Now that I have the shear, moment, slope and deflections algorithms in place for point loads it is just a matter of algebraically adding multiple loads for more complex loading scenarios (ie. multiple loads and load cases). Here is a very simple example of two point loads applied to a two span beam. Note that self weight of the beam is not yet being considered:







I need to add some formatting logic into the top beam diagram to account for shorter spans so the dimensions don't run into the supports as shown. This is why a lot of testing and debugging is necessary.

This beam engineering tool with its matrix analysis engine is probably the single most complicated piece of code I've ever written, it certainly rivals the truss calculator (2013) and the complex roof (2019) module. I will admit that I now freely use ChatGPT with some of my coding puzzles lately and surprisingly it even understands the context of what I'm coding and offers suggestions to improve the accuracy and efficiency of the engine itself.

The numerical integration (for the slope and deflection) was initially stymied by incorrect boundary condition constants and I had no easy way of analytically solving for them. At that point I was fully aware of the issue but I was stumped at how to arrive at the right solution. ChatGPT suggested a normalization algorithm which proved to be correct and was even an easy fix within the algorithm. It's like having a really smart graduate student looking over your shoulder pointing out what your doing wrong and how to make it all better.

Hi all,

Just FYI for the community - we've sent Motovista multiple solutions via email & DMs since way back in July 2024, but curiously only get responses here on the forum (never via email or phone). 

If you're having email troubles, Motovista, try calling us. If you're a bot... well, you're a very dedicated one!

For everyone else: we're always happy to work with real humans on getting plans. Just reach out!

Version 4.1.3 - 08.21.2025
- Added a "Label Scaling" parameter for all wall types.





Update per customer request.

Bunch of plans there that may suit your mother....Or what about a manufactured house, not a "trailer"

Version 4.1.2 - 08.18.2025
- Added hexagon windows to the window module.



Note, that to get a regular hexagon window you will want to enter in a window height that is given by this formula:

height  = width x 0.8660254

So for example if window is 48" wide its height will be: 48" x 0.8660254 = 41.569219"

One can always enter in any size for example an elongated hexagon or squished hexagon but I suspect most manufacturers will typically only stock a "regular" hexagon shaped windows in various sizes.

Version 4.1.1 - 08.17.2025
- Added Fixed - Slider (L) and Fixed - Slider (R) windows to the window module.



These two window types added per customer request.

I would start by watching construction video's on youtube!  

You can defniitely purchase plans that you can follow, or even a cabin kit perhaps.  Lots of options, how big of a place are you thinking?  Do you have a property to build on yet?  

If there's a better sub for this question, please direct me.

It's been a dream of mine to do something like this. I'd love to build a simple small home or even an off-grid cabin. Of course, I can't just drive out to the woods and start building. I have zero experience in carpentry, framing, woodworking. I don't know how draw up plans, create a model, etc. What kind of path would you recommend I take to start learning the skills needed to make this happen someday? Apologies if this is too generic of a question. Just looking for a start point. Thanks y'all.

Version 1.5.4 - 08.11.2025
- Added "chargers" (EV) under misc. fixtures.
- Added a (Stiebel Eltron) tankless water heater and a (Tesla) wall charger/connector to the built-in libraries within misc. fixtures.
