How to Use Elevation Hatch in BricsCAD BIM

Quick answer: Generate elevation fill is a section property that displays a composition’s texture or solid hatch when a 2D elevation generates, confirming and expanding the brief mention on this hub’s physical materials page. Hatches can also generate for other section types once activated in the Properties panel. A hatch generates for every visible boundary on the 2D elevation, including boundaries not perpendicular to the section, without perspective corrections. The union of elevation lines changes independently from the Union section setting, confirming exactly the same note from the physical materials page, both controlled in the Physical Materials dialog.

What “Elevation” Means Here

An elevation is a Section Plane in a 3D model with its Section type property set to Elevation, the same Elevation template covered on this hub’s BIM sections page, used to generate 2D drawings representing your model’s elevations.

Making Elevations

1. Create BIM elevations using BIMIFY.
2. Select the BIM elevation and choose Generate BIM Section from the Model command tab of the Quad.
3. Select it and choose Open BIM Section Model from the Model command tab; the section result displays in the layout viewport of the destination drawing.
4. Select the paper space viewport; its properties display in the Properties panel.
5. Under BIM, set Generate Elevation Fill to On.
6. Select the viewport and choose Update BIM Section from the Model command tab.
7. Optionally copy the viewport and set Generate Elevation Fill to Off on the copy, giving you two versions of the section result, one with and one without elevation hatch.

Configuring the Hatch

1. Type BLMATERIALS or BLCOMPOSITIONS to open the Physical Materials or Compositions dialog.
2. Click the composition, then double-click its pattern to open the Physical Materials dialog.
3. Go to the Appearance tab; the elevation hatch defaults to None. Click the elevation hatch button and choose a type: None, Solid, Linear, Predefined, or Custom.
4. Configure the hatch’s scale, angle, colour, and layer (type a name in the layer field, or click the arrow button to select one from the list).
5. To remove connection lines in the elevation between different solids of the same material, go to the Properties tab and set Union elevation to Yes; this works independently from the Union section setting.
6. After regeneration, the hatch appears on the elevation.

Frequently Asked Questions

Does Generate Elevation Fill only work with elevation-type sections? It’s the default use case, but hatches can generate for other section types too, once activated in the Properties panel.

Can I get both a hatched and a non-hatched version of the same elevation? Yes, copy the viewport and set Generate Elevation Fill to On for one copy and Off for the other.

Does Union elevation affect the Union section setting too? No, they’re independent settings, both configured in the Physical Materials dialog’s Properties tab.

Are elevation hatches generated with perspective corrections? No, they generate without any perspective correction.
