Lets make this table

The WCS will define the table base so the table has a plan in the x,y direction of the WCS, and stands up in the z direction.

First, rotate the co-ordinate system into the vertical plane, so that you can draw the table profile (which can be then rotated to create the table).

Rotate the UCS by 90 degrees through the x-axis

Choose UCS from the SETTINGS Menu

Choose or type X

type 90

You have created a new UCS where the x-y plane is standing vertically in the WCS, and all 2D commands will draw into this plane (in elevation).
You must now force the display to view a plan of this new UCS

Choose PLAN from the VIEW Menu

ENTER to accept the default

First draw a line from 0,0 to 0,800

Then using PLINE:

Start at 0,0
@125,0
a
@0,15
@-95,95
l
@0,175
a
d
@1,0
@0,25
d
@1,0
@0,50

d
@1,0
@0,25
l
@0,175
a
@150,100
a
@0,30
l
@-180,0
Return

You've created an axis and profile to rotate around it, but first create a new layer called TABLE give it the colour 1 - RED and make it the current layer.

From DRAW - 3D SURFS - REV SURF

Select the PLINE for the "path curve"

Select the first LINE as the "axis"

Accept the following two defaults

The profile is rotated around the axis to create a 3D model. Use DISPLAY VPOINT 1,1,1 to view the model as an axonometric.

Unfortunately the resolution is not fine enough for our purposes.
Undo back until the revolution is undone. You will now alter the resolution of the REVSURF command using the surftab 1 and surftab 2 variables.

From DRAW - 3D SURFS - REV SURF

Choose SURFTAB 1

Enter 20

Select the PLINE for the "path curve"

Select the first LINE as the "axis"

Accept the following two defaults

The profile is rotated around the axis to create a 3D model. Use DISPLAY VPOINT 1,1,1 to view the model as an axonometric.

Save this model as L10.DWG
