Supports/support fixity could be confusing for users. There should be a specific fixity object that handles this, istead of the a list of fixities in each DOF.:

Often we will want to know the values at a specific point on a SFD/BMD. It would be great to add an ability to inspect results at the input location. and return the closest value.

Hello,
Firstly I really like your library. The simplicity of doing simple hand calculations is perfect. I am relatively new to python so I apologise if the queries are simple.

1. Is it possible to output key (peak) values from the bending moment/shear force diagrams as numerical values? I have read through the documentation but could not see an option of extracting, for example, the peak. It may also be good to have these as a label on the plot outputs.
2. I noticed in the documentation there is a parameter 'scale' I presumed this was to change the size of the plot but on testing different values I can't seem to change the size of the output plot. Can you clarify what the scale parameter is used for and how one would change the size of the plot output?

import planesections as ps

Define node locations, and support conditions

L = 5
beam = ps.newEulerBeam(L)

Define beam and fixities

pinned = [1,1,0]
beam.setFixity(L0.1, pinned, label = '1')
beam.setFixity(L0.9, pinned)

Define loads

Pz = -1
beam.addVerticalLoad(0, Pz, label = 'A')
beam.addVerticalLoad(L0.5, 2Pz, label = 'B')
beam.addVerticalLoad(L, Pz, label = 'C')
beam.addDistLoadVertical(0, L, Pz)
beam.addDistLoadVertical(1, L0.3, 5Pz)

Plot the beam diagram

ps.plotBeamDiagram(beam)

Run the analysis

analysis = ps.PyNiteAnalyzer2D(beam)
analysis.runAnalysis()

Plot the SFD and BMD

ps.plotShear(beam)
ps.plotMoment(beam)

Add a labeling system for point of interest on the graph:

Could you please update the graph labels to show:
Shear Force VS Distance
Bending Moment VS Distance

Also, it appears that the units are fixed to Newton and meters, could you please create an input for the units so that it can show SI units and US customary.

I want to plot my simple truss (2D) and space truss (3D). Can I use this library only for this use case? I don't need the analysis function etc.

In this line, is it possible to install planesections with pip without the dependencies openseespy
