proe setting and common practice

Title: ProE Setting and Common Practice

Objective:

This document contains the OC common ProE setting. This is to enable the CAD be efficiently review/reused.

For:All OC ProE user

Instruction:

Sentences in bold red are compulsory requirements for all projects, unless approved by the project supervisor.

ProE Setting and Common Practice

The ProE folder


Storing external Data like ID master, PCBA, Mechanism etc

Storing Drawing format, symbols, note etc

Storing old ProE files that no longer in use, before permanently delete. This folder is not in the search path

ProE setting file

Screen customization file

File purging. One copy is in the PART, ASSEMBLY and DRAWING folder

Image file for texture

The ProE/FORMAT folder


Storing Drawing format, symbols, note etc

The Colour and Appearance templete

Default Part and Assembly template

Part and Assembly template for OSD project. The config.pro need to change accordingly

Drawing setting file

Model tree setting file

The ProE UI


Screen changing mapkey Analysis tool bar

Datum tool bar

Feature tool bar

Filter

Model tree (orca-tree.cfg

setting)

The Default part and OSD project part


The Default part1. Relative accuracy (default 0.012)2. The default orientation as below:

The OSD project part1. Absolute accuracy (1e-4)2. The default orientation as below:

Changing accuracy will cause feature fail. The default part and assembly template need to set correctly from the start.

Top Down Design


XXXX_id_master

XXXX_layout

merge

merge

XXXX_case_top

For complex assembly, use id master and layout to merge to the case part. The layout file should have important datum like the datum plane “PCB”, which will be the bottom surface of the PCB.

For simple assembly without mechanism, the feature in layout can be build in id master, and part only need to merge the id master.

The id master and layout should have specific layer control. Unnecessary layer should be avoided because all layer will be inherited by the part and crowd the layer window.

The file structure


XXXX_main_assy.asmXXXX_PCB.asmXXXX_PCB.prtXXXX_case_top.prtXXXX_case_bottom.prtXXXX_screw_mc_M2x6.prtXXXX_screw_st_M2x6.prtXXXX_bracket_pcb.prtXXXX_printmech.asm

1. The naming scheme is: XXXX_type_function/position2. All internal designed part and assembly must have XXXX in front.3. All external designed assembly must be assembly to a packaged assembly (e.g.

XXXX_printmech). The packaged assembly will then be assembled to XXXX_main_assy by default location.

4. ID master should not be assembled to main assy.5. Do not assemble reference component to the module assembly. E.g. the scanner assembly

should not have printer case part. The referencing should be done in separate assembly file.6. All screw and other fastener need to assembled.

The external CAD


1. The external CAD should be converted and named properly before assembled into main assy.2. The external CAD should be placed in folder with date code e.g. PROE\EXT\DUPLEXER\0911173. The config.pro should add the search path.4. When there is updated external CAD, it should be named properly and placed into folder with new

date code.5. The config.pro search path should be change accordingly. Make sure that the old search path is

deleted to avoid data mixed up.

Main assy

8021_duplexer. Assembled default to main assy. This file name is permanent

091117_saipan_duplexer. Assembly created to import external data. Assembled default or using TFR

File name created automatically with CAD import. Change name like asm00001 or prt00001 to date code

The PCB


1. The XXXX_PCB.prt must be bare PCB without component.2. The XXXX_PCB.prt should be created in default position whenever possible3. All component must be assembled relative to the XXXX_PCB.prt4. The component should have curve indicating the pads and holes layout. PCB should cut

holes by refer to the curve at assembly level

Layer


All curve (important curve can be stored at other layer)

The GDT datum and feature control frame

The curve, datum, quilts and datum TFR from id master. These layer is inherited from id master

All datum (important datum like TRF can be stored at other layer)

The curve, datum, quilts and datum TFR from layout. These layer is inherited from layout

All quilt (important quilt like pivot can be stored at other layer)

The View Manager – x-section


V0

H0

V0 – xsection across dtm RightV1, V2,… - xsection parallel to dtm RightH0 - xsection across dtm Front/TopH1, H2,… - xsection parallel to dtm F/T

The View Manager – Simp Rep and Style


Simp Rep:1. Unit – have only the component

in shipping condition2. Case_part – have only case part3. Interference - For global

interference checking

Style:

The name indicate the component that is shown in wireframe

Draft Analysis

Each plastic part should have the following draft analysis saved for regular checking:1. DRAFT_1: 1 degree both side, mold direction2. DRAFT_3: 3 degree both side, mold direction3. DRAFT_S1: 1 degree both side, slider/lifter direction


Analysis name

Select “SolidGeom”

Select “both side”

Modeling Best Practice


1. Do not create relation in the assembly. Part must only refer to id master and layout. Exception is PCB which refer to component and case part to create holes and keep out area

2. Do not mirror feature. Mirror of surface is permitted.3. Do not use “hole”, “rib” and advanced feature like “lip” and “slot”. The normal protrusion is

more flexible and robust.4. Put “draft”, “round” and “chamfer” at the end of the model tree. Do not scatter around.5. If a new datum is needed for sketch plan, it should be created “on the fly”. The sketch also

should be embedded into the feature whenever possible

Modeling Best Practice (sketch)


1. During sketch plan setup, use “top” or “front” as top.2. Use TFR as reference in most cases.3. Use PCB as reference for PCB related feature.4. Use surface as reference instead of line.5. Dimension the sketch according to the design intend.6. Use minimum dimension and use more relation.7. Do not leave weak dimension in the sketch.8. Do not use dimension with decimal point more then 2 unless necessary.9. Do not use edge for circle. Should take reference of the cylinder surface and create concentric

circle with equal dimension to the reference.10. Use centerline to locate feature unless the side wall is the functional surface. This will enable

the counterpart using the same dimension scheme.
