i just started working in a new office and they do things a little differently here. i am used to having multiple layouts in a single drawing with different layer manager layouts and just refreshing each one with respect to the appropriate tab. here they have a separate sheet for each drawing x-refed back. we are using civil 3d 2009 so it is project based and you have to close one drawing in order to open the next (ex. site plan over to grading plan) instead of just swithcing tabs. i know that you can change the settings to allow multiple draiwngs opened in project based but i just want to know what is more typical. it seems like separate drawings instead of separate layouts for each sheet in a set of drawings is very redundant and ends up creating a lot of extra drawing files.
thanks for the input
That depends on the use. You may find better feedback in the Civil3D area. For us, having a separate drawing per file allows us to throw a lot of low-cost manpower at a project to meet deadlines, whereas if we did multiple drawings per file all of those drawings would be bottlenecked at whoever is working on that particular file.
We have the same issue. Document control wnats us to use multiple drawing files and we want to use multiple layouts for road plan and profiles.
Based on my own experiences, I'd say that multiple tabs works great when the project is small and self-contained. I use that approach now on projects of up to 20 sheets, give or take a few.
But as the file gets larger (including the sheets), it can adversely affect the performance, and as time constraints become an issue, there can sometimes be problems with one CAD person having sole responsibility for meeting deadlines on that project. That's when individual sheet files start making sense. Another thing is it's sometimes the format the customer wants their CAD files in (I know Walgreens does). Believe it or not, it's a more "team-friendly" approach...
Good point about client requirements. Those are usually based around their document management system, which are frequently limited to one drawing per file/document. Among other reasons, for physically large project areas it allows them to send out multiple projects at once, piecing out only the affected drawings; if everything for that area is in a single file, then only one project can be worked on at once, and only by one company. A single small upgrade or as-build to match field conditions could conceivably hold up a much larger project.
Jason, this also depends on how your office deals with work flow. If they like to distrube the work around in a group to get the work done. If everything is in one drawing with layouts then only one person can work on the project at a time. If each sheet is in it's own drawing, then multiple people can work on different parts of the project. I have done both, but my preference is having individual drawings for each sheet. I have seen drawing get corrupted and if this happens in a project with multiple layouts, you could lose all your work or a good portion of it.
