For the Arial font does not work only with this value. But if doubling works well.
I changed the code:
(vla-put-width sst (distance (Car tm)(list (caadr tm)(cadar tm))))
(vla-put-width sst (* 2(distance (Car tm)(list (caadr tm)(cadar tm)))))
I intend in the future to increase. I'll put a "GetString" to capture a name for the room. Also select the name of the layer via a hatch field to define the type of flooring. etc
I am working on another project were I need to use a field, but in this case we are showing imperial and metric in the dimension. (with alternate units) the field only shows the primary units. How can I get it to show both? I've tried monkeying around with it a bit using the field expression that shows up when I create the field with no luck.
Is it possible to do this?
I'm not sure how.
but you can convert the value using the following calculation:
1 m² = (3.28083989501) ² = 10.7639104167 ft ²
can see that in my case I need to convert from cm to m² in the following line:
(setq are (rtos (* (vla-get-area ss) 0.0001) 2 2)
believe you can replicate content writing line area and do the conversion to their units (imperial)
I hope someone more expert can give a more concrete help.
...so I cheated a little to make this work.
I drew a line along the edge I was dimensioning. then I had the field reference the length of the line instead of using the measurement. This way I was able to get the units I needed, and if the user stretches the object, the line I drew will stretch along with it and the field will still update. An extra step, but it works.
