Irregular 3D shapes

[bhl]

Could someone suggest a way of drawing an irregular solid? For example, if I wanted a "3D box" where the top face is in a plane such that each corner is at a different elevation yet the corners of the bottom face are at the same elevation.
Thanks,
B.L.

The only way you can draw an irregulator cornered box is using isometrics. You can address this function by right click the OSNAP button at the bottom of the screen or press [F3] on your keyboard, DS or SE or DSETTING or RM or DDRMODES at the command prompt to display the Drafting Setting dialog box Select Snap and Grid tab and check the isometric snap grid button and OK. Since X spacing relates to horizontal measurements, it is not used in the isometric mode. You can only set the Y spacing for grid and snap in isometric. Be sure to pick the Snap On (F9) and Grid on (F7) check boxes if you want Snap and Grid modes to be activates. Use the F5 function key or [Ctrl] + [E] to change the crosshairs to the angle needed. The 'isoplane can be used transparently to toggle between isoplanes. To draw nonparallel surfaces, you can change the angle of the crosshairs to make your task easier. Hope this helps - John

You could also draw the solid rectangular box, then slice it using a plane defined by the desired points.
