Drawing pipe and drape

Use the Pipe and Drape Wizard to add lengths of drapery in your drawing. You can add default length and height of drapery, or specify custom sizes for your drapery panels, and define drapery properties such as color, texture, and material.

The several components in a drape line are shown in the graphic:

• Drape panels: These are the individual pieces of fabric that hang from the horizontal pieces of pipe called crossbars. You can specify the number of drape panels in each of the pipe and drape drawing methods. The default number of panels is three per section.
• Section: A section consists of a series of drape panels hanging from a horizontal pipe called a crossbar, which is supported on each end by an upright pipe. You can specify the number of panels per section and, based on the drawing method you choose, either the exact width of the section or the maximum width.
• Upright pipes: These are the pipes that stand on either end of each section in your drape line, supporting the crossbar pipes.
• Base plates: These are support plates for the upright pipes.

The Wizard offers you two drawing options:

• Draw: This option gives you the most flexibility when drawing your drape line. It enables you to specify the height, maximum width of a section, and the number of drape panels per section. When you click Finish, the Wizard returns you to the drawing where you can click and drag to draw as many drape lines as desired in whatever length required.
• Specify: This option enables you to define the height, width, the number of sections in your drape line, and the number of drape panels per section. This option enables you to either draw a new drape line section, or add to an existing drape line.

To draw pipe and drape - Draw method

Note: If you are adding a new drape section to an existing panel in your drawing, click the Midpoints snap tool first. This ensures that the new drape panel “snaps” to the existing one in the correct position.

1. From the Draw menu, choose Pipe and Drape Wizard.

Result: The Select Drawing Method window appears.

2. Click the Draw option button, and then click Next.

Result: The Draw Pipe and Drape window appears.

3. Select Create a New Drape Line option to create a new section of the drape line; or select the Add to an Existing Drape Line option to add the next section of the drape line.

Notes:

• Drawing a new drape line includes all uprights for the drape line.
• Adding to an existing drape line uses an existing upright as the beginning of the added drape line.

4. In the Height box, type the height of the drape line, or accept the default value of 15’0”.
5. In the Max. Crossbar Length box, type the maximum length of each horizontal pipe, or accept the default value of 10’0”. This value sets the longest length of the horizontal pipe in a section between the upright pipes. If you click to insert a section at a shorter interval than this value, WYSIWYG automatically adjusts the width of each drapery panel accordingly and a shorter section is inserted in the drawing.
6. Select the Min. Crossbar Length checkbox and type the minimum length of each horizontal pipe, or accept the default value of 1”. This value sets the shortest length of the horizontal pipe in a section between the upright pipes.
7. Select the Use Equal Crossbar Length/Space Upright Evenly checkbox to automatically set the same length for all the crossbars. If you clear this checkbox, then WYSIWYG creates drapery panels of equal size for all full-size sections, but resizes the panels in the last section accordingly if you choose to make this panel smaller.
8. In the Pipe Diameter box, type the diameter of all crossbars and upright pipes.
9. From the Base Plate drop-down list, select the size of the base plate support for the upright pipes.
10. Select the Add Base Plate Weight checkbox to add thickness to the base plate in Wireframe and Shaded views.
11. In the Drape Panels per Crossbar box, type the number of drape panels that you want to see in each section of the drape line, or accept the default value of 1 panel per section.
12. The default or previously set texture of the drape is displayed in the Drape Texture box. To change the texture, click the Drape Texture ellipsis button to browse and select a new texture from the Texture Select dialog box that opens.
13. In the Drape Description box, type additional user information or identification for the drape line, which will be displayed in Reports.
14. Click Finish.
15. Click in the desired spot in your drawing where you want to start drawing the drape line.
16. Move the cursor to the spot where you want the first section to end, and click. Then move your cursor to the spot where you want the next section to end, and click. You can draw as many sections as you like. When you are finished drawing your drape line, right-click and select Finish Pipe and Drape.

Note: For information on customizing the new drape line, see To customize drapery elements (color, material, and texture).

To quickly change pipe and drape wizard settings

This procedure shows you how to quickly change some of the structural pipe and drape settings for a selected drape line, such as the height and diameter of the upright pipes and crossbars. Use this procedure to customize the structural properties of a single drape line.

1. In your drawing, select the pipe and drape sections that you want to customize.To select multiple sections, press CTRL, and then click the appropriate sections.

Note: The sections that you select must have been drawn in the same way. For example, all drape lines created with Specify method.

2. Right-click and select Change Pipe and Drape Settings.

Result: The appropriate Settings window appears. Based on the type of drape line that you selected, a different window appears.

4. Change any of the settings that you see in this window. For help on any of the boxes, click in the box, and then press F1.
5. Click Finish to save and apply your new settings.

To customize drapery elements (color, material, and texture)

You can add custom color, texture and material to selected drapery elements (such as the front and back of the drape panels, the crossbars, upright pipes, the drape loops that attach to the crossbars, or the drape lines as a whole).

Notes:

• If you select multiple drape lines in your drawing, you can apply the same properties to all of them simultaneously through the following procedure. However, note that if you had already selected varying properties (for example, if you had chosen one color for the front panel of some drape lines, but another color for the front panel of others), or if some of the elements had no properties selected at all, then when you choose new properties in the following procedure, it applies to all drape lines selected, overwriting any existing settings that you may have saved.
• When you select multiple drape lines, the Appearance tab only lists the properties of selected elements if they are common across all drape lines. For example, if the front panel of all selected drape lines already has the same custom texture applied, and it is set to tile in one meter squared intervals, then these values are shown in the Appearance tab. However, if at least one of the front panels in the selected drape lines has a different custom texture value applied, the Appearance tab does not list the texture settings at all. If you choose new texture settings, your choice overwrites all existing settings for the selected element across all selected drape lines.
• You can apply the same properties to all drapery elements by highlighting “Group” in the Elements box.

1. In your drawing, select the pipe and drape sections that you want to customize. To select multiple sections, press CTRL, and then click the appropriate sections.
2. With the desired sections selected, right-click and select Properties.

Result: The Properties window appears.

3. Click the Appearance tab.
4. In the left pane, click the drapery element that you want to customize. For example, to customize the front of the drape panels (each panel is double-sided), click Drape Front.

Note: You can select multiple elements by pressing CTRL, and then clicking the elements; you can select all elements by clicking Select All.

5. You have a choice of applying one of the following settings to the selected elements:

• Layer Rendering Color: Select this option to apply the same color as the current layer to the selected elements.
• Custom Color: Select this option and click the color box to apply a custom color. In the resulting color dialog box, select the custom color that you want to use, or click Define Custom Colors to create your own color.
• Texture from Library: Select this option to apply a custom texture file from the WYSIWYG library to the selected elements, and then click the ellipsis button (...). In the resulting dialog box, navigate to and choose the desired texture.
• Image Source: Select this option to apply a custom texture file that you have created and saved in either .bmp, .jpeg, .png, or .gif format. For information on image sources, see To create a new image source in the Image Manager.
• Video Source: Select this option to apply a video source or a subsource as a “dynamic texture”. Choose a previously created video source or subsource, or create a new video source or subsource. For information on video sources, see Video Manager.
• Use Normal Map: Select this option to apply an Image Source that is a Normal Map, to create the perception of fragmented surface texture detail and depth, making objects look more realistic.

Select from the drop-down list an existing Normal Map image or click New to create a new Normal Map image via the Image Manager.

Note: This drop-down lists all Image Sources that appear in the Image Manager; as such, Image Sources which are Normal Maps should be named appropriately for easy identification.

• Scale: Select the height or depth of visual effect created by the Normal Map. Select from the drop-down list, the percentage scale value from not visible (0%) to maximum value stored in the imported Normal texture/image (100%).

6. If you have chosen to apply a texture to the elements, you can choose how the texture will appear on the selected drapery elements as follows (if you have applied a color instead, you can skip directly to step 7):

• To view the texture file as a series of square or rectangular “tiles” that are repeated over the entire surface of the drapery element, click the Tile option button, and then type the size of the tiles in the boxes provided.
• To view the texture file stretched out as a single surface over the entire drapery element, click the Stretch option button.
• To preserve the aspect ratio of the texture so it is not distorted when stretched over the element, click Keep Aspect Ratio.
• To choose a custom border color for the texture when it is stretched over the surface of the element, click the Border Color box, and then choose the custom color.
• If you have selected Use Normal Map, specify the number of times the Normal Map is multiplied across the object (element) to which it is applied. Type the value in the Normal Map Size Multiplier box. (Enter a valid number between 0.01 and 100.)

Notes:

• The default value of 1 results in no changes to the Normal Map’s size; values lower than 1 will increase the size of the Normal visual effect, and values higher than 1 will decrease it.
• The Normal Map Size Multiplier operates within the Tile or Stretch Texture Options.
• To set the angle at which the texture appears on the drapery element, type or select the value in degrees from the Rotation (Deg.) drop-down list.
• To change the color of the texture, click the Color Tint color box and select a new color, then click the Scale drop-down list box to specify the intensity of the color.

7. To choose a custom material for the selected drapery elements (such as metal, paper, plastic, or fabric) click the ellipsis button (...) in the Material Properties section.
8. In the resulting dialog box, navigate to and highlight the desired material, and then click Select.
9. Click Apply.
10. You can apply a transparency level to the selected element. Based on the settings that you have chosen for color, texture, and material, the transparency options vary as follows:

• Transparency: This setting controls the proportion of light that passes through the material. All materials in WYSIWYG specify a level of transparency that varies from one material to the next. For example, glass is more transparent than brick. If you select Default, the transparency level is set to 0% (opaque).
• Specular Level: This setting controls how prominent other specular effects appear on the material.
• Specular Gloss: This setting controls the level of gloss the material will project.
• Specular Color Source: This setting controls the amount of light that is projected on the material.
• Light Reflection: This setting controls the amount of light that is reflected off the material.

Notes:

• From the drop-down lists, change any of the material properties. Use the Reset button to revert back to defaults.
• The beam will pass through a surface with the Transparency value set to 80% or greater. The beam will not pass through the surface when the value is lower than 80%.

11. Select Display Reflection in Shaded Views checkbox to display the set reflective characteristics in Shaded Views.
12. Click Apply.
13. Click OK to save your changes and close the Properties dialog box.

To customize pipe and drape structure for individual drape lines

This procedure shows how to the structural properties of individual drape lines that you have selected.

Note: While the tabs in the Properties window are best used to customize a single drape line, if you have selected multiple drape lines, the values that you type in these tabs apply to all selected drape lines; they overwrite any custom settings that you may have previously saved for individual crossbars, uprights, or drape panels.

1. In your drawing, select the pipe and drape section that you want to customize.
2. With the desired section selected, right-click and select Properties.

Result: The Properties window appears.

3. On the Properties window, click the Pipe and Drape tab.
