Drawing walls #

Drawing Arc Walls #

Open the Arc Wall Tool #

• Go to Build Tool → Draw Walls → Arc Wall.
• Or press H (shortcut key).

Draw an Arc Wall #

1. Click on the grid to set the starting point of the arc.
2. Move the cursor and click to set the ending point.
3. Move the cursor outward or inward to define the arc curvature (radius).
4. Click again to complete the arc wall.

Arc Wall Controls #

• Adjust the cursor position to increase or decrease the curve radius.
• Arc walls can be drawn as Convex Arc (curves outward) or Concave Arc (curves inward).
• Real-time preview helps visualize the arc before placement.

Continue Drawing Connected Walls #

• After completing an arc segment, continue drawing from the endpoint.
• Arc walls can connect with straight walls and other arc walls.
• Snap points help create smooth and accurate connections.

Create a Closed Room #

1. Draw additional wall segments and return to the starting point.
2. The system automatically snaps and closes the shape to form a room.

Snap Features #

• ✛ Endpoint Snap: Snaps to wall start/end points.
• ◼ Midpoint Snap: Snaps to the center of a wall.
• ⁜ Intersection Snap: Snaps to wall intersections and corners.
• Tangent Snap: Helps create smooth transitions between arc and straight walls.

Drawing Assistance #

• Real-time Radius Display shows the arc radius while drawing.
• Arc Length Measurement updates dynamically.
• Angle Indicator displays the sweep angle of the arc.
• Snap labels appear automatically when available.

Editing Tips #

• Use Undo/Redo from the top ribbon if required.
• Use Zoom and Pan for precise arc placement.
• Select the arc wall to modify its radius or position later.

Best Practices #

• Press H to quickly start drawing arc walls.
• Use arc walls for curved rooms, entrances, facades, and feature walls.
• Watch the snap indicators for accurate connections.
• Verify radius and arc measurements before finalizing.
• Combine straight and arc walls for complex floor plan designs.

Drawing Site Areas #

Build Tool → Site Area (or) Select a Site Area shape from the Site Area menu.

On the Build panel, click on Site Area. You will see the following tools:

• Line (for creating custom site boundaries)
• Rectangle (for rectangular site areas)
• Polygon (for multi-sided site boundaries)
• Circle (for circular site areas)
• Ellipse (for elliptical site areas)
• Arc (for arc-shaped site boundaries)
• Spline (for freeform curved boundaries)
• Pick Lines (for creating site areas from existing lines)

Select the required Site Area tool to begin creating the plot boundary.

Site Area: Line Tool — Start Point & End Point #

1. Click anywhere on the grid to set the starting point.
2. Move the cursor in the desired direction and click again to set the endpoint.
3. A site boundary segment is created.

Drawing Connected Site Boundaries #

• After completing one segment, click again from the previous endpoint and continue drawing connected boundary lines.
• The drawing tool maintains continuity for easy site boundary creation.
• To complete a site area, continue drawing until you reach the starting point.
• The system automatically snaps and closes the boundary.

Rectangle Site Area #

1. Select Rectangle from the Site Area menu.
2. Click to set the first corner.
3. Move the cursor and click again to set the opposite corner.
4. A rectangular site area is created.

Polygon Site Area #

1. Select Polygon from the Site Area menu.
2. Set the required Polygon Sides value.
3. Click to place the polygon center.
4. Move the cursor and click again to define the polygon size.
5. A polygon site area is created automatically.

Circle Site Area #

1. Select Circle from the Site Area menu.
2. Click to define the center point.
3. Move the cursor outward and click again to define the radius.
4. A circular site area is created.

Ellipse Site Area #

1. Select Ellipse from the Site Area menu.
2. Click to define the center point.
3. Set the major and minor axis dimensions by moving the cursor and clicking.
4. An elliptical site area is created.

Arc Site Area #

1. Select Arc from the Site Area menu.
2. Click to set the start point.
3. Click again to set the endpoint.
4. Move the cursor to define the curvature and click to complete the arc.
5. An arc-shaped boundary segment is created.

Spline Site Area #

1. Select Spline from the Site Area menu.
2. Click multiple points to create a smooth curved boundary.
3. Double-click to finish the spline.
4. A freeform curved site boundary is created.

Pick Lines #

1. Select Pick Lines from the Site Area menu.
2. Hover over existing lines or boundaries.
3. Click the required lines to generate the site area automatically.

Snap & Precision Controls #

Zlendo automatically assists with accurate drawing. When you hover over a boundary segment, snap points will appear to help with precise placement.

Common Snap Point Indicators #

• ✛ Start/Endpoint Snap: Snaps to the beginning or end of a boundary segment.
• ⁜ Intersection Snap: Helps connect boundaries accurately at intersections.
• Center Snap: Helps align circles, ellipses, and polygons accurately.
• Real-time Measurements: Displays dimensions while creating site areas.
• Angle Indicator: Shows boundary angles during drawing.

Site Area Editing Tips #

• Use Undo / Redo buttons (top ribbon) if needed.
• Zoom and pan to adjust your view while creating site areas.
• Select a site area to modify its dimensions, shape, or position.

2D Drawing Best Practices #

• Use the appropriate Site Area tool based on the plot shape.
• Use Rectangle and Polygon tools for regular site layouts.
• Use Arc, Ellipse, and Spline tools for irregular site boundaries.
• Watch for snap indicators to ensure accuracy.
• Check live measurements while creating site areas.
• Close all boundaries properly to create a valid site area.

Adding Doors / Windows / Openings #

After making a room(s), the next step is to add items like doors & windows to rooms.
