I want to extrude like this.
Any method is OK.
I challenged.
The outside was made by extruding a poly group.
There is a topology on the outside.
But,
This method cannot be used for such internal parts.
Please help me.
Hello @beginner
Just to be clear, I think Iâm looking at a piece of fabric with a raised piping or stitching along the side. Is this correct?
What do you mean by âinternal partsâ? Do you mean the recessed area in between the two âpipesâ? Polygroups can be extruded either above or below a target surface (positive or negative extrusion).
Many artists might chose to sculpt in this sort of detail at high resolution, using Lazy Mouse as an aid.
Panel loops are also a popular way to establish clothing seams and details based on polygroups.

Thatâs right.
It is piping.

Inside piping.

The result was not ideal.

The topology is different and Panel loops could not be used.
It was usable on the outside.
However
The result was not ideal.
I think I understand the problem. The issue here is that your mesh topology does not support the sort of extrusions you want to make with low poly modeling.
So you must either re-draw your topology in the form you require, or you must sculpt in the detail at high resolution in a way that is not dependent on the topology being exactly perfect.
Unfortunately, both of these subjects are very large and complicated in themselves, and I will not be able to instruct you on a single ârightâ way to do this within the confines of this thread, especially if there might be a language barrier.
Retopologizing your mesh in the exact way you need to be able to extrude your geometry in the exact way that you want to do it, will require you to understand the various ways there are to draw topology in ZBrush. Study ZRemesher, and the Topology Brush.
If attempting to sculpt the detail in, be aware there are many ways to create custom brushes in Zbrush. You can control the shape that they make by assigning a custom alpha to the brush:
Study the Lazy Mouse and Stroke controls for how to get the smoothest strokes. Increase Lazy Radius, decrease Lazy Step, and activate Sculptris Pro mode to be able to sculpt smooth high quality detail into the mesh regardless of the meshâs resolution.
You could also draw the shapes out as tubes with a curve tube snap brush and then fuse it to the surface. You could create the stroke as a curve IM brush, and then fuse it to the surface. You could paint the lines as polypaint at high resolution, convert them to masking with âMask By Colorâ, and use a Tool> Deformation> Inflate operation on them. There are so many different ways to do this I lose count, but they will all require a degree of skill with the program.
Good luck!

Thank you for your reply.
I have tried all the methods that you have taught me.
The piping is round.
zremesher(extrude)
It is a square.
Ideal.
For that reason,
It might be better to do a retopology and then a zremesher (extrude)?
