Maud ul: Information Technology. 5 3.

Entering objects in 3 D COMPASS



Purpose of the module: Mastering the input objects to the COMPAS panel Geometry 3 D.

1. Total light Denia on the geometric objects

The geometric objects in the system KOMPAS 3D include:

- Points

- Support direct

- Segments

- Circle

- Ellipses

- Arc

- Polygons



- Broken,

- Bezier curves,

- NURBS,

- Hatching and shading,

- Equidistant,

- Contours.

Teams create these objects are grouped in the Tools menu - Geometry, and buttons to invoke commands - Panel geometry.

2. Creating (building) geometric object s

Supporting direct

To construct a randomly located straight line, call the team a straight line .

Specify the first point, through which must pass straight - T1. If you know the position of the second point, belonging to the line (T2), ask her.

To construct a horizontal line, invoke the command horizontal line.

Ask a point through which must pass a straight line.

To construct a vertical line, call the team a vertical line.

Remnant ki

To construct a random interval, call the command segment .

Set the starting point of the segment T1. If you know the position of the endpoint of the segment T2, ask her. The length and angle of the segment will be determined automatically. If you know the length and angle of the segment, type them in the appropriate fields on the property bar.

To construct a segment parallel to a straight-line object, call the command parallel segment.

Specify the object, parallel to which is to be cut. Set the starting point of the segment T1.

To construct a segment perpendicular to the straight-line object, call the command perpendicular to the segment.

Specify the object, which is to be perpendicular to the segment. Set the starting point of the segment T1.

Circles and

To build an arbitrary circle, invoke the command Leg . Specify the center of the circle.

Specify the radius or the diameter of the circle.

By default, the circle built without axial lines. At the same time in the Axes group on the Properties pane is active switch without axes. To create a circle had the axial line, activate the switch with axes.

To construct a circle passing through three given points, call the command circle by three points.

Set the T1, T2 and T3, must pass through the circle. Center Coordinates of the circle and its radius will be determined automatically.

Doug and

To build an arbitrary arc, call the Arc command . Set the center point of the arc.

Set the starting point of the arc. Specify the endpoint of the arc. By default, when you enter the parameter of the circle system is waiting for input radius. Thus in a group setting is active switch radius. To enter the diameter, activate the switch diameter.

Rectangle and

To build an arbitrary rectangle, call the command Rectangle . Set the first vertex of the rectangle R1.

If the position of the second peak T2 is known, ask her.

To construct a rectangle with a given center, call the Rectangle command center and top.

Set the center of the rectangle.

If the position of one of the vertices of the rectangle m1 know, ask her.

Polygon and

To construct a regular polygon, invoke the command Polygon. By default, the polygon based on the inscribed circle. To enable the construction of the circumcircle, activate the switch by the circumscribed circle.

Enter the number of vertices of the polygon in the appropriate box on the Properties pane. Set the center point of the polygon.

If you know the position of the point t - One of the vertices (in the construction of the circumcircle) or the middle of one of the parties (in the construction of the inscribed circle) of a polygon, specify this point.

If you know the radius or diameter, and the angle of the polygon, enter them in the appropriate fields on the property bar.

Continuous input

To build on the sequence of segments and arcs, invoke the command continuous input objects .

When you enter the sequence of the endpoint object created automatically becomes the starting point of the next object.

Bezier curves

Thurs Oba construct a Bezier curve, Bezier curve command call . Ask a point, must pass through Bezier curve. Fix the Bezier curve created by clicking Create object.

Chamfer

To construct a segment connecting two intersecting curves, call the command Chamfer .

With the help of switch type on the Properties pane, specify the method for constructing facets: two lengths or the length and angle. Enter the first and second objects between which to build an edge.

To build a chamfer on the corners of the objects of the following types: contour, polygon or a polygon, invoke the command Chamfer the corners of the object.

By default facet is built only at a specified angle of the contour. At the same time in group mode on the properties panel active switch at a specified angle. To chamfer with given parameters simultaneously formed in all the corners of the selected contour, activate the switch on all the corners of the contour.

Curving

To build rounding circle arc between two intersecting objects, invoke the command rounding . Enter the radius of curvature of the corresponding field in the Properties pane. Specify the two objects, between which is necessary to build rounding.

To build a curving arcs of the circle at the corners of the objects of the following types: contour, polygon or a polygon, invoke the command rounding the corners of the object.

Enter the radius of curvature of the corresponding field in the Properties pane. Specify the angle of the contour, polygon or broken line on which you want to build a fillet.

Hatch and

To stroke one or more areas, call the command Hatch . Specify the border and shading options. When all the desired area will be shaded, click Create object.

Equidistant

To build equidistants any geometric object, call the Koman do equidistant curve . Specify the object equidistants which you want to build. You will see a phantom equidistant.

Configure equidistant. All the changes are displayed on the phantom. When you are ready, click Create object.

3. The principles of writing and editing drawing objects

Create object - hence determine all its parameters.

In designing fashion lei and drawings using 3D KOMPAS all options created objects are displayed on the properties.

Fig. 1. Properties panel segment

Parameters can be divided into numbers (coordinates, length, angle, number of vertices, etc.) and non-numerical (line style, the presence of symmetry axes, etc.). Next to the name of the majority of numerical parameters on the properties panel is a switch on that displays the icon corresponding to the state parameter:

o The reported

o Active

o Support

H echislovye parameters of the object can specify only one way - by selecting the desired option on the property bar. D To set the numerical parameters is available several ways.

1) an indication of the required points in the document window.

2) input parameters in the predetermined order

3) Setting parameters on the properties panel.

The value of each parameter is displayed in a separate box to the left of which is written a short name of the parameter. For segment T1 - the coordinates of the initial point, T2 - the coordinates of the endpoint, length - the length, angle - the angle of inclination of the axis X of the current system of coordinates.

To the left of the name parameter is a small button. If it displays a check mark This means that the system is currently waiting for input for this parameter.

Fig. 2. Properties panel segment

Once the value given, and the parameter is fixed, the button at a picture of cross . If the button is empty, then the parameter is a subsidiary (as the length and angle in the case of a segment), while it is available for input.

To obtain current information about the parameter field, place the cursor on it. After some time near the cursor will tab-tip with the name of the parameter

Input parameters

There are several ways to enter values into fields of object properties panel. We describe them as an example of constructing the segment.

1. If you move the cursor to the point, which will be the beginning of the segment, and commit it in the field of T1 will be automatically entered the coordinates of this point. In the button next to the crosshair will appear, indicating that the parameter is fixed.

2. In order to explicitly enter a value in the parameter field, click the left mouse button. The field will be available for editing, and you can dial the desired number.

After entering a value in the parameter field should switch to another field or press .

3. You can perform the input parameters, removing them from the existing volume projects. To do this, Compass provides a powerful apparatus of geometric calculator.

Memorizing Settings

Very often you want to draw a few objects that have the same number of parameters. A typical example is the construction of concentric circles, in which matching options would dot center.



Call the team constructing the circle, pressing the circle dashboard.

Fix the point of the circle, and then click Save state on a special control panel.

Now consistently indicate points lying on the circle. All of these circles will be built from a single center, and the system will not wait for guidance center for each new circle.

Automatic and manual creation of objects

After the call most commands input objects on a special control panel displays the two buttons. One of them, Automatic creation of object The default is pressed. If you keep this button pressed, then all objects will be created immediately after entering their parameters.

If you do not want the objects created automatically, press this button. Now, in order to confirm the creation of each of the next element, you will need to click Create object. .

Use for line-editing features

The processes of writing and editing tion of objects in COMPASS similar. In order to start editing an existing object, double-click the left mouse button on the site.

The line properties of the objects will contain the fields that characterize the parameters of the specified object. Change the settings and click .
