Hello from Spain... and a beginner question

I have found this amazing App, just a week ago.


It is a wonderfull App, that will let me easily develop interesting interactive examples for my pupils.


I teach Geotechnics, and I was seeking for something that let me show pupils the interactions between the parameters in many geotechnical engineering designs.


The basic theories in geotechnics are just forcé equilibrium in a rigid body with limiting resistances.


I have already developed a model to design a slope, with planar failure along discontinuities.


It Works great and you can seee interactivley the effects of changing any parameter over the forces involved.


But I could not see a way to punt a text box to introduce a parameter.

Just sliders, and control points in geometry.


But the terrain specific weight, for example, is best input directly, not using a slider.


Is there a way to create an inpub box for a parameter?


Thank you for your answers, and many thanks to the developers of this amazing App.

Hi, I'm not sure to have well entendido lo que quieres :)

Sorry, I will try to explain it better.


I hace parameters such as specific weight of the soil that are not geométric.

If i put a slider I can use the slider to change the parameter.

But it is better to be able to key the value in an input box.

But I have not found a way to put an input box for a parameter in the interface, just sliders.


I am sure there is a way to do this, but i am quite new with the program

Thanks

I attach the value of a slider to an input box. See attached file. You need to set the value of the slider to min and max values you need.

hola

tal vez no hallas visto todo el GG.

en los iconos hay un triangulito chiquito a la derecha-abajo, si haces clic en el penultimo icono donde esta el icono del deslizador te sale el icono de casilla de entrada eso es lo que buscas. debes tener creado el parametro y enlazarlo a la casilla

ah! y en el foro español hay muy buenas ayudas

Thank you very much, that is exactly what I was seeking for.


I have discovered input boxes right now.


I have tried them previously, but using an object that was calculated from others, and it exposed the formula, not the value, so I thought input boxes had other uses, not just for input values.

I see that the value does not need to be related to a slider (I don't know the extreme values in advance, as you may be using different units, such as ton/m3 or kN/m3).


Now I would like to be able to key in the slope height.


I have a contol point that lets you move it and change the height of the slope.

But it would be nice to be able to key it in an input box.

But if I put the height (h) in an input box, It shows me the formula associated with h: y(HeightControlPoint).


How can I put an input box and change the y coordinate of the control point when the user keys a new value? (I suspect you need some kind of scripting).


One slop may be 10m height and another 150m height. Having to move the control point 140m in the screen is not a good way of user interaction.


It would be nice to be able to use the control point for small adjustments of height or input it directly if you want an exact value or have to input quite a different value.


Thanks in advance

Hombre un paisano. Gracias por tu ayuda.


Pues probaré a preguntaros en el foro en español, ya que veo que por aquí andáis unos cuantos.

Es que normalmente los foros en otros idiomas tienen muchas menos visitas, pero si por aquí estáis gente que controláis de esto y en español, pues mucho mejor.

Sí he visto que en el triangulito se despliegan nuevas opciones, pero no había entendido bien el uso del input box (por que lo había usado en un objeto que tenía una fórmula y aparecía la fórmula en el input box.


Bueno, no seguiré escribiendo en español por aquí, no vaya a ser que se mosqueen los moderadores (que para eso está el foro de español).


Toca seguir aprendiendo del geogebra y leer bien los tutoriales. Pero es que me ha emocionado tanto mi primer modelo y la facilidad con que lo pude construir que estaba ansioso por tener algo ya terminado y funcional.


Ya os lo subiré para que le echéis un vistazo si gustáis.

Saludos y gracias nuevamente.

With your help i have finished my first geogebra model.


It needs some polishing but it works. Here it is:

Thank you all for your help.

Very nice and well done...


I suggest you polish a little by using the Fix Object function and Absolute Position function...this way users cannot move elements around when using...I am sure the fixing you were describing were other efforts but these will keep users from accidentally moving objects on the screen.


Congratulations....

Thank you. I will follow your advices.


Right now I am a bit busy and cannot dedícate to it too much time. But as son as possible I will change the design.

Will put some things i a secondary window, and put there the triangle of forces (I will need a copy of the vector forces, as I will need to change its origin for representation, and the origin does not seem to depend in the view).

The problema would be that the names that the user sees will be different.


It would be nice to be able to have a etiquete field with objects. If you don't fill it, the object will show its name in the view, if you change its etiquete, it should show it instead of its name.

It would be perfect if this etiquete were associated with view, not just the object.


Having more tan 2 views would be great too (for complex designs).


As long as I understand, vectors in GeoGebra are free vectors. They haven't got an origin (in geometric calculations).

So the origin is just a representation ítem (to draw the vector in that place).

So the origin should be a view property, you should be able to use different origins for each view.


Any way: I will need to read more about GeoGebra, how to design interactive models with it, and its advance features.

I have read about it in its help and the geogebra manuals.

But need a more comprehensive guide. May be a book. Any recomentation?
