I have been using 2D CAD since 1992 & Mechanical Desktop for 10 years, that’s 20 years of *.dwg files. We still open and edit some of the old drawing files to create new tools & fixtures. We have Inventor 5 series but choose not to use it as it is not an efficient way of working.
Many of our customers, mostly in the Nuclear industry use AutoCAD 2D or LT. Approximately 20% use Inventor or another modelling package, usually we find ways of converting the files, but generally end up with surfaces using *.iges or basic parts with no parametric history using *.step.
My dilemma is if I upgrade my software I feel that I will be using my old software 90% of the time.
What do I do: Upgrade to Inventor Suite – or stay a dinosaur working efficiently with one system.
Are you using MDT2009 -64 bit? The performance is unlimited and would be fast even the year of 2020 in my opinion. We are exporting all our drawing to .dwg from MDT and this is our final archive. We are then adding the partlist in 2d cad.
When we arguing about non connected drawings I ask: what time is it to open this plant with 50 000 parts in 2d mode. It take 5 sec in autocad.
We have two seats of MDT6 AutoCAD 2002 32bit running in Windows XP – I have used Inventor 5 and tried Inventor 2010 on a 30 day trial: It’s very pretty to use “A bit like a crayoning package” OK it has its advantage with rendering and creating photo-like images, but I want engineering drawings.
A typical day in our office: I will be modelling a 3D press tool and 4 or 5 project engineers may request drawing modifications to files maybe 1, 2 or even 18 years old, I can quickly open any of them, modify & save them within MDT6 without changing the format. I have tried using Inventor to do this with success, but it is inefficient and creates spurious junk in the file. If I open the file back in AutoCAD I can purge the junk but a message says it has been created with incompatible software. I then have to open the file through Drawing Gateway (I could go on).
I know in the future I am forced to upgrade to Inventor, but it will create more problems than solve them.
May I suggest that we all start a pettition to return MDT back.
No more improvements or messing about. Just leave it the way it is
but offer support and conversion to other formats.
I agree whole heartedly. I know quite a few engineers who have been using MDT for a number of years, they all agree that it is the best versatile CAD package that allows the freedom to use the environment any way you like.
Inventor has some good features e.g. filleting in MDT you are stuck with what you have picked, but in Inventor you can add or remove them without deleting and having to re-pick.
I would love to see MDT brought back with some of these features added. “For the proper engineers”
I don´t understand those who working in 3d in autocad. Ok MDT is not the sexiest but compare to using autocad......
Maybe we can hope that autocad include the same functions as in MDT some time in the future.
Fore me local parts and drawing in the same file is the main reason to stay in MDT, one file one machine + that it is .dwg
I was refering to MDT 2009. I have used Acad from Versin 9 and MDT from the
beginning. The first 2 -3 versions were buggy - but now all my
mechanical drawing are MDT. Inventor may be a fine gadget for the
yong kids to play - but I am 66 and dont have the time.
Gawd, I thought I was the only one who felt that way about MDT. I used it to design plastic injection molds for years and love it. Though that work is all but gone, i still like to build "stuff". I've recently come into possesion of MDT 2006 and I feel almost like I'm back using MDT 3.0 (which was "da bomb"). Get's right on with the job, don't it? The install I have doesn't have help files so I'm having trouble with the cui files but i'll get it. Ever tried linking it to Excel? WOW, what a hot-rod. Does pretty good surfaces too if i may say so.
I lost most of 16 years of work, nearly 10K models when I foolishly asked our IT dept about an anti-virus upgrade. That's when they discovered that I had a stand alone license for my seat of AutoCAD/MDT. I design machines and stamping dies. I was still using MDT 2009 and MDT 2008 (my laptop wouldn't run MDT 2009 due to a graphics card issue) with a CAM software and had no intention of using Inventor. Who needs 2 files for each part (model and print)? Plus I couldn't get anyone to confirm that an ipw file would convert to a 2d dwg file accurately for the CAM software. Also I had banished the vaunted screen hogging RIBBON to MSHell where it belongs and was able to use tool bars and buttons. I had tried Inventor a few times and decided that I didn't need or have time to learn a 6th new CAD system. Why couldn't Autodesk have made Inventor look and act like MDT so the change would be seamless? Most people who use MDT could give a rip how the kernel works. We have a job to get done. Then the desktop hard drive puked. No worries since all of the models were saved on a server. IT says we can't have any rogues around with a stand alone license, so they sent the new box (which is a screamer workstation, thank you) and set me up with a fabulous network license for Inventor 2013. MDT 2009 is immediately dead and cannot be installed in conjunction with 2013 (no more than 4 versions back allowed). MDT files cannot be migrated to Inventor without a functioning MDT program. MDT 2008 cannot open MDT 2009 files ( I had made the mistake of migrating all of my models to 2009 format the year before) so I cannot migrate to Inventor 2008 using the laptop. Now I have to learn Inventor. I got dispensation from the IT kings to install Inventor 2012 and a temporary (3 months) license extention to install MDT 2009. Now the race is on, learn an alien CAD program and migrate all of these drawings in 3 months while trying to keep up with my regular duties which normally take up 45 hours a week. I learned enough about Inventor to start the migration in a couple of months then found out that while the geometry of the model translates okay, the dimensions for the sketches and extrusions are some garbled mess instead of a simple dimension value. AutoCAD (2d) or Mechanical can open an MDT part file and allow viewing and printing but you cannot measure anything using distance unless the layout is exploded. An assembly file is even less accessable since exploding doesn't help and the model page shows any sections and acts like a one piece dumb solid. Enough ranting, I've got to get back to work recreating all these models as needed and hope that the toolmakers don't have a question about a dimesnion on an old die.
Sorry Barry1Lau I did not get back earlier. Priorities you see.
I am having the same problems, but still continuing with MDT6 in AutoCAD 2002 now 12 years old. The drawings I am turning out are as good if not better than the majority done with later applications. They have better rendered images for a sales pitch, which is important, but I can create some pretty decent images and presentations using MDT & Office 2003. I have been creating *.dwg files since February 1993 How can I edit them in Inventor.
I wish we could do something, but Autodesk need move forward and some of us will be left behind. I will have to make a decision in the next few years, but then I may choose Solid Works or Catia as they have kept the same format.
