3D Properties

Controls how objects are created, and their materials.

Note: For options that control how 3D objects are displayed, see ACIS.

The ACIS engine is Available in DoubleCAD Pro only. Therefore, you can only work with solids and surfaces in the Pro version, though DoubleCAD surfaces are available in all versions.
*Cre ate 3D Object As:* Choose between Solid (ACIS representation) and TC Surface (DoubleCAD representation). 3D objects are created as solids by default, but you can change this Properties setting for all 3D tools, or for individual objects.
Solid objects are created using the ACI S solid modeling engine. Solids are more realistic than surfaces, because objects have volume as well as shape. The solid model assumes that a 3D object comprises a framework, a "skin" (set of surfaces) encasing the framework, and inner "body."
TC Surface objects are created using the DoubleCAD internal graphics engine. The "inner body" concept does not apply to surfaces, but when an object is trimmed or cut, the resultant object is entirely covered by surface elements.
You can create surfaces that are ACIS objects by converting existing objects. See Surface and Solid Conversion Operations.

Tip: You can explode a solid object twice to turn it into an exploded (node-editable) surface object.

Thickness: Relevant for 2D objects. Assigning a 2D object a thickness makes it a 3D object. Closed 2D objects become solid or surface volumes; open objects (lines, arcs) become surfaces. See Creating 3D Objects by Editing 2D Objects.

Note: The thickness is assigned perpendicular to the workplane in which the object was drawn, regardless of the current workplane.

Materials: Apply photorealistic colors and textures to the selected 3D object (your model) by using preset materials or by creating new materials. Materials can also be assigned By Block. When set By Block the object will use the material assigned to the block instance in which it resides.
Materials are only viewable in certain render modes. See Materials.
