Tutorial series: Sketching fundamentals
What you'll learn
The ability to create sketches that can snap to existing geometry is a powerful tool to execute models precisely. Check out this water bottle cap example achieved by using real-time feature adjustments in design history.

Shapr can also create sketches that intersect with geometry. Let's create our geometry. I go to a top view and Sketch, Circle. I create a circle with a radius of 30 millimeters. So 60 is the diameter. Then I zoom out a little bit and exit the sketch. The profile.
00:29
of the sketch, I extrude up by 30 millimeters. And then I would like to core this out. I select the top face, go to Shell and shell this by 5 millimeters. Think about this as a small container. And now we would like to create a lid that fits perfectly on and into it. Here again, I go to the front view. So the grid is nicely...
00:58
aligned with my view and perfectly goes through the body. I go to Sketch, rotate my view. And there you see again, the snapping points where we have hard edges of my geometry. With the line command, I can now draw a line from point to point. Press Escape. Do the same here too. Basically what this did,
01:26
was I created a line and glued it onto these points where it intersects with the geometry. Let's quickly continue drawing our rest of the sketch. I go horizontal, I find this endpoint and I go down, look at these beautiful guidelines and I draw up and escape. And then here I draw a line up 15 millimeters straight up over.
01:57
and down and escape and escape. To make sure everything is horizontal, vertically aligned, double click a sketch element that selects an old sketch elements and hit horizontal vertical. Beautiful. So let's exit the sketch. We know the shelling was done by 5 millimeters. Let's go to the history, use the shell command. Let's set this to 2.
02:25
and press Enter. Look at this, you see the sketch is updated. So this means if I now go to the sketch back and I create a centerline right at the middle, that goes straight up and is glued to midpoint to midpoint. I now have half of a profile. I select half of the sketch profile, then
02:52
a Revolve body axis and go to Revolve. And for visibility purpose, I just only revolve, in this case, minus 150 millimeters. I will round this corner a little bit. Then I will select this body, click on isolate. I can select these three flat faces, do a shelling.
03:22
by two millimeters, exit the isolation mode. And then again, when I go to the first shell command for the vessel, and I change here the dimension again, back to five millimeters, you will see how everything automatically updates. A nice example of such a showcase is for example, the cap for...
03:51
a water bottle like I have here. If I go to the front view, there you can see how I created this initial sketch, perfectly fitting to the initial cap. And then I built the lid that actually went over it. If I go to the history, I'm actually using Rotate to Move command. I can right click and suppress it. So you see actually,
04:20
where the original stage was. Go back to the front view and then turn on section view. So we can look right into your design, like a section cut. And there you can see not perfectly how the ability to create sketches that can snap to existing geometry is such a powerful tool. So you have all the control to do a really nice precision modeling.
04:50
I will go back, right click and say, unsurpress. So one can see this rotatable part actually rotated away.
About the instructor
Claas Kuhnen is a German 3D designer known for his strong interdisciplinary
background in product, space, and animation design. He holds an undergraduate
degree in Color Design for Interior and Product Design from the University
of Applied Science and Art in Hildesheim, Germany. He further pursued
his education and obtained a Masters in Fine Arts in 3D Studio Art
with a focus on Jewelry Design and 3D Animation from Bowling Green
State University.
As a designer, Claas Kuhnen is particularly interested in design-informed
solutions and exploring the relationship between consumerism, products,
and their impact on society. He engages in a wide range of projects,
including furniture design, interior and exhibit design, consumer
product design, and medical product design.
In his research and studio practice, Claas Kuhnen delves into the
application of a modern multi-application and interdisciplinary workflow.
His areas of investigation encompass parametric, generative, and
subdivision surface modeling, as well as AR (Augmented Reality),
VR (Virtual Reality), photogrammetry, and AI-powered tools. He collaborates
with various national and international universities and companies
on research and design projects, contributing his expertise and exploring
innovative approaches.
Claas Kuhnen's design projects span diverse domains. For instance,
he has designed exhibit artifacts for The Henry Ford Museum, developed
medical devices for the Department of Pharmacy Practice, and undertaken
interior design projects that serve the community. His work showcases
a keen understanding of the intersections between design, technology,
and societal impact.
In addition to his design practice, Claas Kuhnen is actively involved
in teaching and sharing his knowledge with students. His classroom
experience is strongly influenced by his diverse research background,
