21-8. Autocad Modeling Loft 3D Model

How to depict a transition from i object to but about other object inward AutoCAD?

The LOFT command on the MODELING toolbar serves to depict 2D drawings or 3D models, which has an irregular shape in addition to tin live joined yesteryear 2 nonlinear POLYLINE or regions that are non planar. (eg: when you lot desire to connect 2 Polylines to a 2D drawing or for example: 2 semicircles or squares inward a 3D model of an irregular shape.
You tin also run Command inward Command Line Prompt => LOFT

Conditions for working amongst the LOFT ascendancy are equally follows:

• - All lines must live drawn amongst the POLYLINE ascendancy (or if you lot depict regular lines thus you lot must connect them to a unmarried Polyline.)
• - Two objects that merge amongst this ascendancy must non live inward the same airplane (plan equally A4 paper) because they volition non live able to connect.

In this example, I volition connect 2 objects that are non inward the same plane. The start object is a semicircle in addition to a minute wavy Polyline.
The scarlet on the drawing is a path that volition connect these 2 objects.

I right away remind you lot to pay attending to Active Layer in addition to its color. After executing the command, the drawing volition live inward Layer that you lot laid equally active (not default).When nosotros prepared the objects to connect, you lot withdraw to click on the push for the LOFT command. The mouse pointer is transformed into a modest foursquare in addition to at nowadays needs to click on the start object, which is our semicircle in addition to click on but about other object in addition to it is a wavy Polyline. Notice that inward the Command prompt, you lot at nowadays convey a query equally to how you lot volition brand these 2 objects merge. I did it over Path, thus type "P" without a quotation in addition to click on i of the scarlet lines because it's the path to which our objects volition connect.

Command: _loft
Select cross-sections inward lofting order: 1 found
Select cross-sections inward lofting order: 1 found, 2 total
Select cross-sections inward lofting order:
Enter an pick [Guides/Path/Cross-sections only] <Cross-sections only>: P
Select path curve:
Command:

So our drawing at nowadays looks similar this inward the pic below

Or if nosotros await at Realistic View it looks similar this

How to depict a transition from 2D depict to 3D model inward AutoCAD.

If nosotros desire to depict a 3D object amongst a transition nosotros tin create this inward the next way. Take for example, equally inward the pic below, where nosotros convey 2 REGIONS (squares in addition to circles). You must live a portion if you lot are creating a 3D model.

Do the same equally inward the previous instance amongst the LOFT command.

Command: _loft
Select cross-sections inward lofting order: 1 found
Select cross-sections inward lofting order: 1 found, 2 total
Select cross-sections inward lofting order:
Enter an pick [Guides/Path/Cross-sections only] <Cross-sections only>: P
Select path curve:
Command:

And of course, if you lot cut both objects in addition to brand but about other 3D object, you lot tin SUBTRACT i from the other in addition to become this hollow 3D model.

Also piece of employment the ISOLINES command for lineament lines inward the lineament sentiment in addition to piece of employment REGEN inward the Command Prompt to refresh.

And lastly but about other instance of how nosotros tin brand a transition from i object to but about other object.
