CAD Program (Autocad Lite)

[Erel]

You can change your textbox to a multiline textbox. This way it will not beep. However it will require to always make sure that the cursor is in the first line and that the CRLF is removed.

Thanks Erel. The only problem is that I have over 2000 input text boxes in my survey program. It will take some time to change them all!

Anyway, I am attaching an updated manual (chapter 5) on the CAD section.

Thanks

2000 textboxes???what for?
i'm think manual it's not need now.

Hi Byak

What I have done, is to take a Civil Engineering and Surveying Program that runs on a PC and ported it to a PPC. The whole program consists of over 43000 lines of instructions and it's still growing.

Lets take a simple thing like entering the geometric parameters that make up a road:

1. You need a horizontal alignment, consisting of Pi coords (X & Y), a circular curve and two transition curves. Next you must allow the user to enter different types of spirals. (That's 6 input boxes)
2. Next you need to define the vertical alignment. Again the stake and elevation of the intersecting point, the length of the vertical curve, symmetrical or assymetrical curve, the type of curve (parabolic, cubic parabolic, circular, etc).....another 6 input boxes.
3. Then the surface.....surface widths, widenings, crossfalls, superelevations, kerbs, sidewalks, shoulders, etc. .......12 input boxes.

Still staying with the data input module, one also need to give the user the option to import design parameters from other programs, ie. CEASER_office, Model Maker, Civil Designer, MOSS,etc. Then there is of course the option to export your design again to other programs.

And so I can carry on and on. I am sure that if one goes through the program again one could get rid of some input boxes, but that is the way I programmed it.

I hope that it sheds some light on your question.

I do not understand your last sentence?

Thanks
Michael

i'm found a interesting thing
Pocket PC CAD (DWG/DXF/PLT) Viewer - CAD Import .NET - áèáëèîòåêà äëÿ ÷òíåíèÿ AutoCAD D...
it is a example for pocket pc for vieving Autocad files!

Hi

There is an updated version of my feable attempt to have a CAD module in my surveying program.

Some things that I have changed\added:
1. The actions of the bottom icons were moved to a menu and the icons removed. The idea is to have the functions that one uses the least to have them on the menus and the other functions as icons.
2. Distances and areas. I am not too sure whether they were there on the previous version.
3. I have introduced the concept of "Construction Lines". These are lines that one draws to help you in your drawing. They are placed on a special layer and you also have the option of saving them in your drawing file or not. If you do not save them (click the option under "Setup") and you load your drawing again, they will be gone.
4. The DXF import has also been improved.
5. Functions like "Station Setup", "Orientation" has been removed, as these functions reside in the "Field" module.

I would really like to have comments from the Forum on improvements and ideas.

Thanks
Michael

P.S. there are still functions that do not work (i.e. dimensions), but they should be fixed up in the next update!

Hi Michael, I also have migrated from using Psion and OPL (per Psion programming). On Series 3 (I never upgraded) I had a freebie CAD program which came with a demo image; see http://www.basic4ppc.com/forum/quest...html#post33583.

So I tried exporting that demo to DXF and importing it to your CAD module (running under the desktop IDE) but it looks rather garbled and upside-down! When imported to OpenOffice Draw module it looks nearly the same as on the Psion.

Best regards, Mike.

Hi MJCoon

Thanks for the comment. I have totally rewritten my "CAD" program as a standalone from my Land Surveying program. There were a couple (actually quite a lot) of bugs in the program which have been fixed.

Give me about a week then I will post the new version on the forum. I just want to test it with the new version (6.90) of Basic4ppc.

Regards
Michael

Hi Michael, how's it going? Cheers, Mike.

Hi Mjcoon

Give me another week or so.

I have started another project in Mozambique and it is very fustrating! These people have no sense of time. I have come to the conclusion that their calender does not have days in it but only weeks
