dimensions & formulas

dimensions & formulas

(OP)
Does anyone know how to add variables to dimensions that dynamically update with the association? (ie. if a dimension needs to show a value of actual length + 1/10 of actual length, how would I enter the formula <>+(<>/10) and get it to work?)

RE: dimensions & formulas

i have a feeling there was something on this under DIESEL in Acad Help.

RE: dimensions & formulas

No,
That's not it. I want to insert an actual mathematical equation that would drive the text output.

No math formula is needed.
You can do this with a 'brute-force' solution.  By adding in 'alternate units', and scaling appropriately, you can do what you've asked.
If you need a +/- or such, you can put that on the prefix for the alternate dimensional units

Dear Andylaug,

This is possible just by programming,
AutoCAD VBA: Events
Visual LISP: Reactors

RE: dimensions & formulas

If you are working with mdt.  Set the sketch dims setting to parameters.  Your sketch dim will look like "d1", "d2".  now edit the desired dim to "d1=d2+d3".  As the dims are changed the formulated dims wil update.  In drawing space, the numbers will appear real.  You caught me away from my work station so I'm doing this from memory.  Under the dims settings you can add "pretext and subtext" so that all dims have can read   pre "<>" sub.
