Setting the Drawing Sheet Format and Drafting Standards

The Modify option changes the default sheet format and the format standards.

The following items maybe set: ISO, ANSI and JIS standards Paper formats (A, B, C, or A0, A1, A2, etc..) Orientation (Landscape or Portrait) Sheet scale (1 is default and should only be changed with caution)

ISOANSIor JIS

Format settings can be modified later if necessary: for example the paperorientation or size with menu File + Page Setup...

Select the option to create projection views using the thirdangle projection standard

3 Select OK to accept thechanges

After changing the Sheet properties to the third angleprojection standard, set the sheet as the default so all othersheets will be created with the same angle of projection.

Views can be associative (linked to 3D parts) or unassociative (unlinkedfrom a 3D part).

Associative (Linked) Views to a 3D part are called GENERATED VIEWS .

Unassociative (Unlinked) Views to a 3D part are called DRAW VIEWS .

What are the different types of Sections Views ?

Simple offset section - a full section with a simple single cutting plane fully passingthrough the part

Complex offset section - a full section in which the cutting plane is offset to passthrough important features Complex Offset Section

Offset Sections

Simple Offset Section

Aligned Sections

Aligned sections, also called "revolved" sections, has a cuttingplane revolving around an axis

There are 3 main types of sectional views; "full section", "offset" or "aligned" dependingon how the cutting plane is defined.

Section Views and Section Cuts


37/148


Section View: A view of the cutting plane and any geometrythat extends beyond the cutting plane in the direction of thesight (arrows).

Section Cut : A view of only the material thatthe cutting edge touches when passingthrough the part.

Reminder of the differences of a section view (Offset or Aligned) and section cut (Offset or Aligned)

What are secondary Views ? (2/2)


42/148


Secondary Views:

5) Breakout Views : A breakout view allows thecreation of a local cut (by a plane) in order to see theinside of a part without cutting it totally.

6) Auxiliary Views : An auxiliary view is a viewcreated in a given direction which is not a directionthat can be obtained with a standard view

7) Unfolded Views : An Unfolded view is a view thatcan only be obtained from a Sheet Metal part. Thiskind of view unfolds the sheet metal part inaccordance with the rules which have been appliedto the bends

Detail Views Types


43/148


Detail views can be full detail views that are calculated from the 3D part or "quick" detail viewsthat are calculated from the defining 2D projection of the view. Both types of detail views canbe defined by a callout using a circular perimeter or a profile perimeter.

1 Full Detail: The geometry for the view is calculated from the 3D

part with a boolean operation of the callouts perimeter.

Circular Callout

Profile Callout

Quick Detail: The geometry for the view iscalculated from the 2D projection of the view.

What are Generated Dimensions ?Generated dimension are dimensions that are created from existing 3D Part constraints

Sketcher constraints


95/148


Pad Definition constraints

The dimensions that are generated from the 3D part aredetermined from the filter settings in the drafting options.

Ways to Generate Dimensions

Dimensions can be generated with two different methods


96/148


1- In One Step

2- Step by stepFor each one you need to set up options

Dimension Generat ion optio ns are set on the Generat ion Tab within t he draft ingopt ions .

One Step Dimensioning Options


97/148


Dimension Generation filter option allows you to choose what type of 3Dconstraints will be included in the generation of dimensions. It isrecommended to have this setting on to assure desired dimensions aregenerated.

The allow automatic transfer between views only applieswhen using the step by step method.

The analysis after generation provides valuable information on theconstraints found and the constraints generated.

The Filter before generation option allows the selection ofdesired views for the dimensions to be generated into.

The step by step opt ion s al low you to c ontrol the generat ion and mo dify thedimens ions one by o ne as the are visual ized.

Dimensions are generated in the selected views. If none of the viewsare selected the dimensions will generate is the most appropriate viewsuch that they will not have to be dimensioned anywhere else.

4

Constraints can be recovered by selectingthe Excluded constraints Icon and theconstraint to be recover from 3D geometry.

Often when Dim ensions are generated in one s tep they require reposi t ion ing. Theautomatic pos i t ioning o ption does this op erat ion in one s tep.

Dimension Interference can be analyzed if the dimensionshave been Generated from 3D or Manually created.

The analyze panel provides the following:

Dimension Interference Analysis

(A) Interfering Dimension list:The interfering dimensions can be viewed as a whole list or a filtered to display anoptimized list

(B) Total number of elements in the current list:As Dimensions are relocated the update switch will correct the total number of

dimensions that are poorly placed

(C) Number of the pointed element:

Each dimension that has an interference is assigned a number and this fielddisplays the number of the elements currently pointed at as an interfering element

Example results: Arrange the balloons asneeded after creation. Youcan also change the Fontproperties of the balloons asneeded.

To change the instance number, activate theCATProduct properties of the desired part andmodify the instance number.

If one parent element of the dimension is deleted or deactivated, as soon as you update the drawing(either 3D Generative or 2D Interactive drawing), the orphan dimension becomes purple on thecondition you activated the Analysis Display Mode

Dimension Associativity


106/148


Update ( )the drawing inaccordance with the 3D, any nonassociative dimension willdisappear.

Colors can be customized using the Analysis DisplayMode option from the Tools toolbar or via Tools-+Options (Drafting option to the left of the dialog box,Dimension tab).
