Week 5 Challenge : Surface wrap on Automotive Assembly
AIM
For the given models, check for the geometrical errors and delete surfaces which are unwanted for Surface wrap. After clearing geometry, Merge all 3 models and perform surface wrap.
Target length for Wrap = 3 mm
PROCEDURE
Open the engine model first
Directly delete the surface that are not attached to engine which is clearly visible
For this challenge we have to delete unnecessary tube that the designer has made in order to make fillet between 2 surfaces and no need to clear single or triple cons inside the engine.
We can directly delete the unchecked surfaces by right clicking on it and use universal delete option to delete it. It is better to delete unchecked surfaces, we don't want to bother whether it is outside or inside the engine.
Now, use F1 to F6 to see the model from 6 views and hide the necessary engine parts to delete the unnecessary tubes and small surfaces.
Use F1 now
Hide all the necessary engine parts by using Not in PID feature
Similarly use F2 to F6 to hide necessary engine parts
Now, the isometric view of the unnecessary part looks like this. We can use Undelete option to bring back any necessary surfaces if we delete it.
Use delete option now to all together delete this surfaces.These tubes and pipes are intersecting and we don't need it.
We can use Undelete option to bring back any necessary surfaces if we delete it.
Now, the engine part looks like this
Delete the tubes outside that we missed to delete.
We can delete the belt because it is of small thickness which is not suitable for surface wrapping.
After all the model looks like this.
Clear all triple cons, single cons and geometrical errors that are visible from outside.
After that we can close the holes in the model to make it suitable for surface wrapping.
Use F1 to F6 to see each surface and then fill hole.
After filling the holes, lets move to transmission part to clear the errors outside
Delete unchecked surfaces
This is one of the main part to clear triple cons in this geometry
After that merge with engine
Then close the remaining holes
Now, clear the errors for gear box
After clearing triple cons or single cons from outside, merge it with previous file and then fill the remaining hole. Then the model looks like this
Use wire frame mode to see any single cons or triple cons and then zoom to see whether any error at outside surface.
Now lets do compress to compress the unnecessary PIDs
After compress, there is only 112 PIDs
After that lets go for surface wrapping.
Select constant length wrap from octree
After that assign 112 PIDs to wrap
Then provide the target length as 3 mm
Click on run to do surface wrap
After surface wrapping, the model looks like this shown below

CONCLUSION
The surface wrapping is done with target length of 3 mm
