 Tune in to discover how Additive Restoration uses 3D scanning, digital modelling and additive manufacturing to recreate rare parts and keep classic cars on the road. OverviewIn episode 67 of The Third Angle, PTC's podcast hosted by Paul Haimes, Steven Dibdin, founder of Additive Restoration, explains how 3D scanning, CAD and 3D printing are used to recreate obsolete parts for rare Ferraris, Alfa Romeos, Maseratis and other classic cars. PTC's Michele del Mondo then explains what restoration teaches the wider automotive industry. The episode runs 19:49 and was recorded at Dominick's European Car Repair, north of New York City Key TakeawaysA rotor arm made from composite resin got a 1955 OSCA engine firing properly again. The engine had been running on only half its sparks for around 20 years, and the new part reportedly added 10 to 15% power 1. The aim is to keep cars as they were designed. Known weak points are fixed only when the change can't be seen 1. A 3D scan of a valuable car wo

Scenario / QuestionHow do I use a plus/minus (±) operator in Mathcad Prime, and does Mathcad Prime include a built-in ± operator? OverviewMathcad Prime does not include a built-in ± plus/minus operator that can be used as an infix operator in expressions. A workaround is to define your own function that returns the positive and negative variations of a value, but it must be used as a function with parentheses rather than as a true ± operator. Step-by-StepDetermine whether you need a display symbol or an operator: A ± character can be displayed using supported Windows fonts, but this does not provide mathematical operator functionality. Create a custom function: Define a function that represents the plus/minus behavior you need. Use the function in prefix form: Call the function using standard Mathcad Prime function syntax with parentheses around the argument. Evaluate the result: The function can provide equivalent plus/minus behavior, but it cannot be used as an infix ± operator withi

Scenario / QuestionI stumbled randomly on the following in PTC Mathcad Prime: it seems that Mathcad defines atan and tan⁻¹ differently. I thought that atan was the same as the inverse tangent, but that does not appear to be the case. Shouldn't atan and the inverse tangent be the same definition?OverviewThey are deliberately different. In PTC Mathcad Prime, atan(x) is arctan, the (limited) inverse function of tan, while tan(x)⁻¹ is the reciprocal 1/tan(x). This is correct and intended behavior: where a trigonometric function has a named inverse, the superscript ⁻¹ is read as an exponent. To get an angle back from a tangent value in Prime, always use atan.Step-by-StepOption 1: Get the inverse tangent (the angle)Use the atan function: Enter atan(x) where x is the tangent value. Prime returns the angle in radians, taken from the principal branch. Convert to degrees if required: Append the desired angle unit to the result, or format the result with the unit, so the value displays in degrees

If you now go to Mathcad's website, you'll be redirected to the Mathcad page on PTC.com. You'll also notice there are suddenly a bunch of new Mathcad pages on PTC.com that weren't there before. And you'll notice that Mathcad is a "Featured Product" and Engineering Calculations is a "Technology" on the PTC top navigation!   Yes, this is all intentional. If it seems like I've been quiet for the past several months, that's because it took a lot of work to return Mathcad back where it belongs! (And if you were wondering why new Mathcad blogs and webinars were being published to PTC.com and not mathcad.com for the past half a year, or why old Mathcad webinars are being uploaded to the YouTube channel, this is why.)   PTC.com, in terms of available technology, security, and usability, is vastly superior to what mathcad.com can offer. I hope you all see a lot of benefits to this move.   If you have any questions or found any glitches, please let me know!
