didn't know that it was such an option - selecting body - planar
i was doing as usual, selecting edges !
thanks !

need some help with developing a function for move script
move arc -> draw helpers(points) on missing bbox frame (wanna use for arc -> draw points/aids for corners)

Hi Tudor,

re:

I'll need a lot more detailed explanation of what you're trying to do to be able to understand it and help.

thinking more idea won't work
will be good for next version - where will be point selection in scripting
idea is simple
whenever i've determined there's an arc or simple bended curve draw aids on corners as shown - pivot points on missing corners

extrude problems
i know there are ways around it, wanna show current
cylinder, cutted with a plane
selecting cutted smaller piece top face - extrude -> no problems, with cutted in between, extrude -> slows down and shows artifacts, any scale

Sorry I don't understand this at all. Are you looking for some way to make a point picker snap to those points you show?

What command is the point picker running in? Are you talking about a pointpicker in a new command you want to write or in an existing command?

Hi Tudor,

re:

Can you please post a .3dm model file with the cut cylinder in it that you are seeing the artifacts with?

extrude

snap yes
there's no easy easy other then build construction lines
move/rotate from corner point,scale/copy .. etc -> mostly for 3d view

another idea with arcs
polyline round corners -> add a snap point of last distance(red) on new drawn contruction line or holding shift snap line -> manual fillet or draw arcs
other words -> distance from a to b to project on b to c if it's a contruction line

Hi Tudor,

re:
> extrude

Thanks for posting the file. What piece should I select and extrude to see the artifacts that you were asking about?

No easy way to do what exactly? I'm sorry but I'm not getting enough information from you to be able to understand what you're asking about here.

another future that will benefit
offset extend to cap surface

external link, out of space https://www.sendspace.com/file/zara2u
any red/orange selection

i'll post geometry later where i see benefits
as more detailed explanation

Thanks, I can repeat the extrude artifacts over here now. But they only seem to happen when the extrusion is a very small distance away. Once you move more than about 1 unit the artifacts disappear. Is it the same over there?

I think the artifacts are related to difficulty in doing boolean calculations on small slivery objects.

I might be able to improve this, I'll put it on my list of things to investigate. Thanks for sending it in.

using rotate is possible to align parallel to one edge with one construction line, or ways todo it easier

Hi Tudor, you can capture a direction with a construction line and relocate it to the rotation center, then use snaps.

Here's a demonstration:

thanks !

using this script
moi.geometryDatabase.deselectAll();
var a = moi.command.lastCommandRevisionStart;
var b = moi.command.lastCommandRevisionEnd;
var objects = moi.geometryDatabase.getObjects();
for ( var i = 0; i < objects.length; ++i ) {
var obj = objects.item(i);
if ( obj.databaseRevision> a && obj.databaseRevision <= b ) obj.selected = true; }

akka: LastCreated Object/objects -> usefull to control arrays or booleans/new geometry/curves so on
& i have some troubles
1. If I'll move an object, scale, rotate - it will count as last object, not new one created(let's say I've created a circle before - and script will record last object as LastCreated)
2. after creation if i'll cancel next operation, it wount count as last created (ex: created circle, try to move, didn't like, cancel - Last created won't count any more, history gone)
good addition will be -> undo saves last created tree* -> after 10 creation & 6 undos, will selet '4th created
as i see this should be ~ history records on new created objects, correct me if it's not designed application
