Basic Concepts

This topic provides some interface concepts related to the Imagine & Shape app.

This page discusses:

General Principles

This topic provides the general principles you need when using the app.

Remote Control

  • The entire screen reacts to selections and manipulations.
  • Elements and handles can be remote-activated: the pointer does not need to be over an the element or very close to interact. The element that is closest to the pointer is selected. For elements such as faces or edges, the selection point is their barycenter. This gives you a real productivity gain and a very fast interaction with elements and handles.
  • Using a trap as a selection means is advised. Press Shift and drag to draw the trap. As a combination, you can press Ctrl to add or remove elements to the selection. Elements are selected if their barycenter is included in the trap.

  • To manipulate and deform a curve or a surface, it is advised to double-click the curve or surface rather than clicking.

Escape Key

Use the Escape (Esc) key to exit a command.

Smart Selection

When selecting a feature and launching any command, all the parent features (subdivision surfaces or styling curves) are temporarily highlighted to enable an easy selection. The selected feature is also temporarily hidden.

Positioning of the created geometry

When an element (point, line, plane) is already selected before entering a command, it is used to define the position and orientation of the created primitive.

Thus,

  • One point defines the barycenter.
  • Two points define the main axis and the middle of the points define the barycenter.
  • Three points define a plane and the normal to the plane defines the main axis.
  • A line defines the main axis and its origin defines the barycenter.
  • A plane's origin defines the barycenter and the normal to the plane defines the main axis.

V-Nav

You can use V-Nav to do the following manipulations:

  • Select a plane:

  • Rotate in the 3D area:

Fast Manipulation

When modifying an object, you can manipulate the nearest element to the pointer without selecting it.

From the Tools Palette, you can select Manipulator On/Off . The robot's display becomes smaller and is placed on the nearest element to be manipulated. It is no longer displayed on the barycenter of the selected elements, even in case of multi-selection.

Handle Representation

Here is the representation of the handle during a modification, for example while performing a rotation:

Plane not selected

Plane selected

The semi-transparent zone represents the planes of the handle. It can be hidden by the subdivision surface if it is put behind.

Step by Step Modification

This capability is available with the Translation, Rotation, Local Normals and Mesh Lines commands.

To select the elements to be manipulated, press Ctrl and move the pointer to automatically compute the step. By default, the step corresponds to a power of 10 or 5° for the rotation.

Tip: If you move the elements and then you press Ctrl, the step will be computed depending on the first displacement value.

Robot

You can manipulate (move and rotate) the subdivision surfaces and styling curves using the Robot. These capabilities work exactly as in the basic interface command, therefore this section of the documentation actually links the 3DEXPERIENCE Native Apps User's Guide. Note that the information detailed in this section is presented in an Infrastructure environment different from the Imagine & Shape environment (symbols, background color, for example).

Recommenced Guidelines

This topic gives you some advice when using the app. You are advised to:

  • Add a geometrical set and create the styling surfaces within this geometrical set.
  • Create two other geometrical sets for operations and for operations results.
  • Apply a pre-defined material on a subdivision surface.
  • Verify that the Material option is selected in the View > Render Style > Customize View command to visualize the mapping analysis on the surface.
  • Set the discretization option proportionally to the element size: in Me > Preferences > General > Display > Performance, set the 3D Accuracy > Proportional option to 0.1.
  • Activate anti-aliasing in Me > Preferences > General > Display > Visualization, select the anti-aliasing for Edges/Lines option.
  • Set the line thickness 2 to 1 (instead of 2 by default): in Me > Preferences > General > Display > Thickness and Font, set the Size in pixel for Thickness 2 to 1.
  • Select 1 for the Type in the Me > Preferences > Shape > Imagine & Shape > Display tab, Base Mesh, Line area.
