Rules for Dimension Notation on 3D Viewer

The rules for displaying dimensions relating to outer diameter, inner diameter, surface roughness and holes are as follows.
Outer-Most Diameter (Non-Precision)
Settings Non-precision
Thread Length Settings
Specified length on left side Specified length on right side Specified length on both sides Fully threaded
Image
Set Value ø30
M30 thread length min.7mm​ M30 thread length min.7mm​ M30 thread length min.7mm​/M30 thread length min.7mm​ M30 thread length min.15mm

Tip

When setting the thread in meviy, fine thread is displayed for the pitch, but coarse thread is not displayed.

Surface roughness
Surface roughness Ra1.6 Ra3.2 Ra6.3
Image
Set Value Ra1.6 Ra3.2 A reference surface roughness value is not displayed

Tip

  • The surface roughness value can be specified. See (1) to (6) in the figure to the right for surfaces for which values can be set.
表面粗さ値の指定が可能です。

Tip

  • The display of the dimensions of holes follows the guidelines listed below.
  • The display of the angular position of holes on the sides of the cylinder from the lathe machining is also added.

Notes

  • A hole located on the central axis is recognised as a “hole” supported for automatic quotation
