This KEYCREATOR BASIC tutorial was design to help you become familiar with
the basic view manipulation, modeling functions, and file structure found in
KEYCREATOR. In this tutorial you will be modeling some of the components of
the toggle clamp shown above. Once you have completed the modeling
exercises you will assemble the various components of the clamp. When the
assembly is complete you will generate an associative detail drawing of the
model. You’ll make modifications to the model and view the updated detail
drawing. This tutorial was designed with the assumption that the user has had
general CAD software experience. For additional information on any of the
commands used in this tutorial, please refer to the reference manual shipped
with the product.

STEP 1 Familiarize yourself with the interface
There are several components in the KEYCREATOR interface. The figure above shows the
tree window. Don’t be alarmed if your interface does not show this window. The tree window
will be displayed later in the tutorial. The conversation bar is also an extremely important part of
the interface. As you progress through the tutorial, KEYCREATOR prompts will be displayed on
the conversation bar. The prompts will indicate the specific information that you’ll need to input
for the current modeling step. Watch the conversation bar for prompts throughout this tutorial.

You’ll use several methods to access commands during the tutorial. The windows pull-down
menus are an all-inclusive source for various modeling and system commands. Customizable
hot-keys and icons are alternate sources for accessing commands. You’ll use each of these
methods during the tutorial.
STEP 2 Open a Design file
The native file format for KEYCREATOR is the CKD file. Each CKD file can contain several
separate parts. Load the
KEYCREATOR_tutorial_mm.CKD
file. To do that choose FILE>OPEN
from the pull down menus. In the dialog box, select the file, and then click OPEN. This CKD file
contained three parts. Select “linkage bracket” in the dialog box then click OK. This action will
load the part linkage bracket from the file
KEYCREATOR_tutorial_mm.CKD.
CPLANE axes
WORLD axes
Once you’ve loaded the part your display should show the geometry seen above. Notice the axis
indicators in the lower left and upper right of the drawing area. For this tutorial, you’ll be using
construction plane (CPLANE) coordinates for all of the modeling operations. Think of the
CPLANE as the current working plane. You can change the orientation of these axes at any time.
Modeling operations that are plane dependent will take place with respect to the XY plane of the
current CPLANE axes.
STEP 3 Toggle the display of a level
The part that you’ve loaded is displaying both wireframe geometry and dimensions.
KEYCREATOR uses levels to organize data. The dimensions and wireframe data have been
created on separate levels. Turn off the display of the level that contains the dimensions. To do
that choose VIEW>CONTROL BARS>TOGGLE PART SPLITTER to open the level list. Right-
click on the level named DIMENSIONS and choose DISPLAYED from the pull down menu. The
dimensions should no longer be displayed. Choose VIEW>CONTROL BARS>TOGGLE PART
SPLITTER to close the level list.
Step 4 Create a solid model for the linkage bracket
Next, Use the wireframe geometry to generate two extruded solids. Start by setting the CPLANE.
Change to the TOP CPLANE by using the hot-key combination CTRL+1. Next, set the QUICK
CHAIN selection function by choosing EDIT>SYSTEM SETTINGS>QUICK CHAIN from the pull-
down menus. To invoke the EXTRUDE command use the hot-keys SHIFT+E. An icon pallet will
pop-up under the cursor. Use the tool tips (at the bottom of the interface) to help you select the
EXTRUDE icon. In the EXTRUDE dialog box, choose the options shown above. Click OK. On the
conversation bar, you’ll see a number of selection options and you’ll be prompted to Select the
closed planar curved profile(s). Choose CHAIN as the selection method.

direction
Since you’ve turned on QUICK CHAIN earlier, simply place the cursor near the “U” shaped profile
to highlight it (QUICK CHAIN automates the chain selection process). Left click to select the
profile. Once the profile is selected, right click to ACCEPT the profile. To complete the EXTRUDE
you’ll need to select the extrusion vector. Move the cursor near the vector as shown above. You
can toggle the vector by moving the cursor. Toggle the vector to the upward position and left
click. Once the solid is created, choose ESC to exit the command. Use SHIFT+5 to render and
view the newly created solid. Change back to wireframe display for the next operation by using
SHIFT+1.
Selection polygon
To form the final shape of the bracket, you’ll need to generate a second extruded solid. Change
the CPLANE using CTRL+2. Use SHIFT+E and choose the EXTRUDE ICON. The settings in the
dialog will remain the same as for the previous extrusion. Choose OK. On the conversation bar
choose POLYGON as the selection method. Use cursor and left click to generate a polygon
around the second profile as shown above (be sure to generate the polygon as closely to the
polygon above as possible so that unwanted entities will not be selected). If you make a mistake
simply choose ESC to exit the command and start over. Choose ACCEPT to close the polygon,
then, ACCEPT to complete the selection. Use the cursor to toggle the extrusion vector and left
click to complete the extrusion. Use SHIFT+5 to render and view the newly created solid. You
can use CTRL+Z at any time to UNDO an operation and try again.
