Contour
Menu access: Curve | Contour
Description:
Creates a contour passing on existing entities (points, lines, circles, and any wire frame entities...) or on new points.
General philosophy:
Select the starting sketch entity (can be a point or an edge)
Select the next sketch entities
Select on STOP, or select on the contour start to finish it
Available Option(s) :
The RECTANGULAR
button allows you to directly create a rectangular contour by two diagonal
points.
The button TURNING
allows
you to create a contour for turned shape through specific features.
You can swap at any time between
two pass mode:
Pass mode= PASS ON SEGMENT: default mode. You have to select each segment you want to use as sketch. Even for a composite curve (curve made of several lines, arcs or splines), you must select all the intermediate sections.
Pass mode= PASS ON COMPOSITE: in this mode, when you select a composite curve, the selected section is used as starting segment on this composite curve and a ending segment is asked. Then you can carry on the contour drawing by using new sketch entities or points.
This list 
allows you
to modify the link type between two consecutive elements.
This list 
allows you
to modify the join type between two elements by modifying the join option.
The >>
button
allows you to access to the following advanced options:
You
can use incremental angle for the construction of each part of the contour
by using this drop-down list : 
.
The option Make sketch invisible= YES or NO allows you to set the visibility of the next sketches elements.
You can automatically create a contour
passing on successive entities with common end points by using the AUTO LINK button.
When you finish your contour using
the STOP button, and the last selected element
is the same as the first one, you can choose, in certain cases, to create
an open contour using the OPEN STOP button.
Once you selected the STOP button, you can also set the sketches invisibles using the option Make sketches invisible= YES or NO
You can automatically dimension the
contour using the AUTO DIMENSION button.
Once the automatic dimensions created, you can add symmetry constraints to these dimension by using the SYMMETRY CONSTRAINTS button.
Example(s):
|
|
1. Point created on grid 2. Line selection, 3. Point created on grid, 4. Arc of circle selection, 5. New selection further on the same arc of circle (in order to avoid a tangent start), 6. Point created on grid. |
Specific point(s):
When creating the contour, the mouse
cursor change its appearance according to the constraint that will be
applied.
If the option auto
constraint is activated in the tools
menu, a parallelism constraint is automatically apply to the parts
that are parallel to the X or Y axis of the current coordinate system.
If you do not need them, you can:
Disable this option in the tool menu.
Delete afterwards the constraints you do not want.
When you select an arc, depending
on the selected point, you will arrive either tangent or orthogonal on
the element.
You can use the "rotative picking"
(holding left button down and click on the right button) to on a circle
or an arc to hook the contour on its center instead or the circle itself.
When you create a contour passing
on simple sketch elements (line, arc, polygon...) the created contour
is called re-passing
contour.
When you create a contour
on points type elements, the created contour is called contour
by point.
You cannot create a
re-passing contour over a 3D contour (Curve | Other curves | Contour 3D)
