Selecting 2D Objects

While working with 2D objects, you almost always need to select other objects. In a typical function, you must select one or multiple objects, finish the selection, and then the function processes the selected set. For example, selection is used when deleting objects, translating objects, changing object color, etc. Temporary toolbars provide selection options.


Methods of Selecting

The most direct way to include objects in the selection set is to left-click on them. Objects are selected if they are within the cursor aperture, and selected objects are highlighted in a different color.


A temporary toolbar appears during object selection, which provides additional selection options. All options are also available on the Select menu. You can select single objects, or groups of objects that share attributes such as a particular color. You can select groups of objects from the entire drawing, or you can use selection windows. You can also access selection options by entering the relevant command keys (which are not case-sensitive). When using commands, the desired object must already lie within the cursor aperture.

Selecting Types of Objects

These options enable you to select single objects of a certain type that are found within the cursor aperture. When using these selection options, automatic detection is irrelevant.


IconKeyUse
LSelects a line
QSelects a spline
ASelects an arc or circle
PSelects a point
SSelects a symbol
Shift + 6 (^)Selects an arrow
CSelects a hatch
NSelects a text
DSelects a dimension

Selecting Groups of Objects

IconKeyUse
N/ASelects all objects
RSelects objects completely inside the selection window
ISelects objects completely or partially inside the selection window
USelects objects completely or partially outside the selection window
OSelects objects completely outside the selection window
VSelects objects on a specified layer
BSelects objects of a specified color
YSelects objects of a specified line type
TSelects a group of objects of a specified type
1…8Selects objects from work set 1 - 8

Using Selection Windows (Marquees)

Run command CFG, section 2D and sub-section “2D Object Selection Settings”. Here you can determine when and how selection windows will be used. If, during a selection, you click in the drawing and nothing is selected, you can set the system behavior to do one of the following:


Selecting Objects Related to 3D Solids

IconKeyUse
ESelects a profile to be used to create a solid. The profile is selected segment by segment.
FSelects a profile to be used to create a solid. The profile is identified automatically.
MSelects all objects linked to a single 3D solid. These objects are created by exporting a 3D view.
GSelects all objects belonging to a 3D view export.

Limited 2D Selections

Some functions, such as Fillet and Chamfer, require you to select a limited number of objects. In this case, there is no need to finish the selection group. If you need to select two segments that share a corner, you can select the segments individually or select the corner itself. To select by using the corner, click when the V symbol appears on the corner. See also Creating Corners, Chamfers and Fillets.


Deselecting Objects

To delete objects from a selection set, click Select/Deselect icon and use the normal methods to select objects - each selected object will return to its unselected state. Pressing X while selecting will also deselect objects.

Finishing the Selection

Press Enter or right-click to complete the selection set, or click the corresponding icon in a toolbar.


Selecting 2D Locations

Most 2D objects require geometric input in the form of X, Y coordinates. VariCAD makes it easy to select certain significant locations relative to existing objects. To select a point on an object, move the cursor over the object so that it is highlighted. Clicking on the object will select the point closest to the cursor. If cursor approaches a snap point, such as an endpoint or midpoint, a symbol appears next to the cursor. Clicking when you see this symbol selects the point. The following letters indicate snap points:

LetterSnap Point
EEndpoint
MMidpoint
5Center of circle or arc
XIntersection
SConnection point of a symbol or block
10-deg point of a circle or arc
290-deg point of a circle or arc
3180-deg point of a circle or arc
4270-deg point of a circle or arc

You can also use icons, keys, and Snap menu items to specify snap points or other geometric locations. If you use the keyboard, the desired point must already be within the cursor aperture. The Snap menu also enables you to permanently use certain snaps.

MMidpoint
5Center of an arc or circle
ONearest point on an arc or line

FIntersection of two segments (select both segments, can also find intersection of segment extensions)
SpacebarNearest grid point
CIntersection of nearest construction lines

Combination of Location Points

IconKeyLocation
GDefined distance from the nearest line endpoint
AIntersection of a selected object and a line created from the last point at a specified angle
6Intersection of a selected object and a line created from the last point, perpendicular to this object
TTangent point on a selected object, directed from the last point
BHalfway between two defined points

Points Defined by Keyboard Input

IconKeyLocation
KEnter X, Y coordinates
DEnter DX and DY from the last point
REnter the distance and angle from the last point

Other Points and Functions

IconKeyFunction
WRedefine the user origin
IExact current cursor location
TABFixed length, angle or coordinate

Fixed Length, Angle or Coordinate

This method of 2D input allows you to use many convenient combinations. It is always available by pressing TAB. Then, a dialogue panel is open. If you continue pressing TAB, you change focus of input of X, Y, radius or angle value.

If you enter only one value, for instance X coordinate, next 2D input has fixed X coordinate. Or, if you enter only radius (length), next 2D input is always rounded to fixed distance from previous point. During drawing of line, you can create a fixed length segment.

If you enter two values, input is exactly defined. This allows you a combination of input of fixed coordinates, input of location in distance and under an angle etc…



Keyboard coordinates input


Defining Angles and Directions

Some functions, such as symbol insertion or mechanical part insertion, allow you to determine the rotation angle of inserted objects relative to line segments. Angles are measured counterclockwise from the +X direction (to the right of the origin).

To define an angle according a line direction, click a line. Then, four arrow icons appear – two along line, opposite each other. Next two arrow icons are perpendicular to line, opposite each other. Move cursor around the center of icons. Arrow in direction close to cursor is highlighted. Left-click a desired location, the current direction of angle is used.
