PLEASE PLEASE Help! Combining / Merging Issue!

[Anonymous]

Hi, I have just joined so am a newbie in the forum.  Exploring 3D printing and need some help please. How do I create a tapered 11mm slot hole,  26mm x 11mm (slot hole top), to 11mm (hole at bottom), placed 25 x 4 times (100 holes, 4 rows or 25 holes), exactly 14mm center to center of 11mm hole, side by side along the 25 hole axis, in a 30mm thick block please?

I would actually be happy with 1 correct hole in a small block at this point, and a way to duplicate it myself.

I can create the block, with round holes, and I can create the slot shaped hole separately, but nothing I can find to try so far is allowing me to do this in a way that puts that slotted out hole in the block.  I accept I am new but I have spent so much time for a couple of weeks watching videos and reading instructions, and I am clearly missing something. PLEASE HELP...

Block link below, if I have done it correctly.

Have you tried using the Rectangular Pattern command?

First you need to make a solid hole, then you can use the Extrude|Cut tool to create the hole:

Note: Fusion 360 doesn't handle large patterns in sketches very well.  It's better to do the pattern in the solid model.
