Before this, I already join Coursera online course refer to my last post, but only manage to learn from video and doing an assessment with getting online certificate. the cost to get an online certificate is 49USD or 200++MYR. this course is given for those who are unemployed to gain new skills. I am trying to learn new skills and update each of the skills in this blog.

Online Course

  

Just want to sharing my activities that I discover during early of pandemic stage. Join online course. I learn all this course from Coursera website. Due to lockdown during early of pandemic in March. Currently, I already resign from my job due to pursue my study to Master degree. So, I decide to continue this blog to write and put any skill I learn, and write this blog in english to enhance my grammar and vocabulary. So, please excuse my english because it is still far from proficiency level. 

Assembly Design

Slider Crack Mechanism

Finally, dapat juga belajar assembly design. Credit to this pdf https://static.sdcpublications.com/pdfsample/978-1-58503-762-9-4.pdf . Kat sini dia ajar buat dari part design ke graphic graph. Tu dari avi tapi aku convert gif so dia boleh play non-stop.

Base

Block

Conrod

Crack

First of course kena buat part design dulu. Ada 4 part kena buat base, block, conrod and crack. Empat part nie boleh buat dekat part design. Dimension dia bagi sekali. Cuma aku ada adjust dimension dari yang tutorial tu. Sebab mungkin tutorial tu pakai inch tapi aku punya pakai mm. Malas nak tukar.

Ada several step and command yang kena guna kat assemble design workbench.

Existing Component = nak insert semua part yang dah di-design dalam satu workbench

Manipulation (Move toolbar) = nak gerakkan part tu. Asingkan part so that dia tak bertindan satu tempat.

Constraints toolbar

- Fix = Nak bagi base tu stick satu tempat

- Coincidence = To select which axis nak satukan sekali

- Contact = Nak gerakkan automatic kat tempat nak disambungkan.

DIGITAL MOCKUP - Kat workbench nie nak simulated design tu. Boleh adjust speed dan save dalam format AVI video.

Last but not least, nak view motion graph.

Some exercise getting tough and hard. Lama-lama, hari-hari buat catia nie dari saja-saja nak try explore main-main. Baru aku sedar dia buat otak aku berfikir dan kreatif macam mana nak solve kat design nie macam yang dia bagi ikut dimension yang sama. Walaupun mungkin ada setengah part yang tak perfect dan terlepas pandang. Bagus gak untuk otak aku dari tepu je tak fikir apa-apa.

Body Swatch & KLCC

Body swatch

Semalam terjumpa tutorial pdf nie. https://dokumen.tips/documents/catia-tutorialpdf.html. Semua lengkap dia ajar satu persatu dalam pdf tu. Kat situ ada tutorial untuk assembly design sekali. Dah lama cari tutorial assembly design yang aku boleh faham cara dia ajar. So untuk buat part design aku ikutlah dia punya guidelines kat pdf tu. Untuk assembly design pon ada, dan untuk assemble Swatch nie kena tambah ring, button, bracket design part tu sendiri. Selepas design sendiri part tu, aku stuck bila nak assemble semua part nak satukan jadi product. So lepas nie kena try redo balik semua part tu and try again.

KLCC

Sebenarnya dah lama dah berangan nak design KLCC nie. Nie aku just tiru geometry bawah tu je. Tapi dimension semua pakai buat je. Macam kelakar pula bila dah settle. Sebenarnya nie belum settle betul lagi. Patutnya ada command lagi kena pakai nak bagi dia lagi smooth dan lama. Tapi disebabkan aku tak expert lagi, basic command pon masih terkial-kial tu yang output pon kelakar tu. Nie nak buat suka-suka je sekadar nak puaskan hati. Harap sangat ada guidelines nak buat KLCC nie.

Model 3

Kadang-kadang terfikir bila nak start challenge diri belajar create model yang susah.

Sketcher Exercise

Sketcher 1

Sketcher 2

Sketcher 3

Sketcher 4

Nie lah yang aku cakap spent berhari-hari nak buat tu. The reasons is sbb try hard sangat nak design sketch nie jadi 3d modelling. Tapi tak menjadi. So since kat buku tu dia dah kata sketcher exercise, so kita sketche jelah kot ikut dimension dia bagi.
