Insert

 

Commands for inserting new entities.

 

Line 2 points

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 doesn’t 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 command Detach.

 

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 their ISO 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 command Modify text for dimensions).
