Advanced CAD - Project 1 (GRAP2029) Pump Bottle


For our first project this year we had to reverse engineer a Dettol soap bottle. We started by disassembling the bottle into its individual components and then measuring/recreating them in Solidworks. (we also had to make a wine bottle just as a refresher)

This is what happens when you try to mirror a sketch instead of a feature


For my pump assembly I decided to try something new, in context modeling, I accidentally put a sketch in the assembly instead of the part I was trying to make and this caused me many errors along the way. The sketch was not useless as I was able to just convert entities into my part sketch but definitely something I will avoid in the future.

After I mirrored the two bodies I had created and started to work on the top of my bottle I saw that the loft profiles were giving me strange curves causing my bottle to have issues, changing the profiles gave me even more problems. Going through one by one was the only way to fix these problems.



I had this little pinch cased by the loft points not lining up just right, this was fixed by putting in a plane and making sure that the points were at an equal height this solved the problem and resulted in a really nice bottle.


After I had created all my parts it was time to mate them and because I made some reference dimensions to the wrong parts I ran into issues, I had to go back and edit the sketches so that they would not be thrown out of proportion when other parts were moved. Next time this wont be a problem.


For my first time using in context modeling I really did learn a lot and it is definitely something that I will be using more, even though I ran into tons of problems these are things that wont happen next time round. I found out that you can easily group parts to form sub assemblies within the assembly which is very convenient.
