Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

Draft analysis of the class A surface

                                                                       

                                                       

draft analysis of final component

 

draft analysis of class a from different orientation

      

Tooling axis and Draft analysis reprot

• when i tried to draw the tooling axis using the various faces then i get to know the the some patches will left in it as it does not get cleared any of the tooling axis wheather i will use the bisecting method or i will use the normal to surface method. So i selected the tooling axis where the minimum pacthes are visible according to me. Also i verified it with my superior too. 
• So in the class A surface itself the draft is not given at some places. 
• So the above line is the Tooling axis i selected.

Draft analysis reprot of the final component with the ribs and the screw boss

• when i draft analysis the final component along the tooliong axis here i get to know that the some pacthes will let. 
• when i asked the same from superiors they told me that these surface vertical to the tooling axis thats why they will show like this so keep it as it is. 
• also when i use the pointer then i get to know that the pointer is showing angle more then that of 3 degree angle but in opposite direction. So at some places the draft angle is ok. 

Now ab out the ribs and screw boss:-

• when i performt he draft analysis of the final component along with the screw boss and the rib then it will show in red color but when i use the pointer it show anlge 0.5 which is correcgt which means i have given the correct draft angle to ribs and screw bosses but these are not clearing the draft anlysis in my version of catia. '
• Then i asked the techincal support engineer about the same then he told me that this thing occuring due to your catia version. Also i mailed him this 3d model which i have prepared and he was having the 2022 version of catia and when he perform the draft analysis then ribs and screw boss clears the draft analysis where the draft angle was 0.5 degree according to the screw boss and ribs design rules.

NOTE:-

Also in my catia version i cannot intersect the whole body including ribs and screw bossed with the axis system which i have defined. So unable to perform the rib root analysis. but i know how to performt that. Then the technical support expert told me to submit it as it is.
