To create a parametric plot, it seems that all units from an expression have to be removed. Convert, unit_free only removes the outermost unit from an expression. Are there any other commands that could be used?

The attached document describes the problem and solution attempts.

Copying and Pasting of parameters (entered data) or text in text boxes does not work on my MapleSim 2021.1 Windows10 installation.

I tired the usual keys and context menus. Cutting works.

Thats what I get back when I paste text here after cutting

<math xmlns='http://www.w3.org/1998/Math/MathML'></math>

Copy&Paste of components works.  

Is this a known issue?

I am looking for an output without denominator. I.e.:  2^(-1/3) instead of 2^(2/3)/2

Thank you

Rootfinding,Isolate seems to work on more that univariate expressions.

See https://www.mapleprimes.com/posts/215233-Another-Example-Of-A-Real-Manipulator-Model for example with a list of multivariate expressions.

Is there documentation/examples on that?

Thank you!
