Clip 1: Tolerancer: an introduction...

WinLens Tolerancer is designed to help you create sensible tolerances for your lens system [the design must be rotationally symmetric]

This clip provides a very quick run thru of the tools available to help in tolerancing:

  • Standard graphs from WinLens
  • Define performance requirements
  • Sensivity analysis - tables of data - linked to the graphs
  • Tolerance editors - statistical feedback & many tools for tolerance assignment
  • Monte Carlo simulations of a batch of lenses made to current tolerances - linked to the graphs
  • ISO 10110 drawings - editor and flexible preview - highly customisable

Clip 2: ISO 10110 drawings II: drawing options on preview form...

In the preview form we show how:

  • to use the zoom/pan options
  • to adjust the location of the default symbols and dimensions
  • to add extra text & symbols to this drawing [or all drawings]
  • to see the extra drawing for aspheric surfaces, and how to edit them]

Clip 3: ISO 10110 drawings III: customisation...

In this clip we will show you how to customise the drawing logo, layout, language & font.

So far we have worked with the default drawing, and showed how you can edit the tolerances, adjust the symbols and dimensions, and add extra symbols & text.  These extra symbols & text can be setup so they apply to all drawings, so that is a good start to customisation - but we can do much more.

Clip 4: ISO 10110 drawings IV: reusing tolerances...

There are a lot of possible entries that need to be completed for each drawing.  Even for a modest sized system, it would take quite a while to manually enter all values.

Tolerancer allows you to save much time by:

  • copying data from an element, a surface or a material
  • applying default sets of tolerances - either those hardwired into the program or those you have saved

We show how to do a copy operation, and then an apply defaults operation using two simple dialogs to specify:

  • the source of the data
  • exactly which tolerances are to be copied
  • the target[s] to receive the data

Clip 5: ISO 10110 drawings V: cemented components...

Tolerancer will generate assembly drawing for cemented doublets and triplets. 

These reference the appropriate individual parts drawings, but are specifically designed for cemented components.  There is a new parts list table, and you may specify:

  • overall thickness tolerance
  • centering tolerances for the surfaces
  • efl tolerance
  • cement details
  • notes for the surfaces & elements

We show how easy it is to move drawing reference and dimensional details on the drawing.
