Proe isn't a really easy program to use at all!!! I tried the tutorials given with the program and forums, but they're not really helpful. This book really helps people to get a firm foundation of the program and with each lesson helps you get more and more comfortable with manipulating parts and making assemblies. However, there are some parts of this book where the author clearly hasn't checked his statements or if he had mentioned something earlier, you would be saved hours of agony and frustration.
I would sit there for hours on a lesson trying to figure out how to reproduce the same patterns in his book only to discover a much simpler way to do it in later lessons, or the fact that he left out some critical part to the lesson which you may never get unless you Read more Help other customers find the most helpful reviews Was this review helpful to you?

The author has attempted, and to my mind at least, generally succeeded, in not only presenting the mechanics of constructing the models, but also to convey the methodology of good design practice. He consistently stresses the role of planning and proper notations for the modeling process.
Stress is placed on the proper use of constraints for symmetry and dimensioning to facilitate later design modifications. I don't want to imply that the book is "preachy", it is not, there are plenty of click by click instructions. The book is terse, it must be studied. I found myself reading and Prepare to spend a lot of time following the instructions in the book and doing it more then once as the isn't always entirely clear.

It's silky solid with a little weight that makes the lead glue to the surface of the paper. The graphite-lead is held tight in place, no wiggling or slippage. This beauty's cap clicks firmly into its open and close positions you'll know what I mean when you get yours.
I love looking at it and feeling it craddle in my hand. Beautiful design, top quality material, with a refillable eraser--seasoned lead-pencil users know the value of this little addition. It's inexpensive, high quality material, precisionly crafted, great design, wonderful to hold--what do you think all this mean? It's not gonna last, Pentel is gonna realize this and jack up the price.

So far, so good; I will probably buy more. So, I've been using this pencil for just a couple of days now, and the first thing I thought was "how odd that this really nice pencil doesn't include an eraser. To reveal the very small eraser, you must snap the cap onto the back end of the pencil, as when writing. This will make the silver button at the top of the cap extend. Pull this button out from the cap to reveal the eraser.
Similarly the button of the top of the pencil body is There was another model I used and that I loved - but they're not made anymore. Close this window and log in. Join Us Close. Are you an Engineering professional? Join Eng-Tips Forums! Join Us! By joining you are opting in to receive e-mail.

The machine is meant to permit an operator to place the components onto the trays, push a button, and come back in minutes to unload everything after each tray has been sprayed and permitted time to dry between coats. I'd like to create an animation to not only demonstrate the intended final operation, but also to produce something of a motion envelope to be sure that nothing's going to get in the way of anything else.
I did finally find the Slot constraint in WF4's Mechanism section, and set that up for one of the trays. There's also a "Slot Axis" constraint selection within the Slot constraint setup.
I'm not sure what to pick for this. The automatic selection filter will only permit me to pick a vertex or datum point. For orientation, in order to keep the tray centered and upright, I used a center datum plane that is Coincident to the assembly's center datum plane, and a horizontal datum plane that is set to be Oriented to a horizontal assembly datum plane.
With all that set up, if I grab the tray with the Drag Packaged Components tool and move it manually along the path, it moves precisely as it should, following the entire path perfectly. In Mechanism though, I have some issues getting it to do a full loop, or even half of a loop. I have a Servo motor configured in Mechanism: Driven entity: Geometry. I've picked a datum point on the tray. Reference entity: I'm honestly not sure what I need to select for this.
Pro-E tells me to "select a point, vertex, datum plane, or planar surface. Motion Direction: "Select a translation vector or an axis of rotation. I chose an edge of the chain. Profile tab: Use a constant velocity. When I do a Mechanism Analysis and click Run, the tray begins to move along the selected path. But once it gets to a point where it would have to move perpendicular to the selected Motion Direction, Pro-E not too surprisingly tells me "Error - Assembly Failed! The mechanism constraints could not be satisfied.
The mechanism could not be assembled," and the tray will move no farther. I'm not sure what I can select in order to make it continue moving regardless of direction along the curve.
