Creates a line that passes through two given points.
Broken
line
Creates a broken line (sequence of consecutive lines). The broken
line itself is not a single entity, the lines it is formed by are
single entities; as such they can be used and modified.
Parallel
through a point
Creates a parallel line to a selected existing line that passes
through the given point.
Sloped
Creates a new line that is inclined to the selected (existing) line
by an angle and that starts from the entered point (its first vertex).
The pick point determines direction and orientation of the new line:
it will be created rotated for the given angle towards the side of
the pick point with respect to the selected line. The angle is
measured from the line itself towards the vertex that is closest to
the pick point. If the line is visible only partly the visible part
is considered only. The length of the new line equals the length of
the selected line in case the entered is a point on the line,
otherwise the line passes from the entered point to the selected line.
Arc
Creates an arc that passes through three points.
The first and last point input define the initial and the final
vertex of the arc; the second point input determines the arc defining
a common point on the arc.
The three points cannot be aligned.
Circle center point
Creates a circle with center at the first point and passing through
the second.
Circle
3 points
Creates a circle that passes through 3 given points.
The three points cannot be aligned.
Text
Opens a window in which it is possible to enter a text without
limitations in size, and which can be disposed on one or more lines.
Then asks you to select the point where to insert the text.
Point
Creates an entity of the point type.
Rectangle
Creates a rectangle whose diagonal has the two selected point as
vertices. A rectangle is formed by a single polyline which consists
of several lines.
Polyline
Generates a polyline composed of linear stretches that connect the
input points. The End Selection
command, available from the context menu, finishes the insertion of
the points forming the entity.
Spline
Creates a spline as interpolation of the inserted points. The End
Selection command, available from the context menu, finishes
the insertion of the points forming the entity. The maximum of points
for the construction of a spline is 100.
Hatching
Lets you execute the hatching of a closed perimeter requiring the
input of only one side of the perimeter.
Selectable entities are lines, circles, arcs and ellipses.
The command doesnt consider eventual perimeters inside the
selected perimeter. The perimeter can be formed by a maximum of 5000 entities.
If the selected entity belongs to only one closed perimeter is
uninfluential the position of the center of the trap selection.
If the selected on primitive belongs to more of a closed perimeter
the position of the center of the trap selection becomes important,
as the search for the closed perimeter is "resting the right
hand" on primitive selected on the side of the center of the
trap selection and advancing until to return to the starting point.
In practice, you search the drawing area in which is the selection point.
If the center of the trap selection is within a closed perimeter
internal to others, this will be identified, if it is outside the
perimeter closed outermost of all, the latter will be identified.
Hatching
with Lakes
Creates a hatching of a closed perimeter by the selection of one
entity that belongs to it excluding the lakes, i.e. the
closed perimeters inside the perimeter.
Selectable entities are lines, circles, arcs and conics.
The entity has to be selected holding the selection cursor towards
the inside of the perimeter you want to hatch.
2
points dimension
Creates a dimension that measures the distance between the two points
positioning it in the third point inserted.
Angle
dimension
Creates a dimension that measures the angle formed by two lines
positioning it in the third point inserted.
Two intersecting each other lines form four angles. Which of these
angles will be dimensioned depends on the pick points of the
selection. In the first selection the exact position of the pick
point defines in which of the two half planes of the first line the
angle shall be; in the second selection the exact position of the
pick point defines in which of the two half planes of the second line
the angle shall be, this way you unequivocally determine the angle.
Diameter
dimension
Creates a dimension that measures the diameter of the circle (or of
arc) is selected positioning it in the point inserted.
If inserted point is inside the circle the dimension line will be the
diameter that passes through the point, if it is outside the
dimension line will be horizontal or vertical according to the
position of point.
Radius
dimension
Creates a dimension that measures the radius of the circle (or of
arc) is selected positioning it in the point inserted.
The dimension line is on the the line passing through the center of
the circle (or of arc) and passing through the point inserted.
More about dimensions
The position of the dimension text depends on the Optimum
dimensioning setting: if active the dimension is
automatically centered, otherwise it is positioned at the inserted
point. The Optimum dimensioning
can be set in the General page
of the CAD Options window.
The dimensions are associative, that is memorize which are the
entities that measure. This associativeness enables the dimension to
immediately adapt itself to a new geometric situation that may be
caused by the transformation or the modification of an entity.
You can delete this associativity with context
commandDetach.
Dimensions except for angle dimensions can be supplemented by tolerances.
Tolerances indicate the
maximum margin that the measured dimension is allowed to have with
regard to the nominal dimension. Tolerances can be set in
Dimensions
page of Attributes
window.
You can set tolerances as well by inserting theirISO
code. In this case the values of the upper and lower
tolerances are calculated automatically by the program that bases its
calculation on the ISO code and the size of the dimension.
The following schema illustrates a typical dimension:
abbr. description:
fq arrow
lq dimension line
lr reference line
pe extension point
pp projection point
pr reference point
t+ upper tolerance
t- lower tolerance
td text on the right
tq dimension text
ts text on the left
The texts on the right and on the left can be inserted during the
modifying of the dimension (see context commandModify
text for dimensions).
