DRAWING SETUP

4. Other Drawing Requirements (Contd...)

g. Graphic Standards – Drafting standards and symbols shall be in accordance with the Graphic Standards.

h. Hatching – Do not use polylines with increased width for hatching. All hatching shall be associative. Hatching shall not deviate from AutoCAD defaults.

i. Layers – All drawing files shall be produced using layer names and layer name formats. When submitting drawings, no objects will be on layer 0 (zero) unless otherwise specified. Script files that turn on and off layers in order to produce different drawings within the same file are prohibited.

j. Layer Colors – Choice of layer colors is at the discretion of the contractor. Note: do not use yellow or bright colors (especially in hatches) for color plots on white paper. Such colors compete with the information conveyed by the drawing. Use of darker colors and half tones is recommended.

k. Linetypes – Contour lines, dashed lines, and other fonted lines shall be made of one continuous line segment and not of a series of separate line segments. If linetypes other than standard AutoCAD linetypes are used the LIN file must be provided with the submission. Use of toned or patched lines are acceptable for distinguishing between various types of work, such as new from existing, one phase from another, or background floor plans. Curved entities such as circles, arcs, and ellipses shall be created of one continuous line segment, except for entities that have to be physically constructed in a segmented fashion. These may be segmented to represent the joints in the actual construction.

l. Lineweights – Assign lineweights to layers. In the layer properties dialog box, select the lineweight of a layer. Once the layer lineweight is set, it applies to all entities on that layer.

m. Scale – Create drawing entities at full size. For example, a 10-meter wall will be drawn to 10 meter and a 36-inch column will be drawn to 36 inches. Drawings considered schematic in nature can be drawn to any scale. Some examples of schematic drawings are schedules, riser diagrams, schematic diagrams, and single line diagrams.

n. Plan Drawings – Create a separate model file for each drawing. Use sheet files to combine floor plans with non-plan information or multiple elevations. Do not combine several drawings such as elevations, sections, and details in one model file. When a floor plan is too large to fit on a single sheet at the desired scale use viewports in separate sheet files to show portions of the floor. DO NOT create individual model files for portions of a floor.
