Building planes |
Scroll |
In KOMPAS-3D you can construct:
•plane at an angle to another plane,
•plane through edge and point,
•plane though point parallel to another plane,
•plane through point perpendicular to edge,
•plane tangent to face at point,
•plane through edge parallel/perpendicular to another edge,
•plane through edge parallel/perpendicular to face,
|
Plane creation commands are grouped together. While executing a group command, you can switch to execution of another one using buttons of the Parameter Toolbar header. If an object to be built is already selected in the current command, it remains selected when you switch to another command (if an object of the same type is required for building). |
An auxiliary plane located at a specified distance from the specified flat object is built using the Offset Plane 
command. This command also enables building multiple offset planes in a single run.
Step-by-step instructions
1.Specify a flat object, relative to which the offset of the new plane is specified. The name of the selected object is displayed in the Base Plane field on the Parameters toolbar.
The phantom of the plane being created will appear in the graphics area.
2.In Distance field enter the distance from the flat object to the plane to be created.
3.Set the direction of the shift using the Change direction 
button to the right of the Distance field. After pressing the button, the arrow on the icon will change to the opposite.
4.If required, you can simultaneously build several planes which will be offset relative to each other at the specified distance. To do this, enter the number of planes in the Number. Phantoms of planes will appear in the graphic area.
|
Note that if multiple offset planes are created simultaneously, each of them will be displayed in the Model Tree as a separate object. You can edit each plane separately, independently from the others. |
5.To complete the build, click Create object 
.
6.To complete operation of the command, click the Finish 
button.

A bisector plane of a dihedral angle is built using the Median Plane 
command.
Dihedral angle – part of the space bounded by two half-planes, the boundary of each of which is their common straight line. These half-planes are called faces of the dihedral angle, and the straight line – edge of the dihedral angle. The angle between the lines of suppression of the faces of a dihedral angle with a plane perpendicular to the edge of the dihedral angle is called linear angle of the dihedral angle.
Bisecting plane of the dihedral angle is the plane passing through the bisector of the linear angle and the edge of this dihedral angle.
The dihedral angle for constructing the middle plane can be specified:
•faces – for this you need to specify two flat objects,
•linear angle – for this you need to specify two straight line objects,
•the face and side of the linear angle – for this you need to specify flat and rectilinear objects.
|
Dihedral angle and its bisector plane
Step-by-step instructions
Specify the sides of the dihedral angle to build a mid-plane.
A middle plane will automatically be created, the position of which relative to the specified objects depends on the position of the Position toggle switch.
•Position 1 — a bisector plane is constructed
•Position 2 — the plane is constructed perpendicular to the bisector plane and passing through the edge of the dihedral angle.
|
The position of the bisector plane must be specified before specifying the second side of the dihedral angle. |
In the particular case, if the specified objects are parallel, the constructive is performed as follows (regardless of the position of the toggle switch).
•If the objects are straight, then the middle plane is built perpendicular to the plane passing through them at an equal distance from them.
•If objects are planar, and also, if one is planar and the second is straight-line, then the median plane is built parallel to them at an equal distance from them.
To complete operation of the command, click the Complete button.
Additional features when building...
•The distance and angle values can be changed in the graphical area of the model – using defining points.
•You can set linear and angular parameters using the geometrical calculator.
•You may assign tolerances, specified in linear or angular units, to operation parameter values. To do this, you should call the Tolerance command located in the menu of the required parameter, or click the 
icon displayed in the parameter field (the icon is displayed if a tolerance is assigned to the parameter value). More details on assigning tolerance...
