Elevation Hatch

Overview: In this lesson, you will learn how to generate textures or solid fills in a 2D elevation.

Lesson objectives:

After completing this lesson, you will be able to:

• Make elevations
• Generate textures or solids fills on a 2D elevation
• Change the hatch, scale, angle, line type, line weight or color of the textures or fills

About Elevation Hatch

'Generate elevation fill' is a property of a section plane that can display the texture or solid hatch of a composition when a 2D elevation is generated. Hatches can also be generated for other types of sections when activated in the properties panel.

The hatch is generated for every visible boundary on the 2D elevation including boundaries that are not perpendicular to the section. Hatches are generated without perspective corrections. The union of elevation lines can be changed independently from the 'union section' settings in the physical material dialog.

Make elevations

Note: 'Elevation' here refers to a Section Plane in a 3D model that has its Type property set to Elevation. This can then be used to generate 2D drawings that represent the elevations of your model.

1. Create BIM elevations by using Bimify.
2. Select the BIM elevation and choose Generate Section in the Model command tab in the Quad.
   
3. Select the BIM elevation and choose Open BIM Section in the Model command tab in the Quad.
   The section result displays in the layout viewport of the destination drawing.
4. Select the paper space viewport.
   The viewport properties display in the Properties panel.
5. Under BIM, set the Generate Elevation Fill property to On.
6. Select the viewport and choose Generate Section in the Model command tab in the Quad.
7. (option) Copy the viewport, then set the Generate Elevation Fill property to Off to create two versions of the section result, one with and one without elevation hatch.

Configure the hatch

1. Go to physical materials dialog by typing BLMaterials or BLCompositions (1) into the command line.
2. Click on the composition and double click on the pattern of the composition to open the physical material dialog (2).
   
   
   
   
3. To configure the texture or solid fill, go to the appearance tab page (3). The elevation hatch is set by default to 'None'. Click the elevation hatch type button and select the type of hatch: None, Solid, Linear, Predefined or Custom (4).
   
   
   
   
4. Configure the hatch. Define the scale, angle, color and/or layer of the pattern. (5)
   Note: type a name in the layer field or click the arrow button and select a layer in the list.
   
   
   
   
5. To remove connection lines in the elevation between different solids of the material go to the properties tab (6) and set Union of elevations to 'Yes' (7).
   Note: Union elevation works independently from the union section setting.
   
   
   
   
6. After regeneration, the hatch will appear on the elevation.
