请问如何利用浩辰机械2013制作3D螺纹？是否有视频？

您好，没有制作3D螺纹的视频，建议您可以试着用绘图——螺旋工具绘制螺纹旋转轨迹线，然后再绘制好螺纹齿形状，用绘图——建模——扫掠工具就可实现3D螺纹的制作，希望可以帮到您。

我这有个绘制螺纹的LISP程序，希望对你有所帮助
THREAD.LSP Creates 3D solid (ACIS) threads. 01/9/1999
;
; Corrected
;
; written by: Robbert Teggelove
;
;-------------------------------------------------------------------
;
; This is a way to make 3D solid external threads in
; AutoCAD R13 and R14.
; You can make threads according to:
; - ISO 228 (equal to DIN 228 and NEN 176)
; - Gas thread straight inside thread only, ISO 7-1 (equal to DIN 2999 and NEN 3258)
; - Metric inside and outside thread, NEN 81 and NEN 1870, geometrically 100% correct
;
; There is no error trapping or anything like that.
;

; The program works by creating a single thread
; and then arraying it out to the proper length. The threads are
; drawn a little longer and then sliced off to the correct length.
; This program only draws the thread, you're on your own drawing
; the rest of the screw or internal thread.
;
; Note, the threads created by this can make for some rather big files,
; so make sure your system is up to it. Also, it might take a while
; to union all of the single threads together so be patient.
