Move a free point:
By default, free points are red. You click on  the point and  projections in planes xy, yz et xz are drawed. Left button pressed, you move one projection, point is moved and all the figure is rebuilded .

Create a new free point
This point, is by default (0,0,0). Projections in planes xy, yz et xz are showed and you can place the point where you wish.

Drawing a segment
Click on two points, free or not, and the segment is created.

Top

Drawing a line
Click on two points, free or not, and the line is created.

Drawing a parallel
Click on a point, free or not, and a line or a segment to give direction.
Select order has no importance.

Drawing a perpendicular

Click on a point, free or not, and a line or a segment to give direction.
Select order has no importance.

Top

Drawing intersections
You can choose two segments, one segment and one line, two lines, one segment and one plane, one line and one plane or two planes. Select order has no importance.

Drawing midpoint of two points or of a segment
Click on two points, free or not, or on one segment.

Top

Drawing a plane perpendicular to a line
Click on one point, free or not, and one line or one segment. The plane will be perpendicular and passed through the point. Select order has no importance.

Drawing a plane parallel to another plane
Click on one point, free or not, and one plane. The plane will be parallel and passed through the point.
Select order has no importance.

Drawing the mediator plane of two points or one segment
Click on two points, free or not, or on one segment. The plane will be perpendicular and passed through the midpoint of points.

Top

Drawing a plane through one line and one point
Click on one point, free or not, and one line or one segment. The plane will  passed through the point and the line or segment. Select order has no importance.

Drawing a plane through two lines 
Click on two lines. The plane will  passed through the lines if they are in a same plane or parallels.
You can also choose two segments or one segment and one line.

Drawing a plane through three points
Clich on three points, free or not, the plane will  passed through the three points if they are not on a same line. 
.

Top

Drawing a circle by three points
Clich on three points, free or not, the circle will  passed through the three points if they are not on a same line.

Drawing the centre of a circle
Select one circle, the point will be the center of the circle.

Dilating an object
You enter scale factor in dialog box. You select center of dilation, point free or not, and the object to be dilated, point, segment, line, plane or circle.

Top

Reflecting an object through a plane
You select one plane as mirror and the object to be reflected, point, segment, line, plane or circle.

Reflecting an object through a line
You select one line as mirror and the object to be reflected, point, segment, line, plane or circle.

Translating an object
You select two points, free or not,  as vector and the object to be translated, point, segment, line, plane or circle. Caution:  vector of translation begin with first selected point

Top

Put a point on an object
You click on a line or a circle, one point is created on this line or this circle.You can drag the constructed point, but it always stays on the object on which it was created.

Drawing the locus of a point or a line
Select a point on object and one constructed point or one line. If the locus object is a point, you will have a  continuous curve stitched together from sampled locations of the point as the driver point moves along its path. Otherwise the locus will be a set of lines.

Put a point by coordinates
This command allows you to type in the coordinates of points you wish to plot in the coordinate system.

Coordinates of a point
You select a point, free or not. The coordinates of the selected point will be displayed in html page. The coordinates will be actualised when you move the point.  

Distance between two points or length of a segment
This command displays the distance between two selected points or the length of a selected segment.

Know if two lines are coplanares
You select two lines. You will know if they are coplanares or not.

Change the perspective
You can change values of the two angles, horizontal angle and vertical angle.
Left button pressed, you move the red points on the circles and the figure is redrawed with new values.
