Polyline area to table

March 16, 2021

Hello everyone.

Does anyone has a lisp that does this:

First you select (it would be great to have 'pick' and 'select' options for selecting) one or more (in that case lisp sums their areas) closed polyline/s and then you select a place in table in which lisp should enter that area.

Any help is appreciated.

March 16, 2021

Did you google there is so many pline area lisps out there.

Check LeeMacs Excellent Area lisps, of which there are a few.

Thanks Lee!

Hello, yes I did search for it and I have all the Lee's lisps, but that is not quite that.

March 17, 2021

So what is the problem or is it you want some one to do all the work for you ?

What do you have already that does not work and why. Getting total area is just adding areas into a variable.

March 17, 2021

First of all, I do all the lisps I can myself and I made over 50 of them, and the problem here is populating one place in table. That I don't know how to do and tight schedule right now.

And secondly, I didn't know there is a rule you can't ask if someone has that lisp when 90% of the people here do it and I don't have a problem with their requests and will help them if I can.

But, nevermind my question, I'll do it myself somehow, thanks for your help Bigal.

OK this is something i already have for perimeter so i convert it for area.

try and check .

thank you rlx, that is of great help....and thank you harshadp86 for your lisp, although I need to populate table cell in drawing and not Excel...

March 17, 2021

ok, so I've patched something up but it's inconsistent with filling the right cell and I also can't pick inside cell but at the edge, so can someone explain what should I use to pick inside cell

Ok I apologise just see so many times do it for me, but your having a go, if your happy can provide code for pick location for table and make a header, and title row, pick pline then use INSERTROWS function and add rows as required, this could be 1 by 1 or pick lots of plines. Happy to provide example code.

As a side answer table cells can have a field as an answer so if change pline shape will update.

no problem...

I don't need to make table cause I have premade tables. I only need to pick closed polyline/s for reading area and then pick specific cell in table to insert it there (don't want to create new table or rows)..

This lisp I made reads area and asks to select cell but you can't select it like picking in cell but selecting cell wall and depending what part of wall you pick, it puts data in different cell.

That's why I print to command line their value to track what's going on but can't find out what's it doing.

So I need like a function 'Put value in cell' that must be made in ActiveX cause you can't work with tables in lisp, and I am very bad in ActiveX (just don't understand the logic of it) so I'm guessing with my code...

That's it!

Jesus, all that programming to change cell value...guess they couldn't make it more difficult..

I could not make that on my own. Now I'll have to modify it to my lisp.

Thanks a lot Bigal

March 19, 2021

You can remove a lot of the code but you will need to pick the table still for the hittest, either do at start check is tableobj nil then pick table, note you will have to reset tableobj to nil to select another table.

here it is...don't know why to reset table when it works with more tables?
