Hi anas,

 

Grasshopper does not support dimensions (yet) as data types. So if you want to see dimensions on the screen, you'll either have to bake them directly, or handle the display yourself.

 

Which dimensions are you looking for, which properties do you want to have control over?

Hi David

Thank you for reply

Sometimes I am  asked to change  some of  the schemes of 2 dimensional  plans 3 times or more. When  I do that, I have to  set new  dimensions  step by step or delete some of  the dimensions that changed  ( become Diagonal  after they were Vertical or Horizontal)

I sometime use Record History in rhino for saving  time, but when I change some points of curves or trim curves , I have problems with dimensions (see the  two pictures  below).

Problem 2 :

After trimming , only two dimensions  should be changed depending  on their place in changed curves . But what happens is that all the dimensions become crazy!!!!!!

I always use Aligned dimension in rhino. Now I know that  dimensionsdo not exist in grasshopper. So I ask you if we have expertise in BV , C#, can we create a script for dimensions or is it impossible ??

If we can , I only need Aligned dimension.

I hope that I find or create a script that can define all points: start and end of curve ribs and create dimensions  from grasshopper to rhino directly with or without the ability to change automatically .

Thank you

I'm interested in your idea, I think it is possible to script a component that creates automatic arrow and text that lies between two points.

 

A simple trick is to draw a line between two points and place the (length of that line/dist btw the two points) as a string (text) using text tag (or 3D text tag) in the middle of the line, correctly aligned.

 

So for a poly line, you can do the same routine for all the segments.

Along the same subject - How would we rotate the text tag to match the same angle as the measured curves?

Create a Plane using the Curve as a guide. Probably in the form of a PerpFrame and then get the plane components to re-orientate it. Then use the generated plane as the location.

I was able to get this far - but the problems are obvious - any thoughts?
