Shapes Construction

The shapes group is used to create and draw shapes,constructions such as axis, intersections, lines and so on.

There are six possible features, each with a guide will prompt on right hand of the screen. Points, lines and circles specified on the guides are both primitive or shapes already create on the 2DVisualizer.

• Rectangles:

Instruction step by step:

 1) Set one point set a second point confirm to construct a rectangle passing through them 2) Set one point set a second point set a third point confirm to construct a rectangle passing through them 3) Select a line set one point Select another point confirm to construct a rectangle with the first point as centre, the second point as vertex and one side parallel to the line
• Circles:

Instruction step by step:

 1) Set one point set a second point confirm to construct a circle with the first point as a centre and passing through them 2) Set one point set a second point confirm to construct a circle passing through them 3) Set one point set a second point set a third point confirm to construct a circle passing through them 4) Set one point set a second point set four or more points confirm to construct a circle passing through them

• Arcs:

Instruction step by step:

 1) Set one point set a second point set a third point confirm to construct an arc passing through them

 2) Set one point set a second point set a third point confirm to construct an arc with the first point as a centre and passing through the other two. The construction is done drawing the line clockwisely from the second point to the third.

• Lines:

Instruction step by step:

 1) Select one line Select another line Confirm to construct the bisector of the angle between them

 2) Select a circle Confirm to construct the two orthogonal diameters parallel to the axes

 3) Select an arc Confirm to construct the two orthogonal diameters parallel to the axes

 4) Select a point Select another point Confirm to construct a line connecting them

 5) Select a line Set one point Confirm to construct the parallel of the line passing through the point The parallel just built is not bounded to the point, the offset can be set manually from the property bar

 6) Select a line Set one point Confirm to construct the parallel of the line passing through the point, bounded to it

 7) Select a line Set one point Confirm to construct a line passing through the point, by default the angle is 0 The angle can be set manually from the property bar

 8) Select a line Set one point Confirm to construct the orthogonal of the line passing through the point

• New Ucs (User coordinate system) Reference:

Instruction step by step:

 1) Set a point Confirm to set a new Ucs centred in the point

 2) Select a line Confirm to set a new Ucs centred in the point, having as x axes the parallel of the line

• Points:

1)

Instruction step by step:

 2) set a point Confirm to make it as a part of the object
 3) set a point set another point Confirm to obtain the midpoint

 4) set a point set another point Confirm to obtain the vertex of the rectangle built taking the two points as opposite vertexes

 5) Select a line Select another line Confirm to obtain the intersection point (also in the extensions)

 6) Select a line Select a circle Confirm to obtain the intersection point(s)

 7) Select an arc Select a line confirm to obtain the intersection point(s) (also in the extensions)

 8) Select one circle Select another circle Confirm to obtain the intersection point(s)

 9) Select an arc Select another arc Confirm to obtain the intersection point(s) (also in the extensions)

 10) Select a circle Select an arc Confirm to obtain the intersection point(s) (also in the extensions)

When you select a shapes, a guide will prompt in order to suggest you what you can do.
