Re: Problems With Cad on your team?
For 179 cad is always used, but very hard to work into part of the mentor education process during build. Some of the problems we have are computer access at the school, and being able to transfer files back and forth from school and home/work through the school firewall. Since the design process usually takes a few days of non stop work, you can't be at the school all the time, and you can't transfer the files in and out through the school firewall. We need a way to host files that we could get at from anywhere, including through the school firewall. But I'm not sure how we can do that as the administrators are kind of like OZ out there somewhere. CD burning is a pain and can be risky as data might get corrupted or lost/overwritten and finding a burner is a crap shoot at school. I'm glad I saw this thread cuz now I'm going to ask the students to pull this off. Unfortunately the firewall has hindered us in many ways, keeping us from models on line and we can't use Chiefdelphi there either - as it's a chat forum. I know they mean well, but in our circumstances, they stop our progress too much.
This year we're trying to get the students to use CAD prior to kickoff so they get more exposure to it. But in the previous years, our meeting nights are short and the design process is usually happening at peoples homes shortly after kickoff. Last year I spent 24hours straight modeling our design so we could get the parts made at the water jet the next day. That was fun! I'm leaning towards teaching them AutoCAD since it's still more of an industry standard. Though Inventor has more capability I just think it's probably more useful to give them experience with something they're more likely to use in a typical workplace - since AutoCAD is so much more adaptable. I know Autodesk doesn't want to hear that, but in my experience it's true. |

Re: Problems With Cad on your team?
Using CAD can eat up a lot time. Typically, we use drawings (and some CAD) to get a (fairly) accurate schematic of our robot. After that, the Inventor and Mechanical teams work concurrently on the robot. The Inventor team spends their time modeling the robot in 3D and making sure there are no problems with measurements, etc. The mechanical team uses the drawings and whatever is done in Inventor up to that point to build the robot. We're usually able to crank out both a good inventor submission and good robot in 6 weeks by using this method.
If you're going to use CAD, make sure you learn it before the season starts! Best of luck! |

Re: Problems With Cad on your team?
Thats a good idea spaceosc, and cory has my point. If I make a change to a file that Tytus needs, he and I will need to remember to copy the files both ways every time. It's just best that the file be accessable from one location. But that still is a good alternative I forgot about. I've wanted one of those things anyway.

Re: Problems With Cad on your team?
Just to comment on the multiple versions of files topic...
I know this is probably impossible considering your firewall situation, but our team purchased a cheap $500 Dell server that serves a central repository for all of inventor and CAD files. We used Active Directory to setup accounts for everyone. We setup a small LAN consisting of the server and whoever has a laptop. With AD you can login to the network and access all of your files no matter which computer you may be using. We also used the server to net render our 3D animation across many laptops. With servers being so cheap, it may be worth it for your team to invest in one. The key to efficiency is good organization. Good luck! |

Re: Problems With Cad on your team?
Maybe this goes without saying, but the problems I have experienced regarding CAD and FIRST teams has little to do with the CAD software itself. Rather, students using the software, while they may be proficient in the software interface itself, still often lack design sensibility. Knowledge of common manufacturing practices and standards is just as important as the ability to develop an assembly in Inventor, if not more.
If you have the time to devote to the task, I don't see time as being too worrisome a constraint. I have, in the past, designed entire robots in CAD by myself and done so within a week's time. More people working in tandem with a good understanding of project management, the software, and standards of design and manufacture should be able to do this with little difficulty. |
