MORPH: Tube extrude along a 3d path - profile centre?

Anonymous — Wed, 24 May 2023 17:30:56 GMT

Hi,

If I want to use the Tube Extrude tool along a 3d path I leftclick on a profile and this point becomes the centre of extrusion. It is not too precise (i.e. if I want to select exactly a centre of a cicrcle). Is it possible to have more control over it?

I've found getting Morph hotspots to show in 3D and be usable a little tricky.

For example, if you are extruding a circle, made with the Morph tool in 3D... if you shift-click the circle to select the Morph, no hotspots show up for me on Mac when moving my mouse around the surface.

But, if I move (not click) my mouse over the edge of the circle/profile so that I see the Mercedes cursor .. then a hotstpot shows up at the center and and division marks along the edge. I can then snap (checkmark) click on the center and extrude from the exact center with the tube pet palette option.

You can also draw as many temporary guidelines in 3D as you might need to find a point - for example, create two guidelines that allow you to snap on their intersection. (Create Guideline Segment command ... probably assigned to a shortcut key - mine is shift-`)

Tube tool is a bit strange, as a whole morph. I don't want to complain too much, but it do less than 3d apps could do years ago.

To pick a precise point you need to activate the tube tool and pick again a point on a starting surface (like 0 extrusion).

But a real shame is that it cannot just extrude along the 3d path - why?

Morph tube is very powerful. In the youtube channel there are some videos that explain how to do.

For example, this is a very simple profile extrude to a 3d path. Is very, very easy.

Thank you all for your kind replies.

@Karl

Hi Karl, it’s me Bartek from Artlantis Forum (i.e. we were trying to figure out Maxwell Render Core licensing about a month ago). I agree with you: Morph surface behaves similar to slabs in 3d (it has only external boundaries and hotspots, no virtual ones: center, mid points etc). The way to get around it is to draw additional point (in 2d) before extrusion.
I have to say that I love this Morph Tool. ArchiCAD 16 is a big step forward.

Cheers

Bartek

Come on in theory it is powerfull but in practical use ? Just try to draw a railing - first you have to draw a 3D polyline, than draw again a 3D tube along this polyline (and 3D window is so lame in archicad) - even worse when you need to hide or cut bits of model (3D cutaway nightmare). Is it really that nice? Who needs this bulge function - just give us the most simple 3d modeling options like extrude along path, rail, split etc.

And the best one - can't edit morphs or even copy them in section/elevation - why?

When you practice a bit you realize the powerful of the morph tool. I have made some practices,
archicad-talk.graphisoft.com/viewtopic.php?t=40191 and I think that morph its very easy to use and very intuitive. If you have some skill with other programs like C4D you find some tool very similar of course limited but I think that its a very good start point.
Morph has some tricky specially with the tube tool! Of course you can extrude along a 3d path (as the example a post before) and you can split too with the "axe".
With archisuite you can copy morph in section and elevation, and with the cheap "simple add ons" too.
I have made some videos and when I receive my Archicad I will post some of then explain how to do some objects with morph tool...

Ok so what I am missing with that extrude along 3D path. I draw a 3D path with the morph tool, than draw a profile and what next?

Copy in section with add-ons - still no sense for me, or maybe they want us to buy them.

One more horrible thing is the drawing in 3D with no possibility to lock to xyz axis - generally archicad 3d environment is so obsolete. Take any competitor and see what they got.

My point is that much better is to model in sketchup, import and convert to morph than do modelling in archicad as the 3D windows is clumsy and slow. Every archicad user needs to know tons of work-arounds to do simple stuff. This nice piece of software is suffering from bad UI design, its like it is developed by people that are not working on it.

Please hire a interface designer - make v17 a modern tool. It's not far away - just get some architects to help you.

Do you have your editing plane turned on?
It can be set at any position either horizontal, vertical or at any specified angle.
Then your editing is constrained to this plane.

I know editing planes, but still no easy way to just lock the axis (like in sketchup or rhino)

I know that you guys are amazed by this morph tool, but damn - archicad got even more complicated. We have to learn tons of new tricks to draw simple stuff - and its not even in XXI century.

We do have generative components, visual script editors, nurbs, etc. existing somewhere in modrn architecture world. Not here.

And in archicad I can't even design my own light, or window (not talking about dumb objects that are not parametric) without programing skills.

You can use other software programs, try many programs and when you find one that like you, buy it... I tried some software before archicad: ADT, Allplan, Revit... and for me Archicad its the best (for now).
Made a tool in gdl for generative components is very easy... I made two dragon and medusa

So if I can do (im architect no programer) I think that everyone can do, and of course if GS want they can do it a lot ot better

I agree that it isn't perfect tool, but creating 3d railing is as ease as never before.

My point is that we all invested loads of time/money in this software hoping that it will do the job and each next version would be better. In my opinion it is worse and worse - somebody has to tell that. Archicad has a great potential, but for me it is all spoiled by very stupid bugs, constrained tools (with no logical reason) and uber complicated program structure.

For me v17 should focus just on simplicity, ui and logical tools. I don't want to learn another tons of work-arounds for the simplest things. Honestly please hire some architects to help you !

BTW I have managed to extrude a profile along a 3d polyline (morph polyline - of course normal polyline can't do 3d) - guess what it has to be a closed polyline - so if you want to draw a railing or anything that needs to be extruded along open polyline - forget it. Thats what I am talking about - no logic in that tools.

stayrudee,

You can extrude a profile along an open "3D Polyline".

Ok so what I am missing here - when it is closed I pick the profile, than pet pallet tube and pick a polyline with space bar. It is not working on open polylines for me - do you draw that manually ? I am talking about extruding a profile along a path as it is in all other 3d apps.

AFAIK it does not work like in SketchUp which is the way you are describing.

In this case you have to follow the 3DPoly using your mouse not use the magic wand which is the same as the original "follow me" in SketchUp.

Which is "you have to draw that twice 😉" But it does work when the 3d poly is closed.

I'm having some issues with Morphing railings and the quoted statement above sounds promising, however never have drawn a 3d polyline, and don't see polyline available when I'm in 3d, searched AC help and archicad wiki and can't seem to find how it works.
Just a bit of direction here would be nice.
Thanks

Select the Morph Tool.
Click on the 3DPoly button.
