The sketch in IRONCAD

Answer: A Sketch in IRONCAD is a 2D sketch used to create 3D shapes. However, you do not need to define constraints or locks to work further.In IRONCAD , you can create and modify 3D models directly without first "unlocking" or "fully defining" the sketch. This means faster flow, fewer error messages and much more freedom.

Answer: No, in IRONCAD constraints are completely optional. You can draw freely, build in 3D and only add parameters when you actually need them. In IRONCAD , you can quickly generate ideas, test shapes and adjust in real time - without the system stopping you.

Answer: Traditional CAD systems build models using strict parametric modeling, where every change is governed by mathematical relationships.
IRONCAD , on the other hand, uses a hybrid approach - you can work flexibly, parametrically, and directly, depending on what's best for the project.
This means you get parametric control when you want it - but can work quickly and intuitively when you just want to create.

Answer: You start with your 2D sketch and then choose one of the four basic tools:

• Extrude - create a solid by pushing out the profile.

• Spin - rotate a 2D profile around an axis, ideal for cylindrical details.
• Sweep - sweep a profile along a path, e.g. for pipes and cables.
• Loft - create complex transitions between multiple profiles.

These tools work instantly - you don't need to have a fully defined sketch to proceed.

Answer: IRONCAD's unique drag-and-drop catalog system allows you to use ready-made sketch-based objects and customize them as needed.
For example, you can drag in a standard profile from the catalog, adjust it with handles, and drag your variant back to the catalog for reuse.
This provides a very efficient and scalable way of working - something that is lacking in many traditional CAD programs.

Answer: Smart Dimensions allows you to choose when dimensions are fixed or dynamic, and the combination of handles (Sizebox) and dimensions gives you full precision yet flexibility. So you can achieve the same accuracy as in e.g. SolidWorks Sketch - but with much less frustration.

Answer: Yes, if you want to. IRONCAD allows you to build directly in 3D with ready-made shapes from the catalogs, but for detailed geometries, special profiles or advanced shapes, the sketch is an invaluable tool. The best part is that you choose when to use it - the system never forces you.

Answer: Because IRONCAD combines flexible, direct modeling and parametric tools in the same environment. You don't have to switch modes or think about relational errors. The sketch is just part of the process - not an obstacle. As a result, many users who have switched from traditional CAD systems find they can work up to twice as fast in IRONCAD.

Answer: Absolutely! IRONCAD allows you to add dimensions, constraints and relationships after the fact. You can start with a free sketch to quickly build 3D shapes and then add parameterization when the design requires precision. This is perfect for iterations and product variants.

Answer: When you modify a Sketch, you can use handles directly in the 3D view. This allows you to change lines, angles and dimensions without opening the sketch itself. The combination of Sketch + handles + Smart Dimensions provides maximum flexibility and control in the same workflow.

Answer: Yes! IRONCAD's catalog system allows you to save your Sketches and Sketch-based models for future projects. You can drag a modified profile into the scene, quickly adjust it, and then drag it back into the catalog - perfect for recurring components or standardized details.

Answer: Many users who have switched from other systems find that IRONCAD's Sketch system is much faster for concept design and prototyping. You are free from constraints and can work directly with the model, which significantly reduces iteration time and allows more room for creativity.

Answer: Yes. Sketch is fundamental to several Modification Features like Rib and Emboss. You simply draw 2D lines and IRONCAD generates the shape directly in 3D with full control, without having to worry about constraints or complicated parameters.

• Use webinars and instructional videos from Solidmakarna.

• Take advantage of the catalog system for reusable Sketches.
• Combine free modeling with Smart Dimensions.
• Parameterize only when necessary.
• Use handles (Sizebox) for quick changes directly in the 3D view.

Answer: Yes! IRONCAD is intuitive even for new users. You can start by creating simple 2D profiles, extruding and rotating them, and then gradually introduce Shape Features, Smart Dimensions and parameters. Webinars and support blog provide step-by-step guides.

Answer: For complex geometries, lofty shapes, swept profiles, and detailed ribs, Sketch is often the fastest and most accurate way to define the basic shape. Although IRONCAD allows direct modeling without Sketch, Sketch provides full precision and reusability.
