1) Creating Corners
This task shows how to create a rounded corner (arc tangent to two curves) between two lines using trimming operation. You can create rounded corners between curves. Click the Corner icon
from the Operations toolbar. The possible corner options are displayed in the Sketch tools
toolbar: the Trim All Elements option command
is
activated by default. Select the two lines. The second line is also
highlighted, and the two lines are joined by the rounded corner which
moves as you move the cursor. This lets you vary the dimensions of the
corner. Enter the corner radius value in the Sketch tools toolbar. You
can also click when you are satisfied with the corner dimensions.
2) Creating Chamfers
This task shows how to create a chamfer between two lines trimming either all, the first or none of the elements, and more precisely using one of the following chamfer definitions:
Angle/Hypotenuse, Length1/Length2, Length1/Angle. Click the Chamfer icon
from
the Operation toolbar. The possible chamfer options are displayed in
the Sketch tools toolbar. Trim All / First / No element. Select the two
lines. Click when you are satisfied with the dimensions of the chamfer.
3) Trimming Elements
Trimming two elements: This task shows how to trim two lines (either one element or all the
elements). Create two intersecting lines. Click the Trim icon
from
the Operations toolbar. The Trim toolbar options display in the Sketch
tools. The Trim All option is the command activated by default. Select
the first line. Position the cursor on the element to be trimmed. The
location of the relimitation depends on the location of the cursor.
Trimming one element: This task shows how to trim just one element. Click the Trim icon
from the Operations toolbar. Click the Trim One Element option
. Select the two curves. First curve will only be trimmed by second curve.
4) Breaking and Trimming
This task shows how to quickly delete elements intersected by other Sketcher elements using
breaking and trimming operations. Click the Quick Trim icon
from
the Operation toolbar (Relimitations subtoolbar). The possible trim
option commands are displayed in the Sketch tools toolbar. These
options are Rubber In, Rubber out, and Break.
5) Closing Elements
This task shows how to close circles, ellipses or splines using relimiting operation. Click the Close
icon
from
the Operation toolbar (Relimitations subtoolbar). Select one or more
elements to be relimited. For example, a three point arc. The arc will
now be closed.
6) Complement an Arc (Circle or Ellipse)
This task shows how to complement an arc (circle or an ellipse). Create a three points arc. Click on
the arc to be complemented to select it. Click the Complement icon
from the Operation toolbar (Relimitations subtoolbar). The complementary arc appears for selected arc.
7) Breaking Elements
The Break command lets you break any types of curves. The elements used for breaking curves
can be any Sketcher element. Click the Break icon
from
the Operations toolbar. Select the line to be broken. Select the
breaking element The selected element is broken at the selection. The
line is now composed of two movable segments.
8) Creating Symmetrical Elements
This task shows you how to repeat existing Sketcher elements using a line, a construction line or
an axis. Select the profile to be duplicated by symmetry. Click the Symmetry icon
from the Operations toolbar. The selected profile is duplicated and a symmetry constraint is created on the
condition you previously activated the Dimensional Constraint option
from the Sketch tools toolbar.
9) Translating Elements
This task will show you how to perform a translation on 2D elements by defining the duplicate mode and then selecting the element to be duplicated. Multi-selection is not available. Click the
Translation icon
from the Operation toolbar (Transformation subtoolbar). The Translation
Definition dialog box displays and will remain displayed all along your
translation creation. Enter the number of copies you need. The
duplicate mode is activated by default. Select the element(s) to be
translated. Click the translation vector start point or select an
existing one. In the Translation Definition dialog box, enter a precise
value for the translation length. Click OK in the Translation
Definition dialog box to end the translation.
10) Rotating Elements
This task will show you how to rotate elements by defining the duplicate mode and then selecting
the element to be duplicated. Click the Rotation icon
from
the Operations toolbar (Transformation subtoolbar). The Rotation
Definition dialog box appears and will remain displayed all along the
rotation. De-activate the Duplicate mode, if needed. Select the
geometry to be rotated. Here, multi-select the entire profile. Select
or click the rotation center point. Select or click a point to define
the reference line that will be used for computing the angle. Select or
click a point to define an angle. Click OK in the Rotation Definition
dialog box to end the rotation.
11) Scaling Elements
This task will show you how to scale an entire profile. In other words, you are going to resize a
profile to the dimension you specify. Click the Scale icon
from
the Operation toolbar (Transformation subtoolbar). The Scale Definition
dialog box appears. Select the element(s) to be scaled. Enter the
center point value in the Sketch tools toolbar or click the center
point on the geometry. Enter Scale Value in the displayed Scale
Definition dialog box. Selected elements will be scaled according to
scale factor.
12) Offsetting Elements
This task shows how to duplicate an element of the following type: line, arc or circle. Click the
Offset icon
from
the Operations toolbar (Transformation subtoolbar). There are two
possibilities, depending on whether the line you want to duplicate by
offset is already selected or not: If the line is already selected, the
line to be created appears immediately. If the line is not already
selected, select it. The line to be created appears. Select a point or
click where you want the new element to be located. The selected line
is duplicated. Both lines are parallel.
You can also apply one or more offset instances to profiles made of several elements. You can offset elements by using tangency propagation or point propagation, by creating an offset element that is tangent to the first one, by creating several offset instances.
13) Projecting 3D Elements onto the Sketch Plane
This task shows how to project edges (elements you select in the Part Design workbench) onto the
sketch plane. Click the Project 3D Elements icon
from
the Operations toolbar (3D Geometry subtoolbar). Multi-select the edges
you wish to project onto the sketch plane. The edges are projected onto
the sketch plane. These projections are yellow.
14) Intersecting 3D Elements with the Sketch Plane
This task shows how to intersect a face and the sketch plane. Select the face of interest. Click the
Intersect 3D Elements icon
from
the Operations toolbar (3D Geometry subtoolbar). The software computes
and displays the intersection between the face and the sketch plane.
The intersection is yellow.
15) Creating Silhouette Edges
This task shows how to create silhouette edges to be used in sketches as geometry or reference
elements. Click the 3D Silhouette Edges icon
from
the Operation toolbar (3D Geometry subtoolbar). Select the surface. The
silhouette edges are created onto the sketch plane. These silhouette
edges are yellow if they are associative with the 3D. You cannot move
or modify them but you can delete one of them which means deleting one
trace independently from the other.
Cutting the Part by the Sketch Plane
This task shows how to make some edges visible. In other words, you are going to simplify the sketch plane view by hiding the portion of material you do not need for sketching. Select the plane on which you need to sketch a new profile and enter the Sketcher workbench. Click the Cut Part by
Sketch Plane icon
on
the Tools toolbar to hide the portion of part you do not want to see in
the Sketcher. You can now sketch the required profile.
Customizing for Sketcher
Select the Tools -> Options command to display the Options dialog box. The Options dialog box appears. Expand the Mechanical Design option, and then click Sketcher. The Sketcher tab appears, containing the following sets of options: Grid: options available Display, Primary spacing, Graduations, Snap to point and Allow Distortions Sketch Plane: options available Shade sketch plane, Position sketch plane parallel to screen. Geometry: options available Create circle and ellipse centers. Constraints: options available Create detected constraints Colors: options available Visualization of diagnostic.
