Search the Autodesk Wiki help for: "Create expressions for iProperties"
Doing it this way allows the properties to "Look-Up" the value within the "Parameters". Anytime someone changes the Parameters value, it will be updated in the properties, which is what the BOM looks at.
You may want to create a IPT template with these changes done. Then when everyone (or you) uses the template to start a new part the fields are in the properties
Thanks for the reply.
I will review those things.
Please take a look at the attachment. Currently, I just made another sketch in the *.ipt file and put a reference dimension around the corners of the part (this is only a rectangular plate with a taper on one end). This allows me to get the reference dimension which is automatically updated whenever I change the taper angle where I use DRAFT command. But it would be much better if I can get the dimension manually made inside *.idw and take the value of it.
You may want to change up your work to have the <Length> for your top dimension, <Height> for the LH height dimension and then deciding which dimension you want to use either the <Angle) for your RH end or <Taper Length> for the horizontal component.
Then set these as the required in the wikihelp document for your fields.
As long as the rest of the sketch is properly constrained you will have a solid part that can be changed and BOM will update.
You could do that. Probably about as many ways to do this as there would be people who looked at it.
