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.

An option could be to leverage global variety with a work flow method

I believe we all agree modeling is not an issue, it is only the drawings. (except for perhaps units)

A rough example:

Design stage: if created in US, then basic drawings done in 3rd angle for example.

in WC, provide ample statuses for work flow stages ie design, design freeze, transfer, manufacture,  obsolete (or 10, 20, ...-50)

this way, the location responsible for product creation, can keep it localized to prepare product requirements to customer satisfaction.

Should a product be released, go to the manufacturing stage, otherwise, it dies here.

Manufacturing stage: models retrieved at location (via pdm); manufacturing drawings are then created to localized "flavor".

You will find there is going to be mind set differences in manufacturing too.

I refer to, for example ISO 2768, especially -2.  If you know this standard, you will understand what I mean.

This may be a solution or it may jog a thought.

Good luck!
