Use the Drag panel to create a surface and/or mesh by dragging a series of nodes or lines, or to create elements by dragging selected elements. The function drags the selected entities along the specified vector creating a mesh, surface, or elements along that vector.

 

Examples

HM_Panels_bmp00089

Nodes are selected

HM_Panels_bmp00090

Nodes are dragged

HM_Panels_bmp00093

Elements are selected

HM_Panels_bmp00094

Elements are dragged

drag8

The elements in this illustration were created by using drag + with a positive bias intensity value.

drag9

The elements in this illustration were created without element biasing.

 

Subpanels and Inputs

The Drag panel contains the following subpanels and command buttons:

hmtoggle_arrow1Drag Geoms

A line segment can be used if desired.

The order in which the nodes are selected determines the connectivity of the mesh generated.

 

Panel Inputs

Input

Action

entity selector

Use this button to select whether to drag nodes or lines.

vector selector

Specify the direction along which to drag the nodes/line.

distance = / distance = N2- N1

Select which method to use for the distance to drag. If you select distance = , enter a value in the field.

mesh, keep surf

mesh, keep surf: creates a surface from the selected entities and then generates a mesh on the created surface.  The created surface is retained along with the mesh.

mesh, dele surf: creates a surface from the selected entities and then generates a mesh on the created surface.  The created surface is then deleted and only the corresponding mesh is retained.

mesh w/o surf: This option creates a mesh between the selected entities using linear interpolation without creating a surface.

surface only: creates a surface from selected entities, but does not create a mesh.  You can use the resulting surface to perform any desired geometry cleanup functions or automeshing.

 
hmtoggle_arrow1Drag Elems

When one-dimensional elements are dragged, two-dimensional elements are generated. When two-dimensional elements are dragged, three-dimensional elements are generated. Three-dimensional elements are ignored by the drag operator.

 

Panel Inputs

Input

Action

entity selector

Use this button to select the elements to drag.

vector selector

Specify the direction along which to drag the elements

distance = / distance = N2- N1

Select which method to use for the distance to drag. If you select distance = , enter a value in the field.

on drag =

Number of elements which should be generated along the drag

bias style

Select linear, exponential or bellcurve.

bias intensity

This affects how strong the biasing effect is.  Larger numbers create stronger bias.

 
expand-green-10Command Buttons

The following action buttons appear throughout the subpanels:

Input

Action

drag +

Drag the selection in a positive direction.

drag -

Drag the selection in a negative direction.

reject

Click reject immediately after the surface, mesh, or elements have been created.  To re-create the surface, mesh, or elements, click drag+ or drag- a second time without changing any of the input data.  The input entities used to create the surface, mesh, or elements are restored provided that no data have been selected since they were created.

return

Exits the panel.
