Is this an educational course or an advertisement for Autodesk? You will only experience and be told of Autodesk products: Sketchbook, Tinkercad, and Fusion 360. No other design programs are mentioned much less compared and contrasted. No mention of Illustrator (vs Sketchbook), OpenSCAD (vs Tinkercad) or Solidworks (vs Fusion 360). Set up in this manner, it shouldn't require a $79 Coursera fee given that this is setup to capture new students into Autodesk's product line. Meshmixer is an Autodesk product and oddly isn't even mentioned, despite being widely used in the 3D printing community.

The course is overly focused on free-flowing design. Despite being a 3D-design class made to be embedded in the 3D printing industry, you never have a video or assignment that has you make a part or item to specified measurements. This is a real gap in the teachings; I would argue to have replaced Week 4 on sculpting with a module on adding dimensions and locking relationships and measurements (lengths, angles) between parts and components.

The class instructor, Jeff Smith, has never responded to a forum post or question in the history of the class. The fifth week of class is taught by a student rather than industry expert and he is not given teaching credit. The sixth week is empty and is used to pad the course up to the 6-week, $79 fee scale.

Two weeks of focus on Fusion 360 is insufficient given the amount of content the instructor is teaching in the videos. For new modelers, a week on sculpting feels like too much; it's nice to make pretty shapes (starships/bicycle seats), but what about shapes needing defined precision? It would be great to learn to build two gears from scratch that turn with one another. If instructor disagrees with this philosophy, at the least it would be great to use sculpt tools to make a specific item with the sculpt having some sort of goal. Making free shapes is easier but less useful after taking this class. All or nearly all of the sculpted shapes you will make would be very, very difficult to print.

Time is wasted on learning rendering - after all, this class is focused on 3D printing, not sales or marketing (the reasons the instuctor gave for using rendering).

Additional issues are below:

Course is unorganized and outdated.

- Example 1: even though this is a recent class, the Autodesk product videos are outdated. The software used by the instructor is a different version with commands in different locations. This increases the difficulty in learning. For instance, in the Create menu, primatives have swapped places with basic functions.

-Example 2: 123D Catch is no longer a product that we can use - why is there still a video teaching this in the syllabus? Why hasn't this teaching been updated? This product was taken off market a year and a half ago and still the syllabus is outdated. In the text, they state for you to download software which is not free and requires purchase (Trnio for iOS).

- Example 3: in Week 3's videos, Smith demonstrates the bottom component being grounded, but not the top component. In the homework, we are instructed to take off points if the top component isn't grounded as well - all the other students I graded got this wrong (as did I).

- Example 4: in Week 3's assignment, it says it is worth 14% of the grade. However, the syllabus says it's worth 30% of the grade.

- Example 5: T-splines are discussed heavily in Week 4 but are never defined or explained. There is a glossary entry with a link to explain T-splines; the link has been invalid since January 2017. Even splines are not defined or explained, much less T-splines.

- Example 6: Material is presented out of order. For instance, the move triad is described in Week 4 but really needs to be introduced in Week 3 when you start using Fusion 360 for the first time.

- Example 7: Lack of organization adds to existing issues of current grading system. For example, the instructions for Week's assignment says, "For this first objective, you need to build a design that uses all 6 of the primitive tools, 5 times each (box, cylinder, torus, sphere, pipe)". We are instructed to use six different tools from a list of five tools. Some students grade for five, some for six, because of the inconsistency in our instructions.

- Example 8: Every submission for Week 4 I graded was flawed; the instructor has not taught students about resolving impossible geometries. All the submissions I graded were still stuck in Sculpt mode. When exiting Sculpt, Fusion 360 would identify impossible geometries, remove them, and leave the remaining items intact that do not violate topology. This means that no assignment I graded had the minimum number of shapes - if students thought they needed 12 shapes to grade, they would make 12, but 2-4 would be impossible. Since no student I graded understood this, I suggest this is a failing of the class/instructor.

Failure of student grading system, which adds to stress when paying for the class:

- Lack of student graders when turned in on time (see multitude of forum posts asking for previous week's assignments to be graded.) Typically, students not paying for the course do not volunteer to grade assignments.

- Some students are unable to open traditional graphic image files (e.g., TIFFs) in this 3D modeling class. They flag your submission which adds to the grading probem. Another student did not understand that to peer-grade assignments, he would need to be able to copy and paste URLs / site addresses (or as an excuse to not grade). There needs to be a prerequiste statement that students are expected to be able to use basic web tools and browsers, able to open typical graphic formats, etc. The instructor could help reduce this by allowing hyperlinks in all, not some, of the student answers.

- Your fellow students grading you are obviously not subject-matter experts and do not have any more expertise or experience than you do. Regardless, they grade your material and individuals will often misunderstand and score things incorrectly.

- If you have one of these issues, you're really on your own. You can post in the forum for help but neither the instructor nor Coursera will provide assistance.

good course for learning how to design a model for 3D printing. the teacher is teaching very clearly and good sort of knowledge is provided.

Very inspirational course but I need to research a lot on the internet in order to complete the exercises. The videos are barely helpful.

Interesante curso para iniciarte o complementar los conocimientos en el uso del software aplicado a la impresión 3D.

Week 1 is great, and I learned things that my criminally negligent arts teachers never bothered to cover. Weeks 2 and 3 start to show a decline that is hinted at in week 1, however: students seem unable or unwilling to count, and my grades depend on their ability, in some cases, to count 5 sketched objects. When I see a row of 3 and a row of 2, I get 5. When this problem intensified in later weeks, including having one of my projects dismantled by a student grading it (and then scoring it down as not having 5 holes, when I was looking at 14), I started to lose hope. When I tried contacting a mentor, coursera, or anyone affiliated with the class or the site, I found nothing except a loop through pages promising that the next one would do what I wanted if I only clicked a link.

In the meantime, I have managed to teach myself more than I need for my own purposes, have switched gears into the patent search, and have walked away without bothering with the last two weeks. If I had paid for this, I would be demanding a refund, plus damages.

In the midst, the software uploading part was somewhat problematic, hopefully, due to some technical issues, however, overall it was great!

This is the best online class that I have ever taken. Very informative, and with a lots of hands on exercises. It will require more than the 9.5 hrs announced

Great course. I enjoyed learning new skills. I learned allot about 3D computer modeling. I applied what I learned at my job and created a number of tools and assembly fixtures.

Peer reviews are terrible because there are not enough submissions.

This course was fairly good. The videos were in-depth and the assignments were pretty enjoyable. You won't learn a huge amount of 3D printing knowledge from it as the course focuses more on learning how to model in different software. It's not until Week 5 that you learn more about 3D printing, scanning, and post-scan editing. Week 5 really needs to be re-worked as it still has a video on 123D Catch which has been taken off the market for awhile now, and the two other phone apps they now recommend both cost money. Trnio is only available for iOS and isn't free on the App Store, while Scann3D makes you get a monthly subscription in order to export/download your scan to put on SketchFab (which is required for the assignment).

The peer review aspect can be challenging as well, especially towards the last couple weeks when the course is coming to an end. Many students don't continue on past the first few weeks which can make it difficult to find enough people to mark yours at the end. It might not be as bad if you're taking the course for free, but if you decided to pay to get a certificate it can add a lot of stress. A huge number of posts in the discussion boards are people asking others to review their assignments, and a majority of them are unanswered. The moderators don't respond to a large number of questions/software issue/grading issues etc. people have, which makes it difficult if you run into a problem at any time in the course. Jeff has never actually posted or responded to any discussion thread in the entire time this course has been available for people. The only posts you see by him are from the session introductions for each intake and the optional discussion post questions.

Overall, this course has its pros and cons. The videos are very well done, but there will probably be a lot of stress in other sections when you're completing it. If you're fine resolving issues that come up while taking it on your own, then it should be a good course.

Fun course with a good deal of hands on activities.

Sir Jeff progressed the whole course in neat and easy way.3D printing software carries a deep aspect involved in additive manufacturing technology.It represented several good things to practice such as Fusion360, Tinkercad, 3DScanning and delivered the art of building a learner into maker.Thank You!

Good course

A simple and intensive course to take you strongly to the heart of the best designing softwares. A great course for both professional designers as well as the beginners.

This course gives a quick overview of 3D printing SW, it prioritizes a high pace over deepness.

After the course you will gain some knowledge about 2d sketching, 3D Tinkercad and 3D Fusion 360 but don't expect to master 3D Fusion, one week per module for Fusion 360 (2 modes total) is much less that necessary.

vidoes do not provide enough information to complete peer reviewed practice.

This is the best course I have made on this year. This course give to you a chance to create objects from reality or just using your imagination. Enjoy this course, guys. Thank you for all.

Can get solid 3D software skill from this course to draw what your thoughts in mind to 3D drawing. Nice!

Very useful course I love it soooo much and I learn a lot from these course

Muy buen aprendizaje, me abrió camino al 3dscan en la actualidad y al uso de otros programas CAD

The course is great. At times it seemed like an autodesk promo, (which i found highly irritating at the time) especially when showing us features of the sketch program that are only available on paid versions, (but having student downloads of autodesk programs has also made me warm to them and feel very grateful). I really enjoyed the work with fusion 360 -a real eye-opener.

The whole thing is little bit frustrating as we clash with the real world and economic limitations. But on the whole, there are great clues in the course to progressing and the course is well worth the time.

Thank you!

Enjoyed the course and learned a lot on how to model using Fusion 360. Not sure why course 4 on 3D Printer Hardware is not being offered.

Great introduction to several 3D Printing Software like TinkerCad, Fusion 360, PhotoScan, etc. Good overview of 3D scanning methods.

Thanks to all the sponsors and Coursera for providing these course. looking forward for more such courses please add more.

Regards

The course provides an introductory course to 3DP software which is vital step to enter into the world of 3DP. It is a awesome course for 1st timer. All i want to say that an exhaustive list of links should be provided to explore more about software in case someone wants to get more depth.
