Project 1 - 2D meshing on the instrumental Panel
Aim :- For the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned.
Write a detailed report on your meshing process and also mention which method you used to extract the mid-surface along with the reason.

Procedure :-
Step 1 :-Import model .
File - open - select the file - import.
Step 2 :- Topo the given model
Topo -topo -select the whole surface -topo.
Step 3 :- Geometrical checkup.
Checks -geometry -execute.
Step 4 :- Measuring the distance{thickness} .
Measure -nodes-select two nodes.
Step 5 :- Generating the midsurface.
1}
* Offset :-
Topo -offset -faces -select the surface - offset -give the offset value -offset.
giving offset value .
2}
* Taking mid curve.
topo -curves -middle -select line -ok.
* Project the curve as cut.
topo -cons -project -selelct the curve -select the surface -ok.
* create a new surface with curve and the line .
topo - faces -new -coons -selelc the curve and cut -create.
3}
Create a mid curve .
topo -curves -middle -select line -ok.
Created a middle curve.
* extrude the line .
topo -surfaces =extrude -extrude =selelct the line 
giving vector direction .
Created surface.
Step 4 :- Changing the orinetataion.
topo - faces -orient -select -selelct the surface -ok.
changed orient.
Step 5 :- Geometrical cleanup.
*Extending the surfaces.
topo - faces -extend -select the line -select the surface want to extend.
Extended Surfaces,
*Deleting the penitration surfaces.
Intersect the sutfaces.
Topo -faces -intersect -select the surface -one after another.
Deleted surfaces .
After cleaninguping the geometry .
Step 6 :- Assigning Mesh parameters .
Step 7 :- Assigng the quality criteria .
Clearing the geometry .
BY Joining the lines .
Creating mid line due to minimum length failure .
Created a middle curve .
project the curve as a cut and defeature the line s which is failing,
Step 8 :- Generating Mesh .
Classic mesh - mesh generation - best -select the surface - mesh .
Step 9 :- Spliting tria.
Classic mesh -element - split .
Step 10 :- Smoothing
Classic mesh -shell mesh -smoothing.
Step 11:- Pasting the nodes.
Classic -grids -paste .
After meshing Completion .
Step 12 :- Assigning property and thickness to the material.
Classsic mesh -macro - nSet PID
Assigned thickness.
Assigned thickness to all part.
Step 13:- 2D Reprensation.
Quality Criteria - Presentation parameters -Turn on - Draw shell as solid
2D -Reprensentation.
Some element failure is there due to triple cons.
Due to that there are some off elements are there
Final Model :-
Result :-Meshed the given model with given quality criteria and assigned thickness to the component.
Learning Outcomes :-
*Learned about different types to create mid surface .
*Learned about geometrical clean up.
*Learned about to resolve the geometry failures.
*learned to assigning thickness to different component.
