- A new Springback calculation button for springback calculation from compensated data was added to the Bend Setup Springback menu.

4 - VTube-STEP has improved memory handling for calculating parametric data from collected cylinder entities.

• We added this logic for models with a high bend count (anything > 50).
• A new option in the Graphics menu in System Options allows the surface data to be cleared immediately after the tube centerline is calculated.
• In our tests, this saved about 1 megabyte per straight calculated.
• This logic also reduces the size of the project files because surface data is stored in project files.
