The following
explains the creation of connection points at miters.
In the
example, we have a profile with cross-section dimension 80 mm x 40
mm and a miter of 45°.
The connection points start_ab,
start and start_ba
should be positioned for all possible miter angles.
Connection point at miter
angle
Do the
following:
Create the
profiles normally.
In the
Variable Manager, insert the variables
SAX, SAY (start side) and EAX, EAY (end side) for the input of the miter angle; in addition SDX, SDY,
EDX, EDY with StatusAttribute algorithms as help variables to
calculate the Distance plane
(see figure below).
Variable Manager
In the
Variable Manager define the Attribute algorithms for the help variables
SDX, SDY, EDX, EDY.
SDX =
ABS(20*TAN(SAX))
SDY =
ABS(40*TAN(SAY))
EDX =
ABS(20*TAN(EAX))
EDY =
ABS(40*TAN(EAY))
With the help
of these variables the movement of the Distance plane is calculated (see figure
below).
Attribute algorithms dialog window
Create the absolute level with the
Base point in the midpoint of the section.
(Here in figure bottom "Fixed plane
1")
Fixed plane 1 - Base point
Fixed plane 1 - Settings
In the context menu, click on
Insert new plane....
In the Type list field, select the
point Plane with distance.
In thed Distance field, enter the
following:
IF SAY = 0 THEN SDX ELSE SDY
ENDIF
In the following example, the miter
angle is 45°.
The resulting Distance both are 40 mm.
Base miter start

Again click on the Insert new plane... context
menu.
In
the Type
list field, select the point Plane with rotation.
In
the Angle
field, enter "SAY".
In
the Turn around list field, select point X axis.
In
our example, "SAY" has 45°.
=> The plane is moved 45° around
the X-axis.
Rotation miter start Y
Rotation miter start Y
Create a Plane with rotation
again.
Under Angle enter the
following:
IF
SAY = 0 THEN SAX ELSE 0 ENDIF
(Only SAY or SAX are recognized)
In
the list field Turn around, select point Y axis.
In
our example, the rotation occurs around the Y-axis
0°.
Rotation miter start X
Create a sketch for the Extrusion solid and enter the
following:
Length:
IF
SDY = 0 THEN SDX*2 ELSE SDY*2 ENDIF
Set a checkmark at Only create, if.
The Cut extrusion should only be
created if SAY or SAX are unequal to '0'.
Cut extrude 1
Extrusion solid
Then create the sketch with the
connection points.
Sketch with connection
points
The creation of
the "End" connection point occurs in the same way as described above.
