How to extrude multiple sketches (circles) made using Pattern command?

ovisopa — Sat, 08 Apr 2017 12:23:00 GMT

Hello guys,

I started again to play with Fusion, I was thinking while I learn to model it's a good ideea to start modelling something that will be usefull for me, so I started to model my workshop space, right now I try to think of the best way to store the sheet of policarbonate, and fiberglass that remain after I mill from a larger sheet, every few days I also need to mill smaller parts and it's nice to have them separated by thickness, when I'm looking for a part to look exactly in that compartment.

I try to model the metal part bello, I want to cut it in half, and use each half for one shelf. So I made a 5mm circle and I tried to find a way to duplicate it 22 times, I could only find Rectangular pattern command, and made 22 copies of that circles. But now I can't extrude all at once, I can make the first one, but can't select the other. Also If I extruded the first one, others didn't extrude.

So what is the proper method to make multiple copies of one thing, spaced by let's say , 50mm ??

Best practice is to extrude one circle then pattern the body with using a rectangular pattern from the create menu.

I tried to but I got an error, I will try now to make a pattern on a different part

It worked, I think I haven't selected body, I left that option selected to face, now after I selected bodies it made the copy

Yes copying a face of a cylinder will give an error because it will leave an open body. You can use faces as long as the copies are not open, something like this will work.

I made the copy, but now after I created another copy of one body, and scale it 2x to make it thiker, rotate it and placed it above al the multiple copies, I almost made what I wanted, but noticed I made to many copies, and now I'm having trouble deleting them, and even make the top horizontal bar smaller by using Extrude command.

For the extrude problem, I selected the end of the horizontal bar , press E, and move the cursors as you can see in the picture, after pressing ok , nothing happens with the bar, it remains the same size.

And about deleting horizontal bars, I noticed I can't delete it by selecting the face, if I double click it selects all the other bars, I could only delete it if I selected all elements of a bar, the top and bottom contour, the face of that contour, and the cilindrical face, but it was a pain in the a** to select all those as also zooming seems weird sometimes, sometimes it moves very very little

So in the feature, what I should do when i want to create something that interconnects with other elements and I might need to modify them , like in this case, the horizontal bar had been place on top of the vertical bars - touching each other

I figure out, I think I couldn't extrude from that end because that was the origin of that body ? I noticed when I tried to move it that the arrows appeared in that end, so if I moved it to the right, and than extrude the other end , in worked.

It sounds like you're using the wrong workflow for a solid modeling program. It is far easier to make another sketch and extrude for the bigger diameter rods, the trick of scaling sounds like a Rhino 3d bodge. As for removing copies from the pattern, right click the pattern in the timeline and select edit then reduce the number of copies.

@ovisopa I've made a screencast to demonstrate how to make a parametric version of your grill. The files attached, import into Fusion using new design from file on the file menu. I've added names to the parameters to make it a bit more easy to edit, the spacing has to be a minus number.

Thank you Mark, thank you very much for the screencast 🙂

From the beggining to minute 1:13 I did the same, but from there on everything was way different from what I did (one reason I chose the quick and dirty way, was that I didn't cared about any tolerances, I only knew that the grill is spaced 50mm away, and has metal rods of 5 and 10mm, those things I respected, but when I placed the thicker rod above all the thinner one, I just placed it "by eye").

I noticed in your video how you create a new plane - this is one thing I didn't knew (didn't watched the tutorials about planes, only the first few tutorials) and had a lot of problems because of it, when I start a new sketch, to add new objects, sometimes I click the wall to chose the plane (when making the 220v wall mounted socket) and suddenly the active component is switched to another one, don't know why it acts like this , I installed Screencast recorder and made my first one with this problem, but from now on I will try to use more often the Offset plane

PS. I don't have any experience in other 3D programs except Sketchup 🙂 but I can say that didn't help now when I moved to serious 3D modeling , it's totally different, way different 🙂 I understand now that it will need more time to get familiar with Fusion, and than move to the CAM part - because this is why I need to learn Fusion, to be able to mill steel parts with my new Tormach 🙂

PS. to admins 🙂 I tried to edit my previeous post to add the PS above, but my screencast dissapeared from the post, and there was no screen cast option while I was editing my post... so I didn't saved it , created this new post instead.

Hello, I want to so something very similar in concept, but from my understanding pattering features bogs down performance. Now it works for single parts and small Asm's but I'm building a very large Asm ranging from 30-100k parts total then each part is used more then some so the reoccurring instincts get big fast.. We have seen performance issues with pattering features but not sketches. So is there anyway to have a extrusion grab everything from a sketch and extrude it?

Hi,

If you extrude sketch patterns you're gonna fail a lot earlier.

I have best results using faces instead of features.

One more way is to split in groups.
