Using This Guide

Using This Guide
This User's Guide is intended for users who needs to become quickly familiar with the
Generative Drafting Version 5 product.
Before reading it, the user should be familiar with basic Version 5 concepts such as
document windows, standard and view toolbars.
To get the most out of this guide, we suggest you start reading and performing the step-bystep tutorial Getting Started. This tutorial will show you how to define a drawing sheet and
create views from a 3D part.
Once you have finished, you should move on to the next sections where you will find
detailed explanations regarding the handling of drawing and sheets, view creation and
modification, dimension generation, etc. You can also take a look at the Workbench
Description section describing the Generative Drafting workbench.
To perform the scenarios, you will use sample documents contained in the C:\Program Files
\Dassault Systemes\Bxxdoc\English\online\cfysa\samples\Drafting folder (where xx in
Bxxdoc stands for the current release number). For more information on accessing sample

documents, refer to Accessing Sample Documents in the Infrastructure User's Guide.

What's New

What's New?
New Functionalities
Locating reference/resulting views
Two new contextual commands now let you navigate easily between reference/
resulting views in the case of section views, section cuts, auxiliary views or detail
views.
The Locate Reference View command reframes the drawing viewer on the reference (i.
e. parent) view of a section view, section cut, auxiliary view or detail view.
The Locate Resulting View command, available in the contextual menu of a callout,
reframes on the resulting (i.e. child) section view, section cut, auxiliary view or detail
view.

Aligned section view and section cut, offset section view and section cut
You can now generate aligned section views, aligned section cuts, offset section views
and offset section cuts as defined in the Functional Tolerancing and Annotation
workbench.
DXF import and export
New and enhanced functionalities are available regarding DXF import and export.
These functionalities are documented in the Data Exchange Interface User's Guide.

Enhanced Functionalities
View from 3D
Hidden geometry management
Extracted annotations attached to geometry that is not displayed in 2D views are now
highlighted.
2D ditto Note Object Attribute extraction
2D ditto Note Object Attributes are now generated in views from 3D.

Generative View Styles
3D properties inheritance of projected geometry
Using generative view styles, you can now apply 3D linetype, thickness & color to
projected geometry (wireframe, solid, 3D points).
Importing a newer version of a generative view style file
You can now import a newer version of a generative view style into a drawing. Doing
this will completely override the older version of the generative view style in all views
which use this generative view style. This functionality is particularly useful if you
created views in V5 R11 using the generative view styles provided by default with the
application, and want to benefit from the new styles parameters that were added in
(1 of 2)10/19/2004 5:46:23 PM


What's New

V5 R12.

Miscellaneous
Dimension generation on Part Design user-defined feature
You can now generate dimensions from Part Design user-defined features.
Thread ASME/ISO Fractional representation
A fractional dimension will now be generated for threads/taps defined in a 3D part
(Part Design) which use standards with fraction as a symbolic representation (e.g.
G1/8).

Customizing Settings
View generation in Approximate mode
You can now generate views in Approximate mode. This generation mode is
particularly well-adapted to large assemblies as memory consumption is dramatically
reduced and performances are improved.
View generation in raster mode
When generating views in raster mode, you can now add shading or shading with
edges, as well as use dynamic hidden line removal. You can also choose between
three pre-defined and a custom mode to set the level of detail that will be used to
visualize and to print the drawing.

Getting Started

Getting Started
Before getting into the detailed instructions for using Generative Drafting, the following
tutorial aims at giving you a feel of what you can do with the product. It provides a step-bystep scenario showing you how to use key functionalities. The main tasks covered in this

section are the following:
Defining the Drawing Sheet
Opening a Part
Creating a Front View
Creating a Projection View
Creating a Section View
Creating a Detail View
Creating a Section Cut

Before you begin, make sure you customize the following settings:
Grid:
De-activate the Grid icon

from the Tools toolbar (bottom right).

View names and scaling factors:
Go to Tools->Options (Mechanical Design -> Drafting option at the left of the
dialog box, Layout tab) and un-check the View name and Scaling factor options.

This step-by-step scenario introduces the basic capabilities of Generative Drafting.
You just need to follow the instructions as you progress along.
At the end of this getting started, you will be able to print the following sheet:

Getting Started

Before discovering this scenario, you should be familiar with the basic commands
common to all workbenches. These are described in the Infrastructure User's Guide.

Defining the Drawing Sheet

Defining the Drawing Sheet
This task shows you how to define the drawing sheet to be used for creating the
views described in further tasks.

1.

Click the New icon

from the Standard toolbar or select File -> New... from

the menu bar.

2.

Select Drawing from the List of Types and click OK.

3.

From the New Drawing dialog box, select the
ISO standard, and the A0 ISO format.
In this particular case, and all along the guide,
we use the ISO standard.

(1 of 2)10/20/2004 5:05:18 PM

Defining the Drawing Sheet

You can add an unlimited number of customized standards using Standard files
that you will create and/or, if needed, modify. Once created, this standard will
appear in the New Drawing dialog box. For more details on standards, see the
Standards Administration section. Care that any user-defined standard is based
on one of the four international standards (ANSI, ISO, ASME or JIS) as far as
basic parameters are concerned.

4.

Click OK.

5.

In the Generative Drafting workbench, a grid is set by default. Throughout this
documentation, we decided not to display the grid. To do this, de-activate the
from the Tools toolbar (bottom right).
Grid icon
The drawing sheet appears as shown here:

From now on, you will work on the created sheet unless you define a new sheet.

Opening a Part

Opening a Part
This task will show you how to open the part to be used in the Generative Drafting
workbench to create views. You may use either a 3D part or an assembly.

Before you begin and all along the current Getting Started chapter, make sure you
customize the following settings:
Grid:
De-activate the Grid icon

1. Click the Open icon

from the Tools toolbar (bottom right).

from the Standard toolbar or select File->Open... from

the menu bar.

The File Selection dialog box appears.
2. Select the part to be opened. In this example, the user selects the
GenDrafting_part.CATPart document.

Opening a Part

3. Click Open. The part is opened and will remain displayed in the window whatever
the views you will create from this part.

Creating a Front View

Creating a Front View
This task will show you how to create a front view on the sheet previously defined and from the 3D part you
previously opened.

At this step, we strongly advise that you tile screen horizontally . For this, go to Window -> Tile Horizontally
options from the menu bar.

If you do not want to have the specification tree displayed, press the F3 key.

1. Click the Drawing window, and click the Front View icon
the Views toolbar (Projections sub-toolbar).

from

Creating a Front View

2. Select the desired planar surface of the 3D part you opened, from
the 3D Part viewer.

Blue arrows and a green frame including a preview of the view to be created appear on the sheet.
These frame and arrows let you define the location and orientation of the view to be created. As long as you see
the green frame, you can define the frame position using the blue manipulators: top, bottom, left, right or rotated
according to a given snapping, or else according to an edited rotation angle.

3. Click on the drawing sheet or at the center of the blue manipulator
to generate the view.
The front view is created.

In the Generative Drafting workbench, the view name, scaling factor
and view frame are set by default. Throughout this documentation,
we decided not to display view names and scaling factors.
