Geomatry Resizer or Paramatric???

OscarLok

application: for architects, this would mean that if they need a 200 square foot room, and they could change one length of the room to fit a certain space, and then the other length would change automatically, while maintaining the proper square footage (or square meters) area size of the room.

Hi Fletch,
It may be possible!
May I know that is the room always in rectangle shape?? or more than two length (e.g. L-shape & etc) which has more than one unknow element(but still possible).
Could you please send me some room shape which you do normally.

Regards
Oscar

It's really really promising script
but let me ask you somthing...

1_Is it possible to lock some edges to make constraints to geometry?

2_Can you edit parametrically only the lenght of a segment or also the angle between 2 edges, the surface or somthing else?

3_ Does it work only on edges or also on arcs and curves?

Thanks for putting your time in developing good scripts like that

a4chitect

very nice oscarlok! you are building something very useful! gjenio pretty much summarized all my questions or feature requests, I second the wish for

edge position/length locking

face position/area locking

any angle locking

this could help model more accurate approximations! good luck

Edson

very promising. let us know when you finish it.

Hi Oscar,
initially, just rectangle is fine, and I agree with the idea of the others that you could 'lock' the position of an edge so that it won't move.

the ability to do an L shaped room would also be good... that is, if the room were an L you could select faces to 'lock' and the rest would be able to move (assumed that floor and ceiling would automatically be 'locked'.

of course, the next step would be the ability to link this to an excel file and have it build the spaces automatically from that file.

Hi a4chitect & Gjenio

Let me see... I have to think that which way to execute it.
I will show some avi after it has been done.
VERTEX, EDGE, FACE, ANGLE....(one by one) Give some time.
What I have done are:-

Select an edge, AUTO indicate the two side as point A & B
Enter the NEW length
Select which side(ponit A, B or bothsides) of the edge to ADJUST (similar to LOCK 1 FACE)
What I am doing now is :-
Select a face to lock, then repeat the above.
But, the script will adjust the edge ONLY in step 3(similar to LOCK 1 Vertex??? or Edge???).

Actually, I am confusing what I am doing now, is it Resizer or Paramatric?
I maybe wrong, I think that what you descript is more to paramatric geomatry. If I am not wrong, parametric needs formular to make constraints to geometry.( similar to my old script "OSCarcase" )
I will rewrite the OSCarcase to make it easier !

I thought there are some ruby scripts regarding this idea already !
May I know what is the data or format in the excel file,please ?

I need more idea about paramatric geomatry, please!

Thanks

Rick Haws is working on a similar project, take a look here

Hi Oskar,

Could this be of any help to you.

Hi Gjenio & Bep

Wow! The sketchflat program is great. It is a two-dimensional technical drawing program. Lots of information !

3D Autonomic Dimensioning is great tool.
Hi Rick Haws, I would like to know how this is progressing ?

Thanks
Oscar

OscarLok

After reading the tutorial of sketchflat program, I use my two script ( OSCresizer & OSCangle) to try to do the similar drawing to the tutorial.

I found that it is very interesting to write a parametric geomatry script. I may try to start from 2D, then 3D.

Here is the rough demo :-
http://www.youtube.com/watch?v=c-OYXKwg2WY

In the AVI, I draw trapezoid (The word trapezoid has multiple definitions. Here is to describe a four-sided polygon, with two edges parallel and the other two equal in length.) and then change it into triangle .
In the demo, it show the "Both Side A & B" Adjust, that means no lock to both side (as I describe previus reply). It show the one side locked or the other side adjusted, too. We can choose which side to lock or adjust.

Hi Oscar,

At last!
I am very glad that you are taking a real effort in making a Plug-in or ruby that could
Make Surveying with trilateration possible.
My big-wish for a tool like that is very old.
See http://groups.google.com/group/Ruby-API/browse_thread/thread/9a853979f28f4c46/dab01f684101c6e4?lnk=gst&q=bep+van+Malde#dab01f684101c6e4
From these links please try out the Mobile cad Demo to get inspired.
See also my request from last week. http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=9718
The Sketchright program is not available anymore but is as a good example ,so I will try to PM you , to find a way for you to explore the program.
(I am glowing from anticipation .)
Oscar you are one of the Ruby hero’s.

Hi Bep,

The MobileCAD is only in German. Do you have any video tutorial regarding its' U.I. and the process of drawing a floor plan, please? (I would like to try to understand it by visually.)

Let me see weather there are orther way to make trilateration possible.
What I understand is to lock two edges' length and adjust the third edge's length. I may be wrong.

Oscar

Bep

Hallo Oscar,

I to have only the German Demo version.
One of the great advantages of the Mobilecad program for trilateration is that it triangulates the sketch of the floor-plan for you, and you can toggle trough the different triangulation options until you find the one that is right to you.
Although I think you should also be able to triangulate it yourself.
Than you just fill in the real size of every (blue) line, the colour chances afterwards to indicate that it has been scaled to the right size and it automatically locks this line-length.
The program scales the floor plan after every input, so you are visually warned if you fill in a really wrong dimension.
One of the key words in this process is over- and under-constraint warning.
Ill try to explain that as far is I think to now : for example a four sided figure from which only the four sides are known can not be drawn and is called under-constraint ,whereby as one diagonal is also known it can correctly be constructed, but when you try to incorporate the second diagonal in the drawing the figure is called over-constrained meaning that mathematically there will always some sort of rounding (or there has been made a small measuring error ) difference, the math solver will normally not allow that, and so a over-constraint warning will pop up.
Please look at the video

By the way I am doing a posting about a little bit similar issue at http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=9718

Thanks ! Bep !

You give me a lot of imformation ! Let me see what I can do.
I have start it.

Oscar
any suggestion are welcome !

Bep

Hello Oscar,

I forgot to mention that if possible,you should be able to exclude a part of a face from triangulation (this is not possible in mobilecad ,and thats the reason I cant use it)

Greetings, Bep

part excluded from triangulation.skp

OscarLok

Hi Bep, a4chitect & Gjenio

There is a new 2D parametric geometry avi which lock the edges in the first POST . It show that how to make the trilateration. We start to do it by select a face, then we can lock the edge we want.
By the way, we can adjust (or lock) which side(or both sides) to be adjusted.

This is just a quick test. Don't know is it the correct way.
If it is the right way, I will develope it further !

Oscar
