Framework boat & train

Hi,I send you my last exercise I have done,with a framework simulating the hull of a boat or a passenger car in aluminum workers.I could not fix a flaw inherent in the modeling of Rhino on the one…Continue

Dialog box "Loads"
1 Reply

Hi,one question:dialog box of SnS, "Loads" what's the difference between "force vector for face" and"scalar force for face"?"Scalar force for face" is not redundant?Germano PecoraroGermano PecoraroContinue

Triangolar loads
1 Reply

Hi,currently you can only apply uniform loads;you should think of the triangular loads, such as occurs in the beam-wall connections (onplate).I designed a simple roof beams on four double-T and I had…Continue

Scan & Solve for surface and poly-surface.

Hello,I did some tests on a roof of a board of a yacht of 12 tons.During the construction of the glass-resin shell I found it very convenient to draw a pin surface, to which I added the skeleton…Continue

Vadim Shapiro replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"The offset SHOULD be smaller than the radius of curvature,  but sometimes the user is not aware of the imperfections in the surface due to geometric construction methods.    And things will get much more complicated if the offset…"

"SnS I have simply changed the style of design with Rhino and I'll explain.In the past when I learned to model, first with AutoCAD, 3DStudio, etc. and then the pair-Rhino Flamingo, 3D modeling was designed to call…"

"Yes,in the case of the roof of a vehicle or a boat, you can lock the edges of connectionbetween the two surfaces, while the load (vector x, y,…"

Kristoffer Josefsson replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"Thanks for your reply Vadim. I'm happy to hear it is on the TODO list. The scenario I'm in, and which I assume is a common one, is to model for example a thin shell, hence the offset must be smaller than the radius of curvature anyway,…"

Vadim Shapiro replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"Germano and Kristopher,  thank you for you very insightful comments.  You are both correct of course.  Offsetting is one of the more sensitive operations in most boundary-based geometric modeling systems -- such as Rhino.  Bug…"

"Yes I agree with you, Rhino does not always respond properly to these commands.For those who know how to use, you can use "Grosshopper", or…"

Kristoffer Josefsson replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"Yes, but unfortunately this doesn't work for all kinds of surfaces or meshes... but the distance field approach could probably be implemented inside SnS."

Germano Pecoraro replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"Yes,I solved this problem in the following mephod:1 - design of the roof surface,2 - from the Command window "means land", I selected "offset surfaces,"3 - I selzionato joystick in the "solid closed",4 - I typed the thickness;so I…"

Kristoffer Josefsson replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"I second this. A thin shell model should be able to work with a surface and a given thickness, since SnS works with just querying points inside a volume, the volume can be defined by a distancefield around the surface."

Germano Pecoraro replied to Jordi Bayer Resplandis's discussion 'Solve a model with more than 20000 mesh'
"You can try using the command "Offset Surface".I fear that an area as complex as yours is complicated.A compromise solution might be to:1 - divide the "snail " in sub parts2 - apply the command "Offset Surface"3 - Boolean union,4…"

Michael Freytag replied to Germano Pecoraro's discussion 'Framework boat & train'
"GP- If this part and loading is symmetric, I would perform analysis on just a quarter of the model.  Use Rhino's intersect command with a block to isolate the quarter that does not have geometric problems.  Apply partial restraints to…"

"Germano, Vector force allows you to specify the direction the force is applied.  A scalar force is applied perpendicular to the surface like a pressure, except SnS computes the pressure from the load you specify.  See this link for…"
