How To Use Unfold Surface For Autocad Program For Sale

Computer-Aided Design This is a place to talk about anything related to CAD. Share CAD related news, ask questions about CAD software, ask how to get into the business or show of your latest 3D model. Computer-Aided Design, or just CAD, describes the use of computer software to assist in the creation, modification, analysis or optimization of a design.

CAD software is used for creating 3D models, technical drawings and documentation for manufacturing of a product, construction of a building or civil works. I have been looking for a way to 'unfold' / 'flatten' / 'develop' compound surfaces into flat patterns, so I can cut them out and form them. This is typically used for making textile based products but also for advanced sheetmetal or plastic parts which is what I'm using it for.

I spent a couple months doing this manually by carefully measuring my 3D surface and drawing the plan in 2D, but this is highly inaccurate and I have to do it over several revisions to get it right. So I looked around and found 2 commercial plugins that do it: Solid3dtech.com makes one for $1000 that plugs in to Solidworks or Rhino, and exactflat.com makes one for $$$ for Solidworks. I don't want to jump into using one of those commercial packages just yet. It seems like something that might have some open source alternative to it, because it seems like a pretty straight forward algorithm to implement, like maybe I can do it directly from a triangle mesh or using several steps in Rhino or something.

They are very good at making boxes and brackets. Developing a compound surface is a bit more complex, for example if you were trying to unfold a spherical shell or a cone shell, or even more complex a hyperbolic surface, or other lofted curve. Inventor / Solidworks have the basic sheet metal tools, but can't do that type of unfolding natively, they have strict constraints on the types of surfaces they work with. It may be possible to rough it using FEA, I'm experimenting with that right now. I use Rhino, and have been working on similar problems (aiming at laser-cutting complex formed masks out of leather).

Here's a process I figured out recently which seems to work: • Take your surface and draw your seam lines onto it as curves. The Pull command is useful here. • Draw lines connecting between neighboring lines, keeping them perpendicular to the curves if possible. (And make sure none of them cross or come from the same point on the curves, this throws an error on the next step.) • Use the Sweep2 command. It asks for two curves to sweep between, and then prompts you to select the cross-sections. Select your line connectors, in order. • It should generate a developable surface in place.

Repeat as needed to fully cover your desired shape, then UnrollSrf. In essence, this process is a computerized version of the physical process used here: (that post being something I found which helped inform my process).

There are several commands within Rhino that can do flattening features. Bear in mind, their abilities to be accurate are extremely dependent on your geometry. It is up to you to judge whether or not they have deformed your shape unacceptably. From the Rhino wiki: UnRollSrf - makes a flat pattern from 3-D developable (curved in one direction) surfaces.
