Cad Definition and 85 Threads

Hi, making the thread again since I posted a pic with a link, so I apologize. What particular mechanic or engineer can design/create (using a CAD, new software, etc), a hydraulic car lift to mechanically lift a car? Plus its accessories/machinery/cables in a regular auto repair shop, for the...

Hello all, Is there software that coverts a 2D part print to 3D Cad model with PMI? If you have a hand drawn mechanical drawing , 'blue print" part print with the classic human drawn tolerancing, can it be scanned to software to make a 3D CAD model with all the PM!? thank you rm

Hi Everyone, I could use some help in SolidWorks, when I go to sketch geometry, the software creates a lot of lines that extend off the starting point and they don't go away until I snap back to the starting point. I have an image attached to show what is happening. This creates a problem...

OK wanted to see how a transparent image would look like here:unsure: well first $\angle{BAC}=57^o$ by alternate interior angle are equal and then...

Hi PF! I'm using Salome, an opensource software to build .stl files. I'm trying to cut a triangular cylinder from a rectangular cylinder. Here's how I build the two cylinders: I'm building the rectangular cylinder through the hot key "build a box" toggle. To build the triangular cylinder, I...

A project, that's fun, educational, cool-looking and actually useful! What more could you want? We're making topology-optimized floating shelf brackets today...

How proficient in cad should someone who is applying for mechanical engineering internship be? I am teaching myself solidworks and i would like to have a benchmark to progress towards so when I began applying for a mechanical engineering internship in the near future i will feel prepared.

Emphasis in Computational Mechanics I possesses knowledge of mathematical bases of models such as FEM, BEM and FDM. For which I have modeled the contact of two vertebrae solving FEM by implementation using Matlab and Python. Implementation for computational acquisition of normal modes of mass...

Would you explain what a "CAD Netural Tool" mean? Ansys SpaceClaim is claimed to be one. http://www.ansys.com/Products/Platform/ANSYS-SpaceClaim Thank you.

I am working on a project and need to create several technical drawings of buildings and structures. The technical drawings will consist primarily of floorplans, schematics, and 3D models. Recommendations?

Hey! I hope this is the right place to post this. I'm looking for recommendations for a modeling/drafting cad program that is relatively affordable and capable. I have extensive experience with NX and Solidworks, but can't justify paying for either of those to simply use at home. My non-work...

Hi everyone. I know that construction lines were used when drafting was done by hand. Now, we do everything on the computer. So, how are they used on the computer? Also, how are guidelines used in autodesk? Were they not used in manual drafting also? How are they used in computer drafting...

Hi. I am trying to figure out how to get a stator and rotor manufactured for a motor I am building as a learning project. Anyone have any clue how I can get a stator manufactured from a cad drawing with electrical steel ? Everything I see on the net is for large orders sigh. I have never done...

I'd like a comparison of how various CAD programs handle the task of creating relationships among objects that have been created independently and where the uses wants to change some parameters of one object and have the program adjust the parameters of the others automatically. I'm interested...

I myself can't use CAD but just wanted to know because I think it is much more fun and artistic. (maybe I'm just the weird mechanic).

Hello, I have downloaded CAD models of a rack and pinion, and I don't seem to be able to mount them up in PTC Creo without quite obvious interference. The pinion has a pitch diameter of 24 mm, and a modulus 2. The "pitch diameter" of the rack is exactly one modulus lower than the tip of the...

I'm a high school student and I'm interested in getting Autodesk CAD and sort of playing around with it and teaching myself how to use it. I used it during a quarter long class in 8th grade, which was three years ago, and really enjoyed it. I'm also looking into engineering as a career. I know...

After searching about I've found numerous accounts of Engineers hating being stuck on CAD, and wanting something more involved. Personally, CAD has been my least favourite aspect of Engineering, so I wonder if this is the same for many others. I wouldn't fear the prospect of being say a design...

I have a cad project where i have to make an assembly of a mechanical device with 5-8 parts and I also have to make a modification to the device. I was thinking maybe a brake caliper but I am just curious what some of you think would be a good device to model?

Hi everyone, My project is nearing completion and it will be a 3d printed brake caliper with the intent on it being for education although it may see a lot of use as just a neat desktop item for people. Either way, id like to have some documentation and possibly a quiz to accompany the...

Could the orbit filling order of electrons be more classical and less quantum? I attached a jpeg and need someone to do a electrostatics analysis of the CAD model version of it. Does anyone have an electrostatics software package and have time to do a finite element analysis on a 3-D part to...

Hello everyone I am sure the answer to this would be on the internet but I can't seem to find much. When we create a complex 3d cad (examples include Aerodynamic Helmet of a cycle biker, computer mouse, exhaust fan blades etc) that includes complex surfacing in cad, how does one communicate...

I want to take a picture of an object. Then import the image into cad. And trace it. The issue I am having is the picture from the camera is a 3D perspective image. So it is impossible for me to trace in CAD. Is there a way to convert an image from perspective to orthogonal? Or create a...

Hey folks, Just wondering where the appropriate place to put CAD-related topics on this board would be. To give some context, I was thinking about posting a question about advice on constructing a Francis-vane impeller, so it feels like it falls in the mechanical engineering section; yet it...

I am a k-12 digital integration teacher/ technology director. Looking for validation to use sketchup pro 2015 as the primary CAD software for 9-12. Is sketchup sufficient to teach/train students who graduate high school and go to university programs or technical schools or do we need to use...

Hello, I urgently need to be able to draw a set of bevel gears for 3d printing. The gears I am currently drawing intersect that is their teeth are penetrating each other when the gear turns. Currently using http://www.daycounter.com/Calculators/Bevel-Gear-Calculator.phtml to find the numbers...

I am trying to make sense of these articles http://info.kubotek3d.com/3D-Engineering-Software-Tools-Kubotek-Blog/?Tag=Direct%20CAD%20vs%20Parametric%20CAD and http://en.wikipedia.org/wiki/Explicit_modeling . To me this sounds like "if using parametric relations is too complex, let's stop using...

What CAD program do people use and like? What programs use a standard data file format? It's ok if it requires me to pay. I have budget. But suggested good free programs are appreciated. What I am looking for is a CAD program to do 3D design of complicated parts. In particular, I am a nuclear...

I have an interview in next week . Can someone help me with some CAD files for practise inorder to overcome the tooltest.

Hi i want to know how to make a 3D metal box whose length, width, and height i can change. For example, i have a box of 3 m x 3 m x 3 m. i should be able to extend any dimension by a maximum of 1 meter i.e 4 meter (say). I want to use this to store items whose size is unknown, but the limits of...

Hello! I need to build an electromagnet for my DIY project. But I have a problem with choosing right configuration. But I have not found any open-source or student-license software for this goal... It would be great if someone could post some links to that kind of software.

Hi everyone, as the title says, I am looking for a 3D cad to help visualise designs in piping systems and cut down errors. As a short background, I work in a small company which occasionally designs industrial gas pipings for pneumatic systems, gas delivery systems (to a lab, workshop, etc)...

I have seen the following said on a forum: This makes good sense to me. To me, as a programmer, this sounds like he is asking for a better API to look up the coordinate at runtime; perhaps that would force the engine to evaluate expressions in a particular order, but then that's what functional...

Hi experts, What CAD program/s include a plain-text scripting language? Any free? I´m looking for something similar to Ansys´ APDL, but intended to perform boolean operations with simple geometrical shapes (spheres, boxes, cylinders, etc.) and able to generate meshed objects in STL or other 3D...

I guess this should go in this forum because I am out of school. Anyway I feel as I have a slight problem right now. I am 27 and have a BSME and a MSME but do not currently work in my field. I am lacking relevant work experience and didn't take advantage of certain things while in school. I am...

Dear Community, am 24 and currently not occupationally active. Was in Austria HTL MÖDLING: Department of Industrial Engineering. However, the last year not completed, as 19 year old teenager I could have interested me more for something else. But yet got jobs but in the field of technical sales...

Hey guys, Im in the middle of a project and need help with the base for it. I have to develop a base for a rectangle 3 feet high by 2 feet wide by 6 inches deep. The front of the rectangle is 1 pound heavier than the back and will stand 2 feet off the ground. The base must be able to make the...

I am working on an algorithm which requires the coordinates for the center point of an offset circle. Dimensions available to find this are shown in the image below and the dimension required is labeled as X: The point at the very left of the arc is a quadrant therefore, the circle center also...

I'm working on a project that requires me to use a CNC metal cutter. I'm using LibreCAD to design the thing I need to have cut (it's a radio chassis). The wiki doesn't really offer much besides a general how-to-use, and after playing around on the program I'm wondering two things. First...

hey guys For the last year, I've been learning and working in solidworks, mainly youtube videos, reading tutorials, manuals and solidworks support . But I don't know when you reach "PRO" What (else) Can I do to improve my solidworks skills.

I am making a prototype, all is ready, and the first frame of it will be made using foam and smaller moving parts using a 3d printer. Now I figured instead of cutting the foam myself I could use a CNC at a local "prototyping lab". But in order to do that I obviously have to give them all my CAD...

Hello, Does anybody know/had experience with software that can turn 2D images to 3D models in CAD program, preferably in an offline environment (not on cloud)? The resulting model has to be accurate enough for aerospace engineering purposes. from looking online, I really didn't find...

Hi, Firstly i just want to apologise if this is in the incorrect part of the forum. I'm designing and building a motorbike frame for my 3rd year project in Mechanical Engineering. I've started my research into finding the optimal geometry for the purpose of the frame, however I'm...

What are the CAD and analysis softwares most widely used by Aerospace engineers?

Hey guys, Long term lurker here in PF, first time posting though, so here goes :) I am working to help with a bid from an RFP for a Virtualized CAD Workstation environment on VMware Horizon (view). I am on the architectural side of things, not sales. One of the requirements is the ability...

Hi everyone. I've been looking at some computer aided design software, FreeCAD, and while it's to my understanding that engineers use programs like this constantly I wanted to ask if anyone knew if there programs are used in scientific computing or computational science and engineering. From...

As suggested on my last post 'how to become a design engineer' self practice is the key to learn a design program to a competent level.. At this point, I am looking for a computer so to be able to train myself, refresh my pro/E skills, and be able to apply what I read in tutorials and watch...
