information how the model is built
B) An assembly document (.sldasm), which
contains the relative positions of components

Build a Sketch:-
1. Click “Sketch” Icon
2. Select a plane or a planar face
3. Draw a profile (with lines, curves and/or
centerlines)
4. Add geometrical constraints (relations)
5. Add dimensional constraints & modify the
values

Construction Geometry
Construction geometry is created within a
sketch to aid in profile creation. Only
standard geometry will be used for
creating solids or surfaces (Fig.1)
Construction geometry is shown in
dashed format. To convert an element
into a construction element, select it and
activate the option” for construction”.
You can also toggle any construction
elements from construction to standard
by deselecting the option.

Constraining the sketch
• Dimensional Constraints
(click the icon, then select the element(s))
• Length
• Distance
• Angle
• Radius/Diameter
Remark: To discontinue the command, click
the icon again.
• Geometrical Constraints
(multi-select the two elements by
pressing “CTRL” key and click the icon)
• Perpendicularity
• Horizontal/Vertical
• Concidence
• Tangency
• Symmetry (multi-select the elements on the
both side and then select the centerline)
You can also create constraints with other
sketches and 3D elements out of the sketch
To show or hide all geometrical constraints on the
screen, select “View / Sketch Relations”

2. Black: Fixed/Fully constrained
3. Red: Over-constrained
Only case 1 & 2 are allowable. For
case 3, you must fix the error
before quitting the sketch mode,
otherwise a warning message will
pop-out and you cannot continue
until the error is fixed.

View Orientation• By default, the screen is parallel to the
sketch support.
• To making constraints between the sketch
geometry and the 3D element, you may
need to rotate the model into a 3D view.
• To return the default orientation, press
“space” key on the keyboard to activate the
menu of orientation, and then select “Normal
to” (the viewpoint normal to the sketch plane)
We can create a distance
constraint between the circle
centre and the solid edge

Part /Assembly Drawings
We can create a 2D drawing from a part
or an assembly. They have the parent-
and-child relationship; 3D model is the
parent and the drawing is his child. If the
3D model is changed, the drawing will be
changed automatically.
The file extension of Solidworks drawings
is *.slddrw, no matter it is a part drawing
or an assembly drawing.
Same as the assembly file, the drawing
file cannot be opened properly if the
system cannot locate the part/assembly
file.
Wherever when we open the drawing file,
the system will try to locate the parent
part/assembly file to update all the views.
2D Drawing

change 2D, but not vice versa

Create Views
To create a 2D drawing:-
•Select “File/New…” on the menu
•Click “Drawing” and then OK
•Select a template, e.g. A-4 Landscape
•Click “Browse”, the select a part /assembly file
•Then Select “Single View” or “Multiple Views” (Single view – create
views one by one and we can see the preview; Multiple Views – create
many views at one time by highlighting the view icons below)
•If you want to scale down the view to fit it onto the paper, you can use
“Custom size”. But generally, we prefer using a bigger paper to making
the model views smaller.
To change the properties of the 2D drawing:-
•Right-click on the paper and then select “Properties”
•We can now change the paper size and also change the projection
method. (By default, First Angle projection is used. First Angle
projection is commonly used in China, but Third angle projection is
used in United states and Taiwan.)
•(Remark: After the projection method is changed, all existing views will
be updated correspondingly)

To add or remove curves on a view:
(For dependent curves, projected from 3D)
-We can only hide the curve that we don‟t want to see. We
cannot delete it.
-To hide the curve, right-click on the view and then select
“Hide edge” then select the curve

To Define an Equation to control parameter(s):-
(Use a simple box as an example)
• Height (30) = Length(80) - Width (50)
• Define “Length” and “Width” as the driving parameters,
“Height” as the driven parameter.
• Select “Tools /Equations” on the menu bar
• Click “Add..”
• Double-click the feature to show all related parameters
• Select the driven parameter
• Type „‟=“
• Select a driving parameter, then type “-”
• Select the other driving parameter, then click ok
• (The equation is added. Now the parameter “Height” is driven
by “Length” and “Width”
To Create a Design Table to control parameter(s):-
• Select “Insert/ Design Table” on the menu bar
• Select “Blank” as source; Select “Block model edits that would
update the design table”; Deselect the below three options
• Click ok to create
• Double-Click on the feature “Extrude1” to show all related
