Re: Screw Thread

Hi meme2704
I figured that approach was probably best, but I don't know a simple way to do it!
Can you explain your process?

Screw Thread

Hi all. I'm having difficulty with screw threads for fast prototyping suing an FDM 3D printer. I need to build a part with an 18mm (¾") BSPP External Thread. The base of the part is as shown in the attachment. I've checked out the "Thread for Screw Tutorial" page, and The Macro Bolts ...

SOLVED: Why can't I pad this?

Hi all I have a sketch (attached) with 10 components which according to Sketcher is fully constrained - the 10 components are linked by a separate backbone in another material. But when I go to pad, I only see one of the components - and padding doesn't seem to do anything to that! I can go into the...

Intersecting pockets

Hi I'm trying to create a right-angle water feed attachment for 3D prototype printing; I've created the housing shape, and added the two sketches for the actual passage through it. (attached) But to simply pocket the two sketches by the right amount will result in the corner part of the housing havi...

Re: Can't create pocket

Thanks everyone, I didn't realise that the version on the Linux-Mint repository was so out of date. I added the up to date PPAs, but there were too many unmet dependencies, so I installed the AppImage. I tried all the suggestions; the one that finally worked was to entirely remove the block at the b...

Can't create pocket

Hi all and thanks in advance. I can't seem to create a pocket in my model. I created the basic model from an imported dxf file, which I then closed and padded. I've tried several iterations of the next step, which is a pocket to remove a section of the pad, but to no avail. I can see the sketch, and...

Re: Asymmetric tapered hole

microelly2, thanks for the tip. meme2704, that's almost it, thank you. The circle at the bottom of the hole is centred in the hole, rather than off-set, though, and the hole is perpendicular to a face that is at 45 degrees to the main axes of the drawing - sorry if I misled you in that regard. Harry...

Asymmetric tapered hole

Hi I have a real challenge: I cam't even work out where to start. I have a flat surface which is at 45 degrees to the Y and X axes. In that surface I need to form a tapered hole, but one that it not circular. A 2D drawing of the hole is attached. I presume I can create the item, and position/align i...
