The short easy answer is that with solid modeling, forms are built-up by drawing outlines and protruding them into forms, as well as using other protruded outlines to cut forms. Often these shapes are more geometric overall, and solid modeling is usually used to create the internal details of products. SolidWorks is a solid modeler (but can create surface forms too)
Surface modeling develops shapes by stretching a "surface" between 3d curves that you individually create. With it you build forms by creating one small surface at a time, slowly creating the complete shape. The intersections between the surfaces are very controlled so they can be very very smooth or crisp like a crease. Usually the shapes are more freeform and sleeker than an object that was created with solid modeling, but some people are very good and the lines blurrr.. Alias is a surface modeler, but Solidworks can create shapes with surfaces too
olids modeler: Starts with a solid object. You add and subtract other solid objects to it. If you cut into it, you're left with your solid object minus what was cut out--just like in the real-world. It's all very rational.
Many solids modelers are "parametric" meaning you can go back and look at the list of commands you've executed since the start of your model (the "construction tree") and change anything (hoping your model doesn't "break.") Very useful!
Pro/E and Solidworks are the most popular.
Surface modeler: A bunch of infinitely-thin membranes defined by boundary curves. If you want, you can connect one membrane to another, creating a "water-tight" form that looks solid, but if you cut into it, it would be hollow and you'd have to patch the missing cutout piece (intersect tools are typically used to automate this.)
Surface modelers generally aren't parametric. There is no construction tree. It's very hard to change something you did and expect the rest of your model to update.
Why would you use a surface modeler then? Because it's more freeform, and historically, the tools have allowed you more control over the shapes of those "membranes" than if you were using a solids modeler. And because designers have been attracted to this, the user-interfaces tend to emphasize the freeform more than the solids-modelers, which cater to engineers.
Alias and Rhino are the most popular.
there are some other differences like parametric history and assemblies as well that make Solidworks a worthwhile software to complement your Alias skills...
To do surface modelling for plate / sheet structure items ( from plastics to metals to wood ........) and do assembly simulations etc. This can be done in several otehr packages like solid modelling / PROE etc but CATIA has distict features to use for sheet structures hence it gives an edge to use it in body frames etc in Auto industry.
The contact angle is the angle in which the liquid interface meets the solid surface. The contact angle should be as small as possible to have an effective penetrant material.
Solid timber is what you'd expect it to be - actual wood. When people say 'solid timber' they want to let you know that the piece of furniture is not made from veneered particle board/mdf etc which may look like solid timber to the untrained eye.
For a given outer diameter, the solid shaft is stronger, but it weighs more.For a given weight, the hollow shaft is stronger because it has a bigger diameter.due to less weight & less bending moment..............the resultant bending moment for a solid pipe is much larger than for a hollow one because of their weight difference
The volume of regular solid can be measured by multiplying the length, is width and its distance.
it is same as surface and volume ! a plane angle is 2D and solid angle is 3D
WHat is the difference between polyheron and platonic solid
What is the difference between solid and gas in terms of their fluidity
Adhesive forces is the attraction between a solid and liquid surface. The difference in strength is determined by the behavior of a liquid coming in contact with a solid.
is there a chemical difference between the solid and liquid states of nitrogen
Area is the measure of a two-dimensional space enclosed by a shape, and surface area is the sum of all the areas of the faces of a three-dimensional solid.
what is the difference between solid and hollow?
Submerged fermentation:" The organism which can grow under the beneath the surface of the medium is called " Ex.. liquid medium (Nutrient broth) solid state-fermentation : "Organisms which can grow on the surface of the medium is called solid state fermentation" Ex.. solid medium (Nutrient agar)
they will look different
there is no difference because a solid shape is a solid because its solid as if in hard so there is no difference. if you want you can still look it up on google or something. !
The main difference between a polygon and a solid shape is that polygons are two dimensional. In contrast, solid shapes are three dimensional objects.
Solid surface is plastic resins and ATH (a hydrate of aluminum powder). Quartz is solid surface and quartz chips. Granite is anything they dig out of the ground and want to sell you. Solid surface can be repaired, doesn't stain, the sinks are seamless,and the seams are usually invisible. And it has a warranty.
