Question: As a beginner, I find it difficult to see and understand the difference between a Part a Feature. Does it really matter which is which?
A block that you release from a catalog creates both things, right?
Answer: Yes, it can be tricky before you see and understand the difference. But once you get past that threshold, it's actually quite simple.
Details and their Building Blocks
One Part corresponds to a detail that has its own name, item number, color, and can carry a lot of other metadata. All this information can also be transferred and displayed in the drawing header or bill of materials (BOM) of the 2D drawing.
A Feature corresponds to a building block that is always part of a Part. It is primarily used to create a geometric shape as part of a detail, but of course it has a name and a unique color, but it can never contain metadata that is displayed on a 2D drawing.
Part consists of one or more Features.
Feature builds up a Part.
Copying Part Feature?
A very common problem that we often see in support is that a Feature has been copied Feature of a Part.
The reason is usually that the Part consists of only one Feature and therefore the edge lines for a Feature yellow) match exactly the edge line that the Part also has (blue).
The result on the screen may initially appear to be correct. The copies of the "model" you copied all appear to be in the right place. However, if you look at the history tree, you will see that there is still only one Part that it now consists of even more building blocks. The 2D drawing's parts list will not list more rows or change the number of that detail, even though you can see the new models in the views. So even though everything almost "looks right," it was not exactly what you expected to happen.
Copy Part
Select the blue part before turning on the TriBall.
The result of the copy should be a new blue part(last) in the tree.

Copy Feature
Select thefeature be copied before turning on TriBall.
The result of the copy should be a new feature placed last under the blue part in the tree.

There is also a post that explains how to split a part several parties by "splitting" features into new parties. More on that in another post.
Answer: Here we publish tips, guides, news and solutions for those who work with IRONCAD and Design Data Manager (DDM). The blog covers everything from basic functions to advanced workflows, helping you to optimize your design work. You'll find examples of smart shortcuts, practical instructions, solutions to common problems, and best practices for product design, mechanical design, and product data management.
Answer: Our guides and tips are designed for both beginners and experienced CAD users. They are aimed at designers, engineers and project managers who want to work more efficiently with IRONCAD and DDM, improve the design process, reduce mistakes and save time in product development.
Answer: We regularly publish new articles when the software is updated, when new features are introduced, or when our users ask for solutions to specific problems. The blog is therefore a reliable source for keeping up to date and getting tips that make everyday CAD work easier.
Answer: Many of our instructions and tips work in multiple versions, but we clearly indicate if an article applies to a specific version. We strive to make the content useful for older versions as well, and also provide recommendations on how to adapt workflows to the version you are using.
Answer: Absolutely! If you can't find the solution in the blog, you can contact our technical support via solidmakarna.support. Our experts will help you with everything from installation and configuration to advanced features in IRONCAD and DDM, so you can solve problems quickly and efficiently.
Answer: Yes! We appreciate suggestions from our users. If you have questions, tips or want us to address a specific issue in IRONCAD or DDM , please contact us via our contact form and we will prioritize relevant topics in future posts.
Answer: The blog contains, among other things:
Practical step-by-step guides to help you use IRONCAD and DDM more effectively.
Productivity and workflow tips for faster design and construction.
Solutions to common problems encountered by users in CAD programs.
Updates and news on new features, versions and improvements.
Best practices for data management and project organization in DDM.
Answer: All tips and guides are directly applicable in daily work. For example, you can use shortcuts and smart features in IRONCAD to speed up modeling, structure files better in Design Data Manager, or follow our step-by-step solutions for specific problems that often come up in design projects.
Answer: We strive to ensure that all guides and tips are relevant to the latest versions of IRONCAD and DDM. We also clearly mark when a post applies to an older version, so you always know if the instruction is directly applicable to your system.
Answer: Yes! Many of our users share the articles with colleagues and use them as internal training materials. The blog is a great complement to formal training and helps teams learn features faster, avoid mistakes, and standardize workflows in IRONCAD and DDM.
