Hello DavidJ,
So I am sorry if I was not explicit in my requirement but please find photo IMG_2626.JPG of what I wanted to create. (A simple jig to hold a tri-axial accelerometer while measuring cross axis misalignment)
So I simply ran out of play time with Alibre with respect on how to put a cube corner shape indentation in a surface and just made it up using wood filler and a cube (box) to make an impression. I guess this is similar to what you tried to explain to do in Alibre. However I find defining, positioning and moving planes and axis in Alibre really tricky and highly time consuming. Especially when you have made a learning mistake use the undo/redo function and Alibre either crashes or just locks up. It seems that Alibre just like to move forward and seems to reward well expert users, but punishes most harshly the novice and inexperienced users like myself.
A good example being a AD_PRT I did a few weeks ago. I took the original broken block and measured it up. Knocked it up in Alibre in a minute or two, produce the NC code and milled a couple out before breakfast.
Likewise the AccelOrientation-2.AD_PRT that I based this project on. A simple one minute design job, two minute NC production, thirty minutes of milling and thirty minutes of filler setting time. Compare this hour of work with the seven hours of trying to do it in Alibre and nothing to show for it other than more hair loss.
However I wonder if you are really using Alibre as my version knows nothing of STP file! Are you sure you are not using SolidWorks? :roll:
Again many thanks for trying to help me but I had to press on my way as getting the job done had some urgency.
All the best IMK
PS How do you like the improvised Sine Table made from large ball bearing and a little more Alibre.
