Title: 3D Model Continuous Perimeter Flatshot
Post by: Matthew H on January 24, 2020, 04:30:56 PM
I am trying to find a faster way to get the continuous perimeter of a projected 3D model.

Currently I use three different ways to generate the boundary/perimeter of a 3D model.

The first way is to FLATSHOT the 3D model, then manually trim all entities till the perimeter is left, this method is tedious.

The second way is to FLATSHOT the 3D model, then use the following lisp routine from Lee Mac to generate a boundary/perimeter. This method works well on non complex flatshots.

http://www.lee-mac.com/advpolyoutline.html

The third way is the quickest. FLATSHOT the 3D model, then draw a bounding box around the geometry. Hatch all open areas. Once the hatch has been created you can then run the command HATCHGENERATEBOUNDARY, still requires some cleaning.

I have posted a simplified example. Most drawings are much more elaborate.

If anyone has any advice on a better method I would greatly appreciate it. I think part of the issue is there are minuscule gaps that get created during a flatshot.

I like solview and soldraw combo myself.

Did you know BricsCAD has a feature "preserve entity layer" in the flatshot command.
This way you can still identify the parts. Works for me.

Print to PDF as hidden line, then import PDF to linework.

I'm struggling to see a context for this though.

Only thing I donít understand is briscad isnít all they innovative... is a software trying to be a copy of another software. We really need something no one has thought of yet

At the risk of going further off topic :)
BricsCAD has 'built in' Sheetmetal, BIM (think Revit), Civil, Mechanical (think Inventor), parametric mdoelling and some built in AI and it's all native .dwg!
I think that's pretty innovative ;)

But, back on subject, Bricscad does have the ability to create user views with various line work using the Mechanical workspace view creation commands.

I don't see these options in Autodesk AutoCAD. Innovative as in combining and move ! forward ! Not standing still year after year.
