ah, glad to see someone esle is watching this topic as well.
Q: do you have access to Access ? (if you see what I mean !)
the reason I ask is because I've never used Vlisp to connect to a spreadsheet but I have connected through VBA to an MDB file.
Now, if it were me
I'd do it the following way:
Have all the info (Box length, width depth etc + all cylinderinfo) stored in Access and just run a query to pull the data from Access and create the whole shebang in one go. Or you could do it all via a dialogue box...
you mentioned that you have the info in a spreadsheet...
In a cell would be say from insertion point, (25"X,112"Y)
what insertion point ? is that relative to the origin of the box ? or an absolute coordinate ?
Is the nipple a cylinder a tube or a revolved solid ? Are there always the same number of fans / nipples / whatever ?
what we really need form you is some pseudo code detailing exactly the steps you need to take to complete one of these thingamajiggies
i.e.
prompt user for box dimensions
create box
prompt for face to add nipples to
add nipples
prompt for face to add fans to
add fans
etc etc
also, what version of Acad, Excel, Acces do you have ? it all makes a difference
