As alternative one can develop a region that translates into a TextBox control with mask/validation filters. It might be tricky depending on the filter but it is feasible.

Pretty simple to zap negative values: 1. transform negatives to '0' 2. strip vector from '0' No need using Smath Viewer. Cheers ... Jean. Random [rnd(n)] Filter.sm (11kb) downloaded 9 time(s). Composite clean negatives. Thanks Jean, but it's not the case. I have an long application developed in Smath Studio using Smath Viewer, and some of my algorithms need's a positive input for bending moment's. For now showing a warning message, and using an absolute value work, it's not the more elegant solution, but work.

The very original document at the algorithms level might help. Not my discipline, but curious. Refreshed version of the previous Filter Negatives. Jean. Random [rnd(n)] Filter.sm (11kb) downloaded 9 time(s). Sure! The document is here: DIMIS_219.sm (839kb) downloaded 15 time(s). The section is called "Flexão Composta" the value of Msd, for this algorithm need's to be positive.
