Hi John,
As I promised, here are the details:
1.
Covered by: RH-93761/Color-Linetype-for-Dimension-Components (private issue)
Covered by: RH-32049/Blocks-Scaled-with-Annotation-or-Detail-Scale
This will be possible in the Rhino WIP with this feature LinetypesWithShapes soon.
Here is a preview:
I think this is what you are doing.
The way to do this is to add a point at the end of clipping section. Group the two together. Now do the text field as text that links to the Z coordinate of the point that is grouped with the clipping section. Copy and paste the text field into the clipping section name.
Now move the group up and down and the text and clipping section name update with the Z elevation in this case. Use World X,Y, Z - whatever you want.
Here is a video of this process:
Here is a small sample model that readers can explore this with.
v8 Clipping Section Text Field.3dm (97.0 KB)
I added a feature request: RH-93763/Name-Clipping-Plane-with-Elevation.
You will need the Rhino WIP for this feature. The clipping section is now assigned to an annotation style, and the annotation style length unit control the precision.
See the video here.
Let us know if this helps.
Sincerely,
Mary Ann Fugier
