Hello guys! Is there a command for welding two end points of two separate curves that are apart from each over, without using the mouse dragging and osnap. Thanks a lot!! If it is just curves, you can turn points on and drag one end curve point to the other. If you need the in-between area like in T-Splines when you select both points first then hit the Z key, I would probably draw a straight line between the ends I want to join, then turn on points for both curves and drag one to midpoint of the straight line then drag the other curve end point to the first line midpoint curve.
It also helps if you post images of what you are trying to achieve. I am just going by the T-Splines command here. Thanks for the answer, what i want actually its quite simple: Nov PM. I want to avoid using dragging and osnap or making extra geometry, my goal is time saving. I was just giving some work arounds. If you really need the weld, then alt drag your curves up with T-Splines arrow to create a t-splines surface, weld the points, convert surface to NURBS then duplicate edge.
This will give you the welded lines. Sometimes what seems like taking more time at the start will actually save us more time down the road when modelling. Match using Position setting… But in this case, maybe the Connect command is probably what you really want. Match dialog box.
Thanks Doug, I have been using Match curve more and more, but always the little things that make the biggest difference. If the lines are coplanar you can use the Fillet command with the fillet diameter set to 0. It will extend or shorten one or both of the lines until they intersect. There is an option to have them joined as well. I knew the fillet trick from AutoCad and never looked further. Weld end points of 2 curves Rhino for Windows.
Hello- I think you want the Match command. Am I missing something in the Match command? I get this from 2 straight lines. Thanks for the Connect command, that is neat.I used Insert items with no 1. So I expect a list where every second element is from the another list.
No idea yet. Share Tweet Facebook Facebook. Views: On List 1 I have 3 Index 0,1,2 for corner points and on list 2 I have 3 branches with 1 index 0. Of course when I combine these points to lines there are a whole set of multiple lines and the List is quite messed up. This is when I generate the points from 1 mesh.
Imagine to use multiple items to get information from. I assumed something Series too, but it seems some of my settings was not proper however I can see now, great. Sign Up or Sign In. Added by Parametric House 0 Comments 0 Likes. Added by Alphonso Peluso 0 Comments 0 Likes.

So you either need to rotate CPlane in position normal to projection, or use some Ortho view ie.
Front, Left, Right…. In this case, we will use the curve we projected in the previous step to Trim the surface which will create a hole. By the way, I strongly suggest you check this link to see all the possible uses of Trim. Sometimes you have a line curve laying directly on the surface maybe you extracted it from the surface — see below, or projected it onto it….
FilletEdge is a complex command that can round the sharp edges between the two surfaces. Note that the radius of the curvature can vary not in this example. See more info about this command hereespecially if you get bad results.
At the corners of the edges you select, you will see handles that define how big the curvature radius will be at that point in this case, all the points will have radius 0. You also see the actual curvature line, which helps you anticipate results. With this option on, everytime we select an edge, Rhino will automatically select all connected edge. However, sometimes, as in this video, an edge may have several connected edges, so we need to tell Rhino which one we want.
Polysurface is an object that contains more than one joined surface. Here how we can extract one of the surfaces from such objects — there are different reason why we may need it. For example, we may want to open the extruded solid on one side, like below:. We already seen how we can use Trim to punch a hole in a surface.
When you are modeling in Rhino, it is very likely that you will be modeling it piece by piece, creating different surfaces for different part of the object. That way I am making sure that both Surface 1 and Surface 2 share the same edge ellipse projected to Surface 1. Note that I need, before joining, to actually Trim surface 1 using the ellipse — so that both surfaces are open. In order to join the two surfaces that share the same edge — well, you use command called Join same one that joins the lines that share the same point.
More on that below. In order for Join to work, edges that the two surfaces share must be perfectly the same. Sometimes they look the same, but in fact they are not. What it means is that although we used the same projected ellipse to create the loft object, Loft command itself has changed the ellipse slightly to make the object smoother.
In this case our best bet is to use BlendSrf command that will add another surface between the two separate edges. This surface can be smooth, continuing the curvature of both objects, or it can be straight — depending on blending parameters.
In order for this to work, both surfaces need to have open edges that are -ideally- of similar shape and relatively close by.
Sometimes the selection of edges will not be as straightforward and easy as in the previous example.ADVANCED RHINO / SOFT EDIT SRF / POINTS ON
Instead, we may need to select many different edge segments one by one. Boolean operations are the ways to use two 3D objects to create new one by one of the following methods:. Since this sounds confusing, better check the video. More information on Boolean: S ince Boolean operations sometimes can give unpredictable faulty results, read this carefully if you see problems. Important Note : Boolean operations can create dirty inaccurate meshes, so use them sparingly.
For example, the object we created in this video using Boolean elliptical cylinder with holes would have better be done in this way:.
In Rhino, all surfaces are infinitely thin — they have no depth. In order for Shell to operate, it will ask us to remove some of the surfaces of the closed solid. See example, Shell command performed on the object we created in one of the previous steps using MakeHole command. See how the resulting object after removing of the selected surfaces now have a thickness, a depth to it.
Another way to add depth to surfaces, which is used more often than Shell, is to offset surface using OffsetSrf command.There are no limits on complexity, degree, or size beyond those of your hardware.

As you may know, the Rhino development project started nearly 20 years ago to provide marine designers with tools for building computer models that could be used to drive the digitally controlled fabrication equipment used in shipyards. We continue to focus on the fact that designs are only useful once they are built and in the hands of consumers. With the cost of digital fabrication and 3D printing technology dropping quickly, more and more designers now have direct access to 3D digital fabrication equipment.
While we are not experts on all the many fabrication, manufacturing, or construction processes, we do focus on making sure that Rhino models can be accurate enough for and accessible to all the processes involved in a design becoming a reality. Robust mesh import, export, creation, and editing tools are critical to all phases of design, including:. Both new and enhanced mesh tools, plus support for double-precision meshes, accurately represent and display ground forms such as the 3D topography of a large city.
Capturing existing 3D data is often one of the first steps in a design project. Rhino has always directly supported both 3D digitizing hardware and 3D scanned point cloud data. Rhino 6 now supports:.

Many modeling programs don't allow you to set your tolerances. They are determined for you whether you like it or not. Rhino gives you the advantage of letting you set your own tolerances according to your needs, but it takes a bit of experience and understanding to set them correctly.
Tolerance is simply a way of stating how much precision you need, or conversely, how much error you are willing to accept in your project. Different projects and sizes of objects will have widely varying needs for accuracy. You wouldn't build a building to the same level of micron precision as a Swiss watch, and the inverse would be equally ridiculous that is to say impossible. Engineering methods for specifying tolerances are precise and involved.
We will not go into that kind of detail here. We are simply a guide to set up your projects for modeling in Rhino.
Depending on which template you choose currently, Rhino sets your absolute tolerances at 0. You can also create your own templates with other tolerances. But what does absolute tolerance mean, really? In Rhino's terms, the absolute tolerance setting dictates the greatest permissible distance apart that two objects or elements can be and still considered close enough.
Close enough means that two surfaces or curves are capable of being joined or that an approximate operation like a sweep will generate a surface whose edges follow the rails to within the specified absolute tolerance.
Some objects are possible to define mathematically perfect to the limits of what your computer's floating point math is able to calculate. Generally, you don't need to worry about extremely tiny tolerances. Yet, some commands rely on approximations to fit or match curves or surfaces to other curves or surfaces. The more exact solution you need, the more time it takes to calculate, even to the point of locking up your computer. The absolute tolerance tells Rhino at what point you think it's good enough and to stop trying to calculate a closer solution.
Another downside of specifying a higher than needed absolute tolerance is that Rhino will then generate things like sections or intersections with many, many control points. Control points which are heavier bigger data sizenoisier not as smoothand harder to edit. Any command necessary to find the intersection between curves and surfaces is an example. So, why don't I just model with loose tolerances? The advantage of a looser larger tolerance is that computing time and data size may be reduced, but at the expense of your model's accuracy.
This is precisely why you need some experience to set your tolerances. It is always necessary to find a good compromise. For example, the Intersect command creates a curve at the intersection of two surfaces.
The curve is guaranteed to lie, within the absolute toleranceon each of the two surfaces. Try the Intersect command and save the resulting curve off to one side.
Then add a zero to the tolerance setting and run Intersect again.Logistic regression seeks to learn the coefficient values b0, b1, b2. Xk must be numeric values. To adapt this model to all the datatypes that BigML supports, we apply the following transformations to the inputs:BigML.
You can also list all of your logistic regressions. Value is a map between field identifiers and a coding scheme for that field. See the Coding Categorical Fields for more details. If not specified, one numeric variable is created per categorical value, plus one for missing values. This can be used to change the names of the fields in the logistic regression with respect to the original names in the dataset or to tell BigML that certain fields should be preferred.
All the fields in the dataset Specifies the fields to be included as predictors in the logistic regression. If false, these predictors are not created, and rows containing missing numeric values are dropped.
Example: false name optional String,default is dataset's name The name you want to give to the new logistic regression.
Example: "my new logistic regression" normalize optional Boolean,default is false Whether to normalize feature vectors in training and predicting. The type of the field must be categorical. The type of the fields must be categorical. The range of successive instances to build the logistic regression.
Regularizing with respect to the l1 norm causes more coefficients to be zero, using the l2 norm forces the magnitudes of all coefficients towards zero. Example: "l1" replacement optional Boolean,default is false Whether sampling should be performed with or without replacement. The minimum between that number and the total number of input rows will be used. Example: 1000 tags optional Array of Strings A list of strings that help classify and index your logistic regression.
By default, they are "one-hot" coded. That is, one numeric variable is created per categorical value, plus one for missing values. For a given instance, the variable corresponding to the instance's categorical value has its value set to 1, while the other variables are set to 0.
Using the iris dataset as an example, we can express this coding scheme as the following table:The parameter value is an array where each element is a map describing the coding scheme to apply to a particular field, and containing the following keys:The value for coding determines which of the following methods is used to code the field: If multiple coding schemes are listed for a single field, then the coding closest to the end of the list is used. Codings given for non-categorical variables are ignored.
The dummy class will be the first by alphabetical order. This is because the default one-hot encoding produces collinearity effects which result in an ill-formed covariance matrix.Since the 1990s, perfumes have known an inflationary spiral.

Gartner analyst Valdis Filks believes that solid-state arrays (SSAs) will improve in performance by a factor of 10, and double in density and cost-effectiveness within the next year. This is destined to change the dynamics of the storage market. And from there, he sees many years of further expansion. Further, price erosion will probably reach a level to allow the complete substitution of SAS hard disks, reducing the usage of hybrid systems to usage areas that focus on the lowest costs per capacity and which do not have high-performance requirements.
SSAs are emerging as the general preference to hybrid arrays and as a clear replacement for aging disk arrays.
Vendors are innovating with various form factors and technologies such as PCIe, NMVe and 3D XPoint. NVMe is a much-needed update to data transport mechanisms created in an era when Internet users were happy with 28k dial-up connections, This brings the communication channels around storage closer to the velocity of modern processors and flash architectures.
NVMe also excites Jeff Boudreau, president, Dell EMC Storage Division. He notes that although we are still in the early days of real NVMe usage in storage, it will become the industry standard in five years. Storage class memory (SCM) is a general term that may include specific vendor offerings such as 3D XPoint, ZSSD and others.
It is also referenced sometimes as persistent memory (PMEM). This memory technology promises to be 10 times denser and up to 1000 times faster than conventional flash. Jeff Baxter, chief evangelist for ONTAP at NetApp, agrees that the new possibilities offered by SCM and NVMe are disrupting the market and fueling innovation.
