# AutoCAD exercise: a round table and chairs

> Draw a round table with six chairs in AutoCAD: one chair, then a polar array round the table's centre, and its dimensions, step by step. Free online.

Draw a round table of 120 with six chairs, in centimetres: each chair a seat 44 by 40 with corners rounded to 4 and a back 8 deep, its front 8 from the table's edge. Draw one chair above the table and let a polar array place all six. The drawing's dimension scale is set for centimetres.

## The drawing

A round table of 120 with six chairs, in plan, dimensioned in centimetres.

## Step by step

The engine draws each step and writes its history as you would type it: the prompts in AutoCAD 2027's order, with the same option letters. After a command's first point, a typed point is measured from the last one, as dynamic input measures it, and the history writes it with @; \# measures from the origin.

### 1. Draw the table

On the Outline layer, [`CIRCLE`](https://mellowcad.com/docs/commands/circle.md) at `0,0`, `Diameter` `120`.

1. Draw the table

```text
Command: CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: 0,0
Specify radius of circle or [Diameter]: D
Specify diameter of circle: 120
```

### 2. Draw a chair

The seat, above the table: [`RECTANG`](https://mellowcad.com/docs/commands/rectang.md) with a `Fillet` of `4`, from `-22,68` to `44,40` further on. Then the back, with the fillet set back to `0`, from `-22,108` to `44,8` further on. [`RECTANG`](https://mellowcad.com/docs/commands/rectang.md) keeps its fillet radius until you change it.

2. Draw a chair

```text
Command: RECTANG
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: F
Specify fillet radius for rectangles <0.00>: 4
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: -22,68
Specify other corner point or [Area/Dimensions/Rotation]: @44,40
Command: RECTANG
Current rectangle modes:  Fillet=4.00
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: F
Specify fillet radius for rectangles <4.00>: 0
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: -22,108
Specify other corner point or [Area/Dimensions/Rotation]: @44,8
```

### 3. Array the chairs

[`ARRAYPOLAR`](https://mellowcad.com/docs/commands/arraypolar.md): pick the seat and the back, press Enter, give the table's centre, `0,0`, then `Items`, `6`. Each chair turns as it is placed, so all six face the table.

3. Array the chairs

```text
Command: ARRAYPOLAR
Select objects: 1 found
Select objects: 1 found, 2 total
Select objects:
Type = Polar  Associative = Yes
Specify center point of array: 0,0
Select grip to edit array or [ASsociative/Items/Angle between/Fill angle/ROTate items/eXit]<eXit>: I
Enter number of items in array <6>: 6
Select grip to edit array or [ASsociative/Items/Angle between/Fill angle/ROTate items/eXit]<eXit>: X
```

### 4. Dimension it

On Dimensions, [`DIMDIAMETER`](https://mellowcad.com/docs/commands/dimdiameter.md) on the table, placed inside, and [`DIMLINEAR`](https://mellowcad.com/docs/commands/dimlinear.md) for the top chair's width, 44, and its depth with the back, 48.

4. Dimension it

```text
Command: DIMDIAMETER
Select arc or circle:
Dimension text = 120
Specify dimension line location or [Text/Angle]:
Command: DIMLINEAR
Specify first extension line origin or <select object>: -22,116
Specify second extension line origin: @44,0
Non-associative dimension created.
Specify dimension line location or [Text/Angle/Horizontal/Vertical/Rotated]:
Dimension text = 44
Command: DIMLINEAR
Specify first extension line origin or <select object>: -22,68
Specify second extension line origin: @0,48
Non-associative dimension created.
Specify dimension line location or [Text/Angle/Horizontal/Vertical/Rotated]:
Dimension text = 48
```
