Zooming operations can be invoked from the Scale toolbar.

To zoom in using mouse, press Ctrl + Shift, hold it and move the mouse with the left button pressed. Release the mouse button to stop zooming in / out. Having a mouse with the scrolling wheel, rotate the wheel to zoom in / out.

Rotation - press the left mouse button, hold it down and drag the mouse. Release the mouse button for scene repaint. (Rotation can be also performed using the cube on the Scale toolbar . Use the same method to rotate the cube. Once the mouse button is released, the scene is repainted in a new position.)

Selecting center of rotation - with Control button pressed, click the left mouse button on sheet or tool. The point clicked becomes the new center of rotation. Use Zoom Fit to move the center of rotation to the center of scene and window.

Panning - press the right mouse button, hold it down and drag the mouse. Release the mouse button for scene repaint.

T-SIM allows to display nodes with different boundary conditions using different colors. Also nodes in contact with different tools can be displayed. The following table shows node types displayed in T-SIM:

For information how to switch visualization of different nodes on and off, see Display options.

Using Scale toolbar, different profiles can be displayed on sheet:

• No profile - no profile displayed, grid basic color is used (see Display options)
• Thickness profile - thickness profile of the sheet.
• Temperature profile - temperature profile of the sheet
• Stress von Mises - von Mises stresses. The von Mises stress is computed from the principal stresses as follows: Sigma = SQRT({0.5[(P1-P2)^2 + (P2-P3)^2 +(P3-P1)^2 ]} SQRT refers to square root and ^ refers to the power.
• Extension in X - extensions in the direction of the X axis. It is defined as an extension of an infinitesimal abscise placed in the direction of X axis before thermoforming process started.
• Extension in Y - extensions in the direction of the Y axis It is defined as an extension of an infinitesimal abscise placed in the direction of Y-axis before thermoforming process started.
• Planar extension - planar extension profile. Planar extension is an average extension expressed by extensions in principal direction:
  lambda planar = SQRT ( lambda1 * lambda2)
  SQRT refers to square root.
• L1 / L2 - ratio of relative extensions in two principal directions (1 and 2)
  L1/L2 = 1 means deformation is equibiaxial.
  L1/L2 >> 1 means deformation is almost uniaxial.

For every displayed profile, its limits can be set using Scale limits dialog.

To set limits for displayed sheet profile, click on Limits button on Scale toolbar. The following dialog appears:

Select Automatic or Fixed.
When Fixed is selected, the scale is kept fixed with limits specified in Min. and Max. value.
When Automatic is selected, T-SIM calculates minimum and maximum on the sheet and uses these values as minimum and maximum for the scale.
Click OK to confirm changes.

Remark: Scale limits can be specified for any profile (thickness, temperature, stress, extensions...).

The automatic mouse position tracking enables to display information about nodes / elements / 3D points in the location where the mouse points.

To switch on the automatic mouse tracking, use T-SIM messages bar - check the small button with the following icon (the icon tool tip is "Item info on / off"):

Now, move the mouse cursor to point on sheet or tool. On the T-SIM messages bar, information about the node / element / 3D point under the mouse cursor is displayed:

The type of information displayed depends on the item under cursor (sheet or tool), and also on the Tracking & Shift + RBtn (Right mouse button) function selected in the Scale toolbar:

Click on the combo box with title "Shift + Right mouse button function" and select one of the possible functions.

• 3D Point Info - display 3D coordinates of the point under the mouse cursor
