The Logopress3 help file recommends that when using “Unbending by steps”, you should pick the inside radius. But in reality, it really doesn’t matter which you pick. I almost always pick the outside radius myself, because it is always obviously a bigger target and is always closer to you. But when an unbending doesn’t work, whether you pick the inside radius first or the outside radius, the first thing you should try is to pick the opposite one. Very often times this works.
I’ve had this chart shown below for well over a dozen years. I’ve found it to be very useful for quickly adding a symbol to the document you are working on; particularly when working with emails describing things such as diameters and plus/minus dimension and angles. The trick is to simpy hold down the Alt key on your keyboard and while you are holding it down, you simply type the 4 numbers corresponding to the symbol you want and then release the Alt key. So you can quickly type 0.251Ø or 30°±1°
3D CAD software certainly requires more overhead than 2D CAD software that simply draws lines and circles. After purchasing the right software and proper training, the next part of the equation is certainly the most overlooked in my opinion. The disappointing part of it being overlooked is that it can have a huge negative impact on efficiency and it is definitely the least expensive part. We spend a great deal of time keeping current with new hardware and interviewing our customers to measure their experience with their hardware. Computer hardware is constantly changing and we would be happy to discuss with you what we have found to be the best current solution for running SolidWorks, particularly for die design.
