Does anyone know how to duplicate an object (many multiples - using a linear array type operation) along a surface?

Its a curved surface and needs to follow a specific path with an equal distance between each object.

I'm using SharkCAD.

I attached a screenshot of what I need help with and also the .slt file.

Thanks in advance.

Does 'path duplicate' pick up the curve on the surface? Not sure if it only works with straight lines or not.

**Edit**It does work, just tried it. Go MODIFY - ADVANCED TRANSFORM - PATH DUPLICATE. The last action '2 points for alignment axis, is basically start and end of the line you are going down.**

Just use the linear duplicate command since the surface is pretty much extruded straight. See example using -1" spacing with 20 duplicates.

THank you, I will try that also; what I'm trying to duplicate is a tiny rivet head along the Z axis (well along the curve in a general "Z-ish" direction).

I tried Path Duplicate and it works except I can't get the Rivet head to follow the contour. I'm not sure how to make it look like the rivets are actually installed in the curved surface. Its just for a rendering so doesn't need to be perfect.

The only other way I can think of is use Points on a Curve to make even-distance points and then manually place and rotate each.. But i can't help thinking there's an easier way.

you need to use the pattern command with along path. This is in the 3D tools.

I take that back. that only works for a hole or a feature on the part that you want to duplicate. You are in the right track with path duplicate using the option tool to use the normal of the curve. It is best you place the rivet on the xy plane and follow the prompts. It is a bit tricky. Just don't put the first rivet on the curve but rather the xy plane.

Suppose you can always use a sphere send the sphere down the curve, with path duplicate, so it's got a little sticking above the surface. Then use your surface to split the sphere solids, leaving you with a rivet head.

Hey! You did it! Thanks! Exactly what I was looking for. :)

Thank you! That's a really interesting AND workable solution. In the future it would be nice if there was a 3D Array tool that could be used for a variety of rather complex patterns. It could duplicate an object in all directions in a preset or numerically-driven manual input. Maybe its in the works -- or already exists and I just dont use it?

I've noticed with some of the pattern tools etc that the work plane affects the end result. So when you look at the work plane, you have the two big arrow outlines and the thin little arrow is what seems to be used in some instances.

Good point -– it takes some experimenting. I was able to get it this time but it was by adjusting where I was clicking on my object as its reference point, and also trying various "start" and "end" points. Each yielded a rather different result..

Hello,

Maybe it will help you.

be careful, do not forget the hidden function ..... lol ?

option (Alt) when last entered with the mouse to choose the support surface.

Thank you.
Yes there are many things hidden in this software.
Unfortunately, the hidden options disappear from the menus with the years.

As I have already said often, the manual instructions must be corrected and above all, be made more attractive.
