NX improvements shown on PLM Europe 2015

PLM Europe is an annual conference, centered around Siemens PLM product line. Most of presenters are from Siemens PLM, showing the new features of the software and further development areas. There are also software partners and customers, showcasing the add-ons and examples of software use. Here I would share the things I found interesting and will give some comments regarding presented features. My overview covers mostly NX CAD. Smart innovation At the beginning, the tendencies in innovative technologies were presented, and Siemens PLM portfolio was shown to support the needs of these technologies and of today’s devices. This was mainly related to three topics: Digitization of early stages of product development System-driven product development So-called “Digital twin”, which is mainly about production simulation in Technomatix One more …

Replace components in a machined assembly

Overview Some time before, I promised to look at the special techniques which help to replace components in assemblies with machining features applied to them. In this article I’ll describe them in detail. In complex products, machining after assembly is a typical scenario. On the other hand, it is often required to replace components in a CAD assembly. It is done in at least two major cases: A design change is required, which involves replacing components with their updated versions A new design is being created based on the old one, which requires replacing a number of components with different ones. Therefore, it is often needed to replace components which have modeling features applied to them at the assembly level. In NX it is not very …

Free NX tutorials, part 1: The place of free tutorials in the learning process

I am often asked, especially after starting CADroad, if there are any free tutorials for NX. My answer is: “Yes there are, but if you are a new user, I believe they should be used with care”. I have taught NX for several years and sometimes I give links to these materials to my trainees to follow up the training. But I tell that they should understand their limitations before starting to using them. Here I explain what kind of tutorials are available for NX and what is the place of free tutorials in the learning process. In the next parts, the lists tutorials would be provided. Official training centers When someone ask me: “How do I study NX?”, my usual answer is to order …

Ideal PLM Technology Day Russia 2015, conference notes

Technology Day is an annual conference organized by the Siemens PLM partner ‘IDEAL PLM CIS’. Each year it gathers CAx and PLM experts from Russia and CIS. The conference had two main sections, one dedicated to NX and one to Teamcenter. Here I show what I have found interesting. Metrovagonmash The presentations were started with “Metrovagonmash”, a Russian designer and manufacturer of underground railway trains. First, the history of NX use was shown. The first models were developed in early nineties. At that time the 3D geometries were done in relatively low detail. Gradually, the level of detail was increasing, and project was run for transferring 2D drawings into 3D. Over 10k documents were processed resulting in around 11k unique 3D models of components. Currently, NX assemblies form …

Improve drafting, part 3: Reuse drawing objects

This entry is part 3 of 3 in the series Improve drafting in NX CAD

This entry is part 3 of 3 in the series Improve drafting in NX CADI personally find the name “Custom drafting symbols” a little misleading. I think it refers to a much wider variety of objects than actual symbols. Personally, I prefer defining it as “reuse library in drafting”, since you can define almost every kind of drafting object. Based on my support cases I have noticed that users are not familiar with full scope of that powerful tool. Scope of drafting symbols In brief, the following capabilities are available: Reuse of sketches, including addition of fillings, crosshatches, dimensions Reuse of tables and annotations Possibility to define existing DXF/DWG as symbol Creation of drop-down lists with value, meaning that you select or enter value when …

Become a CAD user in 30 minutes with Free CAD

CAD software is simple and does not require much effort to start with basic modeling. In this article I will explain the basic principles of CAD modeling and will make a simple model in freeware CAD (called FreeCAD).   About free CAD software. Good news is that these days you don’t need buying CAD software license to start working with it. Simple CAD freeware would suite basic tasks and can help you getting familiar with basic modeling techniques. As soon as you feel that you need something more advanced, you can try some mid-market commercial packages. Most of them have a trial period and, if you are already a confident CAD user, this period is enough for deciding whether the software suits you. Each software has its …

How to model machining after assembly in NX

Introduction As I promised you before, my new article looks into tools that NX provides for modeling of machining after assembly. Thanks to the unified PRT file format, in NX there’s almost no difference between modeling at the part level and assembly level. The only difference is that at the part level we can directly modify bodies, while at the assembly level there’s no direct access to the bodies of components, and it must be provided first. In NX there are three ways to alter component and the assembly level, based on the following techniques: Body promotion Assembly Cut WAVE copy Each of these techniques has its own advantages, and also its own characteristics, which must be taken into account to avoid errors in the …

Improve drafting in NX CAD, part 2: responsive drawings

This entry is part 2 of 3 in the series Improve drafting in NX CAD

This entry is part 2 of 3 in the series Improve drafting in NX CADThis NX drafting-related tutorial shows you how to improve the of reusability of the drawings. It means that minimum efforts are required after a model is updated. If you take your time to make a parametric model for reuse, you also should consider spending some time for making responsive drawing. NX drafting tips and tricks. The recommendations I show here do not remove the necessity to check the drawing after an update is done. However, they can guarantee that dimensions would be always be correct and overall minimum adjustment is needed. 1. Position the views in the responsive manner. In case your model changes one of the main dimensions, your views could intersect with each other …

Improve drafting in NX CAD, part 1 introduction

This entry is part 1 of 3 in the series Improve drafting in NX CAD

This entry is part 1 of 3 in the series Improve drafting in NX CADThis article series describes various ways for improving your performance in NX drafting. Part 1 gives an overview of the functions, further posts will describe these functions in detail. Introduction to drafting efficiency. While the basics of the drafting application can be understood quite intuitively, there are some additional tools which can improve your productivity when creating a drawing. There are a tools which can standardize some common drafting procedures, and tools for making the drawing updatable (meaning minimum changes are needed when model changes). Reuse drafting objects. The reuse of components and features has a proven positive effect on modeling of parts and assemblies. In a similar way, this can be utilized in …
