Multi-Grips Edit Mode

May 20, 2011

       It's also enabled to manipulate grip edit mode using multiple grips. You can press SHIFT to select multiple grips. Once you have selected multiple entities (called hot multi-grip selection), the part of entities among grips will not change.


Using Multi-Grips edit mode is sorted into the following two cases:

  •      To move, rotate, scale or mirror entities, using multiple grips on them equals to use the last selected grip as base point (base grip or new selected base point).

  •      To stretch entities, multi-grips are selected depend on the type of entities, when you selected single text point, insertion point of block reference, midpoint of line, center of circle and grips on point object as hot grips, the entities will be moved rather than stretched.


Multi-Grips Stretch Mode

Select multiple grips of different entities to stretch separately depend on the entity types.

Stretch Lines, Polylines and Dimensions Using Multiple Grips

  1. Select line, polyline and dimension entities to stretch.

  2. Press SHIFT while selecting grips on entities, the selected grips will be highlighted.

  3. Release SHIFT and click on one of the selected grips to use it as base grip and activate the default grip mode as Stretch. Dynamic input box displayed on screen showing the following manipulations:

  • Specify "B(Base point)" option to locate the grip for stretching.

  • Specify "C(Copy)" option to create a copy of the entity being stretched.

  • Specify "U(Undo)" option to abort last stretch.

  • Specify "X(eXit)" option to exit stretch manipulation.

  • Specify target location for stretching directly.

  1. Move the pointing device to specify target grips, the selected grips on entities will be stretched or moved towards the direction pointing from the base grip to the target location (single text point, insertion point of block reference, midpoint of line, center of circle and grips on point object).


Multi-Grips Move Mode

Move entities with multiple grips mode, use the last grip ( base grip or reselected base point) as base point.


Move Lines, Polylines and Dimensions Using Multiple Grips

  1. Select line, polyline and dimension entities to move.

  2. Press SHIFT while selecting grips on entities, the selected grips will be highlighted.

  3. Release SHIFT and click on one of the selected grips to use it as base grip.

  4. Press ENTER to activate the default grip mode as Stretch. Iterate grip mode until Move appears in command line. Dynamic input box displayed on screen showing the following manipulations:

  • Specify "B(Base point)" option to locate the base point for moving.

  • Specify "C(Copy)" option to create a copy of the entity being moved.

  • Specify "U(Undo)" option to abort last moving.

  • Specify "X(eXit)" option to exit move manipulation.

  • Specify target location for moving directly.

  1. Move the pointing device to specify target location, the selected grips on entities will be moved at a specified displacement towards the direction pointing from the base grip to the target location.


Multi-Grips Rotate Mode

Rotate entities with multiple grips mode, use the last grip ( base grip or reselected base point) as base point.


Rotate Lines, Polylines and Dimensions Using Multiple Grips

  1. Select line, polyline and dimension entities to rotate.

  2. Press SHIFT while selecting grips on entities, the selected grips will be highlighted.

  3. Release SHIFT and click on one of the selected grips to use it as base grip.

  4. Press ENTER to activate the default grip mode as Stretch. Iterate grip mode until Rotate appears in command line. Dynamic input box displayed on screen showing the following manipulations:

  • Specify "B(Base point)" option to locate the grip for rotating.

  • Specify "C(Copy)" option to create a copy of the entity being rotated.

  • Specify "U(Undo)" option to abort last rotation.

  • Specify "X(eXit)" option to exit rotate manipulation.

  • Specify "R(Reference)" option to assign reference angle for rotation. (Final rotation angle=reference angle subtract from input angle. For example: reference angle = 20, input angle= 80, final rotation angle = 80 - 20 = 60).

  • Specify rotation angle for grips directly.

  1. Move the pointing device to specify rotation angle, the entities will be rotated based on the selected grip (or create a copy of the entity after rotation).


Multi-Grips Scale Mode

Scale entities with multiple grips mode, use the last grip ( base grip or reselected base point) as base point.


Scale Lines, Polylines and Dimensions Using Multiple Grips

  1. Select line, polyline and dimension entities to scale.

  2. Press SHIFT while selecting grips on entities, the selected grips will be highlighted.

  3. Release SHIFT and click on one of the selected grips to use it as base grip.

  4. Press ENTER to activate the default grip mode as Stretch. Iterate grip mode until Scale appears in command line. Dynamic input box displayed on screen showing the following manipulations:

  • Specify "B(Base point)" option to locate the grip for scaling.

  • Specify "C(Copy)" option to create a copy of the entity being scaled.

  • Specify "U(Undo)" option to abort last scaling.

  • Specify "X(eXit)" option to exit scale manipulation.

  • Specify "R(Reference)"option to assign reference scale factor. (For example: input scale factor as 5, to scale the entity to 5 times of its original size).Then dynamic input box displays on the screen, in which you are prompt to enter new length ( if input 3, the entity will be scaled with the factor 3/5).

  • Specify scale factor for grips directly.

  1. Move the pointing device to specify target grips, the entity will be scaled based on the selected grips with the factor you specified ( or create a copy of the entity after scaling).


Multi-Grips Mirror Mode

Mirror entities and create their copies with multiple grips mode, use the last grip ( base grip or reselected base point) as base point.


Mirror Lines, Polylines and Dimensions Using Multiple Grips

  1. Select line, polyline and dimension entities to mirror.

  2. Press SHIFT while selecting grips on entities, the selected grips will be highlighted.

  3. Release SHIFT and click on one of the selected grips to use it as base grip.

  4. Press ENTER to activate the default grip mode as Stretch. Iterate grip mode until Mirror appears in command line. Dynamic input box displayed on screen showing the following manipulations:

  • Specify "B(Base point)" option to relocate the base grip.

  • Specify "C(Copy)" option to create a copy of the entity being mirrored.

  • Specify "U(Undo)" option to abort last mirroring.

  • Specify "X(eXit)" option to exit mirror manipulation.

  1. Move the pointing device to specify second mirror point, the entity will be mirrored along the line connecting the selected grip on objects and the second mirror point ( or create a copy of the entity after mirroring).
