Creating new layers
« on: June 07, 2016, 05:35:52 pm »
How do you determine the name, color, and line weight of layers not listed in the AI ID Department Standards?

Hi Nate:

The ID standards file addresses standard layers that you may use for your projects in class and it is based on the NCS standards national cad standards) that many firms use. Still, our work in design is never fully " standard" and every project is different. You will need to make your own layers that may not be in the standards file as you address the customized needs of each project and determine how you'd like to organize and plot your information.

Layer names for layers you create yourself can be organized by category and letter name, just as the standard layers are. For example, "A" for architectural layers, "E" for engineering, and "I" or " ID" for interior design. These general categories can be applied, along with your own naming ins sensible fashion. For example, if you needed a special layer for upper kitchen cabinets, you could name the layer: ID-cabinets_upper . There are not always specific rules for everything you'll need to draft, so you'll use the general categories and your own common sense.

For colors, you can select a color if your choice for layers outside of the standards. You drawings are plotted in black and white, so colors are mainly used for easy recognition as you work. Rarely, you'll want to plot in color, sometimes for color coded installations for example... But in the large majority of jobs black and white is the preferred format...so select the color that works best for you!

For line weights, good drafters know that contrast is the key for line weights and that weights show " level of importance" as well as location. Heavier weights are for major structures, light weights for lesser important details. Heavy weights are used to show items close to us in section or elevation, and lighter weights show objects farther away. You'll use your knowledge of drafting and the objects you are placing in a layer to determine a reasonable weight based in these factors.

Drafting is part science and standards, and part art and work "by eye" using good representational skills, so there is no black and white answer to this question that fits every scenario. Use your good judgement and "eye" to determine how you'd like to set and show your custom layers and use your experience as a drafter. You'll then be sure to be in the right track!

I hope that gives you some good thoughts on approaching custom layers! Ultimately, It's all up to you as the drafter!
