Hello, sorry to bother you, but you seem like one of the few around tumblr that has fun with CAD. Do you have any suggestions for us who'd love to learn CAD but pretty much has no schooling around us that teach these things? Thank you, love your blog!

I didn't have proper schooling I just learned through trial and error and tutorial videos (youtube is your best friend) and lots of googling/looking at forums. I also have the implicit requirement that I want to own my own tools so I don't tend to use the two largest 3d modeling softwares. The two main ones are Fusion360 (the most popular, but I don't know a good tutorial series for this) and OnShape. OnShape is browser based, Fusion360 is a windows application (get used to that if you want to do CAD work). I personally do 3d printing, and there are loads of youtubers who go into designing for 3d printing. I personally trust TeachingTech. This one uses OnShape.

I currently do my Modeling in FreeCAD, specifically the realthunder/link branch. which i believe is getting merged back into the proper "FreeCAD" soon(tm). I used this tutorial series by keep making.

I personally think he is a bit of a tool. but he showed me enough that I could learn either by trial and error or googling things I wanted to do. Just to avoid headaches, if you want to try FreeCAD i would recommend Ondsel instead, because its built from FreeCAD and includes a lot of things not currently in the stable release of FreeCAD (including the Link Branch I use). I'm simply familiar with the current UI and can't be assed to change.

Want to build your own Piano Coat Rack?

I put together some plans for the Piano Coat Rack so that if anyone else wants to try to make one they have a starting point. I ended up putting them on itch.io for free since tumblr doesn't really like PDFs or zip files. The plans are free for non-commercial use. I also have a section describing some of the process to hopefully make it fairly easy to replicate.

I put these plans together in FreeCad, so along with a PDF version of the technical drawings there are also full 3D models that you can use to get a better understanding of how it goes together. If you notice any oddities or mistakes or have any question please just me up!

Also if you make one please tag me, I would love to see it!

Cad Bane is so difficult to draw with his alien noggin'. I often have to refresh my knowledge of his bizarre dimensions. These are observational copies from various screenshots from the shows (The Clone Wars and Bad Batch). Maybe these sketches will help other artists understand his ridiculous (but gorgeous) bone structure. His forehead is very round. Just draw a large ball, tbh. It has 3 wrinkle lines that make an M shape. Those brow bones in particular, wtf. They're also equi-distant as the nasal bridge. Why yes, I do draw pupils at first. Then I promptly erase them. Pupils change the shape of the eye lids because they protrude just a bit further out than the rest of the eye. Although some Doros have slit pupils, Cad Bane doesn't in either cartoon or live action versions. ------------------------------------------------------- xInAmberCladx's Fanart Archive <-link

How do you feel about Mandy's cannon 3D model? (The officially licensed video game spinoff)

[brightgreendandelions]

i want to 3d print a box, with this kind of sliding lid, and i'm not sure how to pick my tolerance. the lid is 3mm thick, and will be printed separately.

in hindsight, `lid_margin_bottom` should probably be 0.

I think I'm going to make Jinx's Zapper from Arcane. It sounds like a fun print and item to have on a shelf. Idk what I'll do with it, but I wanna design it to be easily painted, maybe I'll sell it or something when I finish...

This is just an fyi for anyone trying to write about construction industry people.

One cannot draw/draft a blueprint. Blueprints are like photocopies of plans to be handed out to other people.

Architects, engineers,and other professionals that need to present drafts make plans (floor plans, roof plans, ceiling plans, electrical plans, road plans, elevations, etc.) in black ink. When everyone agrees on the final draft, they make blueprints of these plans to distribute to those that need them.

One more thing.

Technical drafting/drawing isn't like free-hand or painting. Trying to draft outside is hard, since lines have to be level, and it's hard to mount paper anywhere that isn't a flat, solid table with 90 degree corners (for the T-square), and some outdoor furniture are not like this. You also don't want the ink to run or the paper to get wet, so no drafting on the floors. Best choice is a portable drafting table/surface if the character really needs to do this outside.

CAD to BIM in AEC Projects

In the modern architecture world, CAD to BIM conversion is now widely adopted technology which made the construction process much easier, faster and more accurate. It is an effective solution for the complex process of construction as CAD to BIM helps to visualize the entire project with better clarity, understanding and communication.

These photos are from the air flow simulation I did yesterday, to find out what impact the wind would have on the structure of the identification buoy. I recorded the animations to make it easier to analyze.

It was fun to do this, I discovered that I can make several different types of fluids, which could be useful in future projects. The article is almost ready, along with the boat and buoy codes.

Here are the charts with results generated from Solidworks:

Generally I don't do this, but I'll put the translation of the analysis I put in the article here, maybe it can help someone.

Although it is not common to carry out engineering tests in this specific context, we chose to conduct an analysis dedicated to aerodynamic conditions, aiming to understand the effect of wind on the structural integrity of the buoy. To carry out this study, we used Solidworks, making use of the fluid simulation system incorporated into the program.

Initially, we modeled the buoy structure, assigning specific materials to each component. Subsequently, we establish the necessary boundary conditions to faithfully simulate the behavior of the structure in real conditions. In the next step, we created surfaces that represent the wind pressure in the region where it impacts the buoy, and defined the area in which the wind pressure would be applied. The application of wind loads and adjustment of analysis settings were carried out using the “Flow Simulation” tool.

This process allowed an accurate representation of the aerodynamic conditions on the buoy structure. Additionally, we adjust relevant parameters for the analysis, ensuring a comprehensive approach.

The simulation execution culminated in the generation of a comprehensive report, documenting the results obtained. The interpretation of these results provided valuable insights into the structure's performance under simulated aerodynamic conditions. This engineering test highlighted the importance of considering aerodynamic conditions when assessing structural integrity.

It is possible to highlight some fundamental reasons for the importance of this analysis, such as the assessment of structural integrity, assessment of operational safety, design optimization, which can result in savings in materials and manufacturing costs.

The Montagem_boia.SLDSAM model was configured with standard parameters, carrying out 57 iterations to achieve convergent results. The mesh was defined with basic dimensions (Nx = 40, Ny = 9, Nz = 17), and boundary conditions were established to represent the fluid environment of interest.

The physical time interval considered was 0 seconds, and the CPU time required for the simulation was also recorded. The simulation results revealed an interesting distribution of fluid properties and flow characteristics. The total number of cells in the mesh was 7626, all occupied by the fluid. Among these, 1106 cells were in direct contact with solids.

The mesh dimensions (X,Y,Z) indicated a significant extension of the model, with minimum and maximum variations in each direction. Analysis of the velocity field revealed a range of [0 m/s; 7,510 m/s], indicating different flow regimes within the simulation domain. The pressure varied between [101294.37 Pa; 101430.23 Pa], with a reference pressure of 101325.00 Pa. The temperature remained relatively constant, with values ​​varying from [293.20 K; 293.21 K]. The fluid density showed a minimum variation, within the range of [1.20 kg/m^3; 1.21 kg/m^3].

There was no consideration of factors such as heat in solids, radiation, porous media and gravity to simplify the model to meet the specific objectives of this simulation. Based on the analysis of the images obtained, the reduction in wind speed becomes visible when facing the structure of the identifying buoy.

Notably, the average wind speed in São Paulo, situated at 25km/h, is insufficient to cause damage to the aforementioned structure or to displace it from its original position. It is also worth noting that, when encountering the obstacle represented by the buoy, the wind flow tends to bypass the structure mostly from above, to the detriment of the sides.

This observation suggests an effective resistance of the buoy to direct wind impact, contributing to its stability and structural robustness. The results clearly indicate that the structure's resistance to wind action is remarkable, since the force exerted by the wind did not reach levels that would compromise the integrity or stability of the configuration.

The solidity of the structure in the face of these conditions suggests that the design presents a robust and adequate response to the expected wind loads.

Sorry for any grammatical errors ~

I have a lot of experience with tinker cad, so... 3D Mandy! (I know she is still technically flat, but still. might make a fully 3D model version though? depends on interaction amount.)
