Question

Drawing View Orientation - 1st vs 3rd Angle (Globally)

Today my company has the requirement to create multiple drawings of the same model to support 1st and 3rd angle projection requirements in multiple factories.  I am seeking others input as to how companies may have handle this situation as it is duplicate work.  While a config option change allows for new view to be created in a different orientation, it does not update or change those views already on the drawing.

This seems quite simple as globally the company should decide on one angle of precision, but are there other options?  I have heard the term "declared" views, but ASME Y14.3 does not specify the use of these, nor can I find documentation online to support this theory.  Maybe they are technically known as something else?

Just looking for other opinions or suggestions.

Thanks much!

Brian

First of all, a model does not have defined "views", only the drawing does.

With that being said, it is conceivable to create two separate drawings that point to the same model.

One drawing could use a first angle.dtl while the other uses a thirdangle.dtl.

Units could possible be troublesome if they need to be different...

There is a third option - view arrow method.

I agree 100% with Ben, the requirement is not driven from local standards, it is a culture one has been used to and trained on for years.  I imagine for those companies that have been successful with this, management has taken the stance to adopt one method and made sure appropriate training was provided "globally" to all manufacturing facilities.

Today our design facilities are rouge.  We are attempting to globally work out of one PDM system, using the same version of Creo.  We are also deploying a method that includes only ONE model with multiple drawing variants as needed.  The base or first variant is typically in English and 3rd angle projection.  A local variant could be Chinese with 1st angle projection.  Another could be Spanish in 3rd angle projection.  Another could be French with 1st angle projection.

Using the proper methods, standard symbols, standard notes, standard formats we can automate the creation of these variants to almost 100% (almost because placement of notes and translations may utilize more room on drawing).  When you throw in angle of projection, my success rate drops considerably because it only switches the drawing setup option.  You basically have to recreate all the views in the new projection.

We have been struggling, but it seems I will need to put together these examples and let management find a cure.

Thanks for the responses folks!
