    2d Curve Tangent
AI Thread Summary
To create a tangent line to a 2D spline curve in Pro/Engineer Wildfire 2, users should utilize the tangency constraint found in the constraints box of the sketcher menu. However, some users report issues with the spline not being detected by the tangent constraint, complicating the process of creating a circle tangent to the spline. Additionally, difficulties in placing a point on the spline curve have been noted, indicating potential limitations in the software's functionality. Alternative methods for achieving tangency may need to be explored if the standard approach fails. Effective solutions for these challenges remain a topic of discussion among users.

How can I create a line tangent to a spline curve interpolated with several points in 2D in pro/engineer wildfire2.
 
Engineering news on Phys.org
place a tangent constraint, it must be there in the some menu
 
There is a constraints box in the sketcher menu. In that box is a tangency constraint.
The icon for the constraints is the 6th from the bottom.

I already tried that.

In pro/e with tangent constraint, the spline is not getting detected. My requirement is to create a circle tangent to a spline.
Even I am not able to create a point located over the spline curve.
Is there any other way to do it.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
