section perspective
1. Setup (1 hour)
- Define what you want to show - 20min
- Select the whole building, add bounding box by using BOUNDINGBOX. Split the bounding box on the clipping plane to get a surface which is the extent of the model at the cut
- Extract a plane coplanar with the clipping plane, which is the intersect of the cut and the bounding box.
- Then type ORIENTCAMERATOSRF (invoke BETWEEN, let’s you select two points diagonally opposed on the plane to align to plane). This allows accurate orthogonal 1-point perspective aligned to bounding box plane of the building.
- MAKE2D of the building
2. Create + Clean Cut Line Vectors (0.5 hour)
- Create the cut lines of the floors and walls
- Use the previous cut plane (coplanar to clipping plane) and INTERSECTTWOSETS with the building model. This will yield all the “cut lines”.
To create the cut profile (outline), use CURVEBOOLEAN. Remember to remove interior voids. That makes all the cut lines as a polygon
Add these lines in Cut layer.
Alternative: For a clean model, you can also select all lines of the ClippingPlaneIntersection layer.
- Cleaning inside the cut lines
Select the new Cut lines, hatch (make sure it is solid)
Bring the cut outline above the Make2D of the building
- HATCH fill cut outline
- Export to Illustrator (Hatches export as solid fills) or Go to top view, MAKE2D again
3.A. Rendered layered section perspective (1 hour)
Tip
Make sure you do not have any open faces and only have solids.
- Open Vray Interactive on the locked Named View
- Open Vray Materials, choose the Countour channel (This changes the material set for the different layers to get the raster lines of which you can alter the width)
- Set color to white or grey to create undertone
- Set up the width to 0.5
- Render the cut-away model with the contour assigned to each material of the original model.
- The rendering product should have lines associated with each hard edge of the model.
- This image can be used directly as a backdrop for the section perspective.
- Export the render to Photoshop, update the lighting
- Add figures and trees in Photoshop save as PSD
- Export the
Cut lines to Illustrator and place the PSD as backdrop layer
3.B.1 All vector section perspective: clean up (3 hours)
Disclaimer
The timeline for cleaning lines in this workflow is specific to the complexity of the model used, simpler models might take less time, more complex ones might be better of using the rendered layer alternative.
- Clean all linework 3h
- Go room by room, floor by floor and correct all lines
- Go from floor and walls to columns and windows
- Change the layers of the lines sequentially
3.B.2 Organizing line work and populating the sections (2h)
- Change the layers of the lines to organize
- Turn off the cut line
- Select all of the lines and turn to layer Background
- Then work on bringing the foreground and the light background
Use a red as the color of the layer being changed into to see clearly what got changed or no
Tip
Keep the named view of the Make2D open in another tab to correct the linework
- Then turn layers on an and off to see what is front and what is back, to clean other lines as well (now Cut is in red)
- Populating the section 30min-1h
- MAKE2D of the furniture and figures
- Or add figures which are already in section and place them in the foreground
- TRIM lines between figures
- Final corrections 30 min
- Check final corrections
- Export to Illustrator and update linework if necessary
