How can I use Pro Engineer pre-wildfire mouse controls with wildfire 2.0?
I can't stand using the Wildfire mouse controls. Does anyone know if it is possible to use a pre-wildfire mouse scheme (proe 2001) with wildfire 2.0?How can I use Pro Engineer pre-wildfire mouse controls with wildfire 2.0?
Hi Sean,
Like yourself, I also found the new Wildfire mouse controls a pain, they do take a bit of getting used to, but it's well worth sticking with it. It will become second nature in no time.
Another reason is that the pre WF mouse controls will conflict with the new selection methods used in WF
--------------------------------------鈥?br>
I'm sorry to hear that you're having a hard time with it.
I've looked in the PTC Knowlegebase, TPI-117517 explains the reasons for the changes, but there doesn't seem to be any reference to an option to revert to the Pre WF controls.
Do you work with the spin center turned off?, I find it easier this way as it allows you to rotate the model about the geometry you have selected.
I used to use a standard 3 button logitech pilot mouse and was very happy with it. I was relictant to move to a wheel mouse, but after having to use a laptop with a wheel mouse for about a week, I didn't want to go back to a non-wheel mouse.
You could look at 3D controlers.

I was given a free Space Navigator at the PTCWorld Event.
I found it pretty useless as it only had 2 additional buttons so I had to keep moving my hand to the keyboard to press CRTL %26amp; shift. Now its a paperweight. The higher end models may be better as they have more buttons to use but I've not tried one.
If you haven't already, you could try posting your question on the PTCuser froums which are quite active.

It looks like the new mouse controls are here to stay as they are being carried forward into WF3 %26amp; 4 so you may just have to get used to them.

How many hours do you think an engineer spent designing the circuitry for a remote controlled fart machine?
Do you think his job was rewarding?!!How many hours do you think an engineer spent designing the circuitry for a remote controlled fart machine?
havent u heard of the natural fart machines? they're called ';husbands';.How many hours do you think an engineer spent designing the circuitry for a remote controlled fart machine?
lol! never heard that before! thnx 4 the 10 :)
lol very rewarding I'm sure!

Who is hiring dynamics and controls engineers?
I have completed the requirements for a master's degree in mechanical engineering! My area of concentration was in dynamics and controls. I have done simulation work in tethered satellites, used computer vision to experimentally determine the dynamics of a bouncing ball, and I had an internship to develop an apparatus which could test shock absorbers in the seats of aircraft!
I would like to get a job in the dynamics and controls area but the jobs in this area seem to be pretty scarce! I have tried company websites, common job sites like monster and hotjobs, and networking and have pretty much exhausted these resources. Your input is greatly appreciated!Who is hiring dynamics and controls engineers?

My first job as a controls engineer. How do experience engineers capture I/O's for devices in a system?
I am trying to capture I/O's for devices like valves, pumps with and without vfd, motors with overload...things like that.
I also notice on previous projects from other engineers, the I/O's they had captured for pumps had 2in/out and analog 1in/out. I dont understand really why there would be 2 in/out for a pump. I know that an analog in/out would mean that they have something controlling the motor through a VFD.
So, if anyone can tell me how many I/O's for each devices I had mentioned above and describe the functional of each I/O, I would appreciate it.
Oh, and the system I'm working on is a CIP system (clean in place syst) and what the pump does it pumps water from a supply tank and is controlled by a VFD. Another pump is a return pump with out a VFD. We also have a motor in the system, that is an agitator triggered through a limit switch. So what I'm really looking for are the rule of thumb from experienced engineers when they try to capture I/O's of a system.
if youMy first job as a controls engineer. How do experience engineers capture I/O's for devices in a system?
I’m not sure what you mean by “capture I/O's for devices”
But it sounds like you are trying to write a program to control the CIP.
It sounds like the control you are working with is digital I/O and Analog.
I assume none of the equipment is smart, devicenet, Profibus, etc.
AB Plus freq drives (the Power Flex series are cheaper) require a start and stop command (2 digital outs)
Or you can jumper the 110 control power to the start terminal and it will always be in run mode, open the stop command to stop the drive.
One digital in for a limit switch to tell you if someone turned off the disconnect.
If you want the drive to send back some feed back, at speed, fault, running, etc
You will need 1 digital in for each; at min you would want a fault bit.
To control speed remotely will require an analog out (4-20 ma, 0-10V, etc)
You can send a zero speed command to stop the drive but than the drive will display a zero speed instead of stopped.
I don’t know why you would want to know the speed of the pump on a cleaning system.
I assume you would want to control pressure or flow rate because you are using a VFD drive. So you would need one digital analog in from a pressure transmitter or flow meter.
Knowing your inputted setpoint pressure or flow and the actual pressure or flow from the transmitter you would have a PID loop control the speed of the pump (VFD).
So to control the pump at this point you would need a min of 2 digital outs, 2 digital ins
One analog in and one analog out.
For the agitator, this is probably just a contactor. One digital out to start it. One digital in on the aux contacts to let you know the contactor actually pulled in. And again one digital in to tell you if someone turned off the disconnect. You would be amazed how many time things will not start because some threw the disconnect to work on it and forgot to turn it back on. If this is controled with a float to start and stop, than you will need another digital in.
Agitator one digital out, 3 digital in.
Same would go for the return pump, assuming float control so you don’t pump the tank empty.
Now if you are inquiring about capturing the data from the process, temperature, pressure, flows, ph, ect. That is another ball of wax. Omega has a ton of stuff while would require at least one analog in for each device. We use Allen-Brady PLC’s everything from micro logic to C-logic. For data capture, we use Rs-View to change settings (control varibles) and create the data logs for alarms and keystrokes. Cature data with RSSQL.
The CIP unit you mentioned looks kinda like a PLC controlled Pressure washer, I assume you want to record pressure, temp and cycle times.
I hope this is what you were inquiring, if not, I tried.
Best regards,
TheLightsAreOnButMy first job as a controls engineer. How do experience engineers capture I/O's for devices in a system?
I suggest you contact someone who supplies data collection systems. Ask them for information and price for a system to collect data from your equipment. Omega Engineering provides a wide variety of sensors including thermocouples, encoders, etc. They also have excellent technical support available over the phone. You could also contact companies that supply PLC (Programable Logic Controllers). PLCs take input from digital and a wide variety of analog signals and can transmit digital and anolog signals back out to control devices. Some of the PLC suppliers are Fanuc, Ge, Allen-Bradley.
Experienced engineers either learn it themselves (the hard way) or they learn who to call to get expert advice. If you have a Facilities group or a Maintenance Engineering function, you might find an expert near at hand.
good luck

Project Controls Engineer Vs. Project Controls Analyst.?
I work in the oil %26amp; gas and I wana progress my career further. So while searching for jobs, I found that in US/Canada the titles most advertised are Project Controls Analyst whereas, in UK I come accross a lot of Project Controls Engineer vacancies. (I know theres a lot of misuse of the word 'Engineer' in the UK). I was wondering if its just similar jobs with different titles or is the nature of work different in both? I'm a non-engineering graduate.Project Controls Engineer Vs. Project Controls Analyst.?
Not only can you not tell if the two positions are the same or similar, you can't be sure what the work entails. Project controls could refer to instrumentation or to cost, quality or schedule controls. You need to job description to fully understand the scope of the title.

ENGINEERS/PLUMBERS: THINKING HATS ON: What OTHER WAYS are there to CONTROL WATER LEVEL and WHY?
Okay, I need real, answers, if you can't think of a real answer just please star the question.
I need a way to control the level of water going into a system.
An example would be a toilet system, if you have ever noticed and opened up the lid of a toilet, to see how the flush mechanism works then it is a baloon with a lever system which controls the flow of water and therefore controls the level of water also.
So APART from the toilet can you think of
(a) any other system which controls the water level ? (e.g. toilet)
(b) the method of HOW it controls the water level ? (e.g. baloon and lever)
Btw - it has to be something which I can do PRACTICALLY and CHEAPLY.
ALL i have to do is get a PRACTICAL way of doing thisENGINEERS/PLUMBERS: THINKING HATS ON: What OTHER WAYS are there to CONTROL WATER LEVEL and WHY?
Sluices, Dams, Floodgates, Lock Gates, Stopcocks...... and they're BALLCOCKS not baloons wrongly spelt...... and how many times do you need to ask it - not once in the correct section....
I suppose it's part of your coursework so now we're doing your homework too are we....
