Thread Callout, Description, and Design Tables

Thread Callout, Description, and Design Tables

Thread Callout, Description, and Design Tables

(OP)
Is it possible to create a configuration table that tracks the cosmetic thread callout for each instance of the thread in that configuration?

Similarly, is it possible to have the "Description:" under "Configuration Properties" populated from the design table? (Do not confuse this description with the ones that appears under Custom or Configuration Specific.)

RE: Thread Callout, Description, and Design Tables

No you cannot populate the configuration description from the design table.

You can do it in VB however.

I was afraid it would not be a simple task. What about the Thread Callout?

RE: Thread Callout, Description, and Design Tables

I don't see a way to configure the thread callout. You can the dimensions that define the cosmetic thread.

RE: Thread Callout, Description, and Design Tables

   There is a way to model a parametric thread that can be dimensioned, that can control the configuration and dimensions of the mating thread, and that can be driven from a design table.  The technique is somewhat limited, and probably will not Cryo1's problem.

   You model the thread by rotating a sketch.

   Your sketch shows the major diameter of the thread and the minor diameter connected by a sixty degree chamfer.  These are both straight lines and one is a construction line.  Model both sides of the first thread and the profile at the opposite end using construction lines.  Apply an oblique dimension to the chamfer, equal to the thread pitch.

   You can use this sketch to control the features of the mating part.

   On a drawing of a metric thread, your dimension specification can be parametric.  Apply dimensions to the major diameter and obliquely to the chamfer.  Create a note and drag these dimesions into it and add the next needed to create a metric specification, e.g. M70x1.5.

   The thread specification does not work for English threads, but you can create a design table that displays the threads per inch.  

   This procedure does not work for thread profiles with angles other than sixty degrees, such as BSW and ACME.  It does not work with the hole wizard either.

   It works great with lens housings.
