Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

A simple excercise on flattening of 3D harness.   Different Harness Flatening features could not be appliedhere due to the design constraints of this simple wire harness. How we did the Drawing from the 3D harness. We first extracted the product file in Harness Flatening Product filen and flattened it. We can rotate…

 WEEK 5 & 6 Snap of Electrical connectivity False command. Theres no bundle that is electircally disconnected Method of doing the same was rectifiedusing Video instructions. Snap of Electrical connectivity True command. These are the bundles that electircally connected Annotatioins. Method of doing the same was…

Connectors and electrical Definations.   Assembly The Distance have shorten as the Coverings are kept away from extreme points. I found it little difficult to arrange connectors on a same plane with angle at specific distance. I have used my approach to do this challenge. Let me know the mistakes. Couldnt make any…

Q1. P Clamp Defination Procedure. Get the CAD part. Define the geometrical Parameters. Define as Support. Define entry andexit pointsand plane. Define Base plane. In electrical Part Design we declare it as clipusing Define Support Part. We need to select the point and planes accordingly.     Q2. Backshell CAD…

I created Catalog and browsed it to get the same CAD files in a Electrical Part Design. This we get after adding CAD files in Catalog. Connector defination in Catia v5 Deutsch DT06 – 08SA First we see what are the faces that are goingto connect to a Bundle harness and other connector. Accordingly we give the electrical…

    Used various constraints options to make the assembly.  Mostly it was aligning with axis and surface  touch. Here during GD&T we learnt a new concept of having axial relations when we have axial features. Report will have same basic explanation of what tolerances were given. No new approach…

CAR BACK DOOR DESIGN by SAHIL PARAB Aim: To design back door of car using given outer class 'A' surface using SiemensNX. What is back door of a car? A door which is located at the rear side of a car which gives access for the boot space to store luggage, spare wheel etc. These doors can be operated manually or electric…

Roof Analysis and constructional Study by Sahil Parab   OBJECTIVE : The objective of this project is to design car roof with  essential flanges and reinforcements  like ditch area , front roof rail , bow roofs, central roof rail and rear roof rail for the the given styling surface Perform a curvature study…

FENDER: Fender is the part of an automobile, motor cycle or a vechile body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road sprayfrom being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with…

Wheel Arch Calculations From:Sahil ParabAim :     To calculate the wheel arch gap at required points and check whether the car passes the European standard.Objective :Study about the different wheel arch gap standards.Check the feasibility for the European standard.Measure the distance at each angles…

  SECTION MODULUS OF AN HOOD Section modulus is a direct measure of strength of any  sectional area of an object about an reference axis(neutral axis). Strength is nothing but, capable of supporting greater loads, so higher the strength it has a high capable of supporting  greater loads. This strength…

Hood Design Report.   Initially we got the hood outer panel surface. According to the instructions and requirememnts , we offset the surface and created the inner surface to apply emboss and other features. Spiltted the surface and worked on it entirely to mirror and avoid doing things twice. Gave emboss and Mastic…

On multiple TSE sessions , as I was told to approach the project from Making the CAD part first followed by Engineering features and finally Flanges. Followed the same. As Im a working professional , I tried my best to complete the same with least time . Few equipment  breakdowns happened at work so took more than…

In this report of Sahil Parab , we will know about what is Underbody coating , what are its advantages and disadvangtages and why it is important to do underbody coating.   What is Under body coating? Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the…

In this report by Sahil Parab, we will look What is Benchmarking and how and why it is used by industries. We will also see an example to understand this practice.   WHAT IS BENCHMARKING ? It is the process of comparing one's business process and performance metrics to industry's best practices from other industries. Process…

C What did I do. Created parts using part design as I got them ready faster. Published Axis and planes that will help me Assemble/join/Form an assembly. Individually opened files in Product and declared an empty plane and point. Using axis and surface, coincided ,offsetted different parts accodring to the requirement to…

What is Sketch solving status's geometry tab? I hvae attached everything i could understand.

Need more practice for cleanliness and asthetics. Height  of Locators kept higher than heat stacks. I have created 1 4way and 1 2way locator.  Dog house dimensions became little small. Draft analysis on solid surface gave little red surfaces dew to few angular deviations. Draft analysis on final Component with…

Draft analysis show few faces not as per given angles. If we reduce the angle it gets green. Draft analysis on final solid gives detail knowledge of anguler changes on outer and inner surfaces. Tooling axis and side core axis were used for giving draft of the dog house faces. Side core draft:0.5 Main faces draft:3

  Draft Analysis on Class A DA on Final solid Part     Draft Analysis on Class A clearified there is some error in class A itself. However when performed on Solid part we found the error was seen on sweep surfacein very few areas. When angle was reduced to 2.5-2.8 the error got eliminated. Draft angle was…

Draft Analysis were performed on Class C and Solid component. We saw the red surfaces on verticle and those surfaces which has angle deviation less than 3degrees. Upon reducing the angle constraint to < 3degrees , we see the red colour goes which meant the deviation is less than 3 on these surfaces. I had sweeped them…

Draft Analysis in class A case was done and found the surface do not have any more than 3degree deviation.  Part design had blue surface below as theres no draft applied there.   tooling axis inthis case was found to be on number plate as maximum parts were visible when viewed perpendicular to that plane.  …

Draft Analysis: When I performed draft analysis on class A , I saw everything green which meant the degree was 3 or more.  I have arranged a session wrt to thorough Draft Analysis explanation. As of now the blue areas gives me indication that the surface has <3degree surface. Helps in understanding the angular…

    Tooling axis in this case was done by bisecting two dummy axis. First we take bisection of the class A surface using XY plane and get a dummy axis.Then we try to get a intersection of the same using XZ plane. From this we create a coincident line and a 3degree angled dummy axis 2.  We bisect this two…

Draft Analysis : Helps us get draft angle and measurements. In some cases we have to untrim extracted sections and get the same Insert – Analysis – Feature Draft Analysis Draft analysis was carried out by pulling the compass to the tooling axis and an inverse draft axis was carried out if required. After setting…
