Drawing simple curves
show user profile  smallbear
I can't seem to draw a curve where I want it.

I've been going through the Lynda Essentials course (highly recommended) and while I understand most of Max's quirks, I still can't draw a line from one point to another.

I am trying to create plumbing outside a building. I've tried the various free scripts and they don't work.

So I'm trying to use NURBS... or lines with sweeping, and it works sometimes but not others.

I've drawn a main vertical pipe - no problems. But for the life of me I can't get horizontal secondary pipes to sweep off it. I just can't draw a line that attaches to the pipe. They always start somewhere in space. Usually miles behind where I am. If I use constrain they'll fly off in a constrained direction. If I use snaps they'll pretend to snap to the pipe in front of me, all the while sneakily snapping behind, again.. to the wall or some distant object.

Oh, and I've tried drawing on a plane and using orthogonal view to no avail. And I've been all over the web looking for tutorials and scripts.

Please help.

not a good recommendation for lynda essentials really if this is causing problems

only create lines in orthographic with the exception of if you need a line on an already existing surface in which case put autogrid on- under the menu title 'object type' in the spline rollout
either way you'll have to move the spline into place after creation

and i'm not sure by the description but i think you'll need to do branching pipes seperately

I did finally figure it out> Patch grids. Max will let me draw on them. It works just like a plane in sketchup.

In future I might try creating prefab pipe segments and snapping end-to-end.

Script pimping...

miauu's Polyline

Joker Martini's Pipe Gen

For curves I always use the Arc and snap to existing lines verts then attach and weld, then convert to beziers or whatever, max splines are funky at the best of times.

If you use Auto Grid when creating splines on a plane in ortho you shouldn't have any issues, sounds like you may have axis constraint or snaps active.

When you make a spline right click and activate "Show Vertex Ticks" is may give an indication where youe snaps are aiming.

I still use this to flatten out any stray verts...


Can be done manually, but the script is quicker.

edit: cross posted, seems like you've got it, check out Joker Martini's Pipe Gen, may save you some time.

If your making prefabs use this....

Thanks, those resources were very helpful. I'm still adjusting to the context-sensitivity of max.

I was trying to use autogrid in perspective and it just drew a single cell at a tangent to the pipe and has no affect on the spline, also the constraints had no affect on the curve.
Will try in orthographic.

Also I was using axis constraints originally then thought that by hiding the axis toolbar I'd turned it off. Is it possible it was working in the background? And if so - how do I turn it off? Activating it doesn't allow me to unselect, only to change the constraints.
