ruby in calculation string

Hi, I'm trying to have a report according to my needs.

I've an attribute named dc: um that's coming from the seed component. Is a choosing dropdown list: mq, mc, kg, etc..

particularly:

the field cost_tot should be conditioned in this way:

IF dc: um is equal to mq (according with is it choose in the dc list)

THEN cost_tot is = %a-m% * cost_unit (first operator could change for ex in %v-m% if is listed mc .. and so on)

I'm novice both SD both Ruby.

Could yopu help me?

Many thanx

Pier

The dynamic component attributes should have DC: in capital letters.

However, when I try to change it, it is converted back to lower case.

I will need to fix this and get you a new version.

Many Thanks, if it is possible give me also the exact sintax ruby in order to get my report.

Note that I've to do different calculations depending on the choices made in the list DC: um

You have dynamic component attributes on a group rather than a component.

We're you able to do this from SketchUp - or how did you place these attributes on the group?

We expect the definitions of dynamic component attributes to be stored on the Component Definition, and, of course, most groups do not have component definitions.

Can you place 'um' as a space design attribute instead, or else work with components rather than groups.

I use a dedicated plugin to build arch elements from a seed skp file that host all Dc attributes. When I draw in any model I can draw directly the element interactivly. I mean: the seed is a wall designed as group ( itm must be defined as group to work properly). Then when draw on a new model, I wil draw a vector as axe of the wall and it is build as long as the vector with all DC attributes. The final element is a group. You can find this useful plugin in skrtchucation Tak2Ata plugin. I apologize for my English.... I hope you can understand.

I can't find Tak2Ata. Perhaps that is not the exact name.

Can you find where it is mentioned on SketchUcation, and send me a link to that page?

We will probably need to find a way to access dynamic component attributes on groups to make this work for you.

Dear Pier and Al,

I'm watching your discussion about DC and the Tak2Ata plugin. I can only assume that Pier is talking about BST Building Structure Tools0.5.4 update Dec18, 2011 http://forums.sketchucation.com/viewtopic.php?t=35798.

I'm testing the plugin and I'm thinking how much info I could extract from the DC elements using SD.

Regards

Gregory

We posted a new version of SpaceDesign (see Downloads above) which will read dynamic component values from groups.

You will still have to enter the "dc: um" attribute name by hand. We read through all component definitions to find dynamic component names, but I did not want to have to read through all groups.

Give it a try and let me know if it works for you.

Dear Al,

I have the latest version of SD (LD30sd) and all the dynamic components attributes (DC: ...) cannot be input in CAPITAL letters. Only one of them can be in capital DC: the rest is automatically changed to lower case dc:. At the same time it would allow you to EDIT the lower case attribute to be capital but subsequently removes/changes the previously set to lower case.

Hi to all crew,

That's true, I'vethe same problem with imput capital letters in DC. Report seems to work the same, but I'm still waiting for some help for my ruby script problems. I've seen as Gregory work it out the report for different unit_measure, but I'm serching for more synthetic solution.

Anyway thank you Gregory

ciao

Hi Pier,

I don't know Ruby but looking at some examples online like:

x=1
if x > 2 puts "x is greater than 2"
elsif x <= 2 and x!=0 puts "x is 1"
else puts "I can't guess the number" end

and substituting the case expression (x=1) and conditions (if ... , elsif ... , else ...) to

%DC: um%=m2
if %DC: um%=m3 puts %cost_unit% * %volume%
elsif %DC: um%=m puts %cost_unit% * %DC: lenx%
else put "way of measurement is not defined" end

I wonder if the case expression (%DC: um%=m2) should be numeric (number) rather than letter + number (m2) ?
I think Ruby has some problem with the m2.

Otherwise we have to dig somewhere else.

Al,
Is my thinking correct or am I completely wrong.

Regards
Gregory
