Part of the Wittur Group since 2016, it manufactures and supplies various elevator components such as automatic elevator doors, entrances, cabins and door operators.
Sematic started out in 1959 when its founder Francesco Zappa formed a company for producing elevator doors known as the Zappa company in Cinisselo Balsamo, Milan. In the 1960s, after expanding itself to several northern Italian cities, the company formed a partnership with West German elevator company Lift Munich (now Liftmaterial) in an effort to expand its products to other European markets; under this arrangement, Zappa would produce elevator doors and Lift Munich would sell them to other parts of Europe. Also in the 1960s, Zappa along with other Italian partners formed Semag (Sistemi per Elevatori Montactichi ed Ascensori in Genere) as a distributor of Zappa's products in Italy and other countries worldwide.
In 1968, Zappa created its own fully automatic doors with AC motor known as "Sematic", a name coined by combining the words "Semag" (its distributors) and "automatic". Five years later, the company relocated its headquarters to Osio Sotto, Bergamo where it still resides today.
In 1982, company created the Sematic 2000, an automatic door with built-in electronic controls which replaced the previous arm driven mechanism with a new belt driven mechanism. In 1988, the company entered the UK market and later the North American market in 1993. It later acquired American elevator components manufacturer W.S. Tyler Company in 2000.
On November 9, 2000, the company was restructured and became Sematic. In the same year, it took over Liftmaterial from Schindler, who previously held the company from Haushahn since 1998[1][2].
On August 11, 2015, Sematic signed an agreement on the transfer of a controlling interest with Wittur Group in order to create a leading global supplier to the elevator industry[3]. In February 2016, Wittur Group acquired Sematic[4].
I have been using Webflow for several years to build front-ends for web apps. So far I have always exported the site and with a lot of manual work I created Vue.js / React.js. components out of my exports.
It seems that there are already good solutions to build web applications with authentication and memberships. (Like Memberstack or Firebase Auth)
However, there is still no easy way to create a web app with dynamic and editable user data.
The only truth in this article is that WF is great for rapid prototyping capabilities. Of course you can do it in some way but it is more hassle than joy and nothing changed since last response (3 years ago). You can build a dinning table only with axe but you will get more appropriate, enjoyable and better result when use correct tools for job.
Anyone doing MBD with UDFs? Are you aware of a work around for having the annotations placed on a different annotation plane? I know once it is placed you can right click on them and choose move to plane but I am hoping there is a better response.
We are not using this in the context of MBD deployment but tried to exploit it for drawing purposes. I know that MBD is intended to get rid of 2D drawings, but so far have not encountered an organization that has deployed MBD for production work.
I have seen issues with annotations displaying properly when included in UDF for a model and then presented in 2D drawing. It was all "fixable" but required manual intervention for each drawing view when placed. Our intent was to define the UDF and then drop into the model where needed and hoped that the drawing view would be "good" when we added a view and showed the annotations. Our hope was crushed by PTC when we inquired about this......
No doubt MBD has challenges but there are organizations using it full stop. Aero structures for instance are defined by laminar flow and there isn't really another good way to make them without MBD. We are not doing MBD in the "grand vision" mentality but the great thing about UDFs if you can setup all of the sematic references and GD&T once and then reuse and they copy forward. If you are going to be creating UDFs anyways there is no reason not to try and take advantage of that functionality for the future.
When you said that after you placed the UDF you use right click-->move to plane, which is one possible command, but did you also considered using the Change orientation which is also available in the right click menu?
Using this command you will be able to not only move the annotation to a plane that is parallel to the already used annotation plane in the UDF, but also to choose totally different annotations plane like TOP, FRONT, LEFT etc.?
Ideally the UDF would allow the annotation plane as a choice for the user (so all of the annotations would move to that plane) or even better, just auto re-align the annotations parallel to the annotation plane that the geometry is being placed on.
In my case, simplistically, I have a hole with some GD&T. The default dimension for the original hole is oriented to the surface that the hole is being placed on. Yet when the UDF is made the new annotations are not being placed on the surface of the new hole in the new part where the UDF is being placed. The annotations keep the orientation from the original part that the UDF was made from.
PVS 5.0 is a significant new release of PVS. The highlights include anSBCL port, the incorporation of the PVSio, Manip, Field, and ProofLitepackages from NASA, a new theory interpretation implementation, newjudgement forms, new support for Yices, and several bug fixes.
Note that we are no longer providing PVS for Solaris or PowerPC on thedownload page, as we have limited funds and the vast majority of our usershave Intel Macs or Linux machines. If you do need either of these, let usknow at pvs...@csl.sri.com. We will be keeping earlier versionsavailable for the foreseeable future.
The pvs shell script has been modified to support SBCL Common Lisp.In addition, the load and eval capabilities have been simplified, where-l and -e are for Emacs files and expressions, and -Land -E are for Common Lisp files. There was an earlier -Lflag, but it loaded the file before PVS initialization, which ismore difficult to use.
PVSio now starts up without the need for loading extra library files. Thesematic attachments are pre-installed, and the supporting theories are inthe prelude. For more details on how to use PVSio, see the manual indoc/PVSio-2.d.pdf, (but ignore the installation instructions).
The NASA Manip and Field packages have similarly been integrated, andimproved by their authors. The Manip package provides many features,including Emacs extensions, many new proof strategies, and a patternmatching facility that allows reference to subterms during proof. Formore details, see doc/manip-guide.pdf (but ignore the installinstructions).
Csar Muoz has also provided his ProofLite extension as part of PVS.This allows proofs to be included directly in PVS specifications and runfrom them, allowing for a literate programming style of specification.See doc/ProofLite-4.2.pdf for details.
In the new treatment, theory declarations are simply expanded in place,with the theory declaration id prepended to the included theorydeclarations. This solves the problem with declaration references, butintroduces new issues. First, since the expanded theory declaration mayitself have theory declarations, names have been extended to include anynumber of periods, e.g., th1.th2.th3.d. In general, these are onlyneeded to disambiguate, and even then a suffix of the full name usuallysuffices.
A new Judgement form is available. This is still in the experimentalstage, but we welcome any feedback. The judgement has the form of asubtype judgement, but with a preceding FORALL that gives the typesof the variables, as well as making the parsing unambiguous. Within theforall, any expression is allowed. For example,
There are improvements to the yices and yices-with-rewritesrules. Note that to use these commands you must install Yices fromyices.csl.sri.com, and make certain the directory containing theyices executable is in your PATH environment variable beforeinvoking PVS.
A simple Emacs speedbar extension is now available. This makes browsinglibraries easier, as it lists all directories on thePVS_LIBRARY_PATH as well as the built-in libraries in thePVS lib subdirectory. This is invoked with M-xpvs-speedbar-browser, and clicking on a given library shows thespecification files within; clicking on one of them brings it up in anEmacs buffer. In the future we plan to include declaration lists withinthe speedbar display.
Most of the other incompatibilities are more obvious, and the proofs areeasily repaired. If you have difficulties understanding why a proof hasfailed, or want help fixing it, send it to PVS bugspv...@csl.sri.com.
