AutoCAD Visual LISP / AutoLISP :: No Param On Closest Point?
Jan 4, 2012Find attached 2 files , a DWG and a LISP
The dwg show a LWpoly, and 3d-poly.
I try to get the param at the closest point, from each vertex at the LW, at the 3d-poly
But as you will see, for some closests point at the 3d-poly there, is no Param
Check at

3ds Max Animation :: Closest Point On Plane
Aug 17, 2011I need this information for an animation rig.
Let's say I have an arbitrarily oriented plane, and somewhere above that plane, I have placed an object. Now, I want to calculate the closest point on that plane to the position of the object, and constrain a third object to that calculated position.
If I move the object above the plane around, the object on the plane should always move to a position where it is as close to the first object as possible without leaving the plane. Is there any reasonable way to do this with on-board 3ds 2012 features?
AutoCAD .NET :: How To Get Centroid Point From Region
Oct 16, 2011I need to find center of Region (refer to as Centroid in MassProperties of acad, also known as Centre of gravity if 'element' mass is unique). After few days of googling, searchin i this forum... I still can not figure it out how to get centroid point from Region in VB.NET. For Solid3D is easy while it exposes this property, but Region does not reveal any properties except Area.

AutoCAD 2010 :: How To Find The Tangent Point Of 2 Circles
Dec 12, 2012I want to find the tangent intersection point between 2 circles within certain conditions.
Circle 1 is r: 30 m and is fixed.
Circle 2 is r: 20 m and its position is inside circle 1.
Circle 2 can be moved in a given angle.
The question is: what distance should circle 2 move, to become tangent with circle 1.

Nov 15, 2012I need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.

AutoCad :: Select Line Start / End Point That Is Known Distance From OSnap Point?
Jun 9, 2011I'm trying to draw a plan of my house in Autocad 2009 but I seem to be endlessly using trim and extend because I can't easily select the points that I want with osnap. Eg. imagine I have a box, and I want to start drawing another box inside it that has each side as 10 units smaller than the corresponding side on the outer box.
Step 1 - I draw a small line from the top left corner of the big box using the endpoint snap, typing in "5" for the length.
Step 2 - I then do the same at right angles to the first line to get me to the starting point of the inner box. This always leaves me with 2 small lines to remember to delete.
Step 3 - Then in order to draw the top line of the inner box I end up drawing to a random length because I can't say "draw until 5 units away from the right hand side of the big box", then I end up trimming it later once I've repeated steps 1,2 and 3 for the next side of the inner box.
I know in my example above I could have scaled the box down or something but that's not what I'm getting at. I really want a way of selecting line start and end points that are a known position away from an existing point.
AutoCAD Civil 3D :: Import Point Data For Each Point Includes Hyperlink
Jan 17, 2013I have a database of points I am trying to import, and the point data for each point includes a hyperlink. I've created a set of custom User-Defined Property Classifications for all the data types in the point database, and I've created a point file format to use to import the points.
It's a database of existing curb ramps, the data includes things like widths, slopes, some text, and a hyperlink to the Google Streetview at each ramp. I've created a custom point label that will show the data I need to see at each ramp.
All goes great except that the import fails because of the hyperlinks. I've tested it by removing the hyperlinks from a small test portion of the data set, and the test points are then successfully imported. I suppose I can delete the hyperlinks from the entire database, but if there is a way to include the hyperlinks in the point import I would prefer that.

View 9 Replies View RelatedAutoCAD 2010 :: Matching Up Point Clouds Using Alignment Tool / Smooth Object From Point Cloud
May 30, 2012how to match up certain points. I have imported 2 point clouds and have tried to use the 'align' tool to specify three points from the source object (cloud) and three points from the destination object (cloud). When doing this, it does not properly align them. The point cloud makes it difficult to select the exact point I would like to align, since there may not be a point at that exact location, but close to it. Does AutoCAD require the points in alignment to match up perfectly or is it capable of doing a best fit?
Also, is AutoCAD capable of creating a solid 3D piece from the point cloud? I would like to take all of my points and make a smooth object.
AutoCAD Civil 3D :: Set Default Point Style For Point Groups
Jun 20, 2012How to set a default point style for point groups? Whenever I import survey points, I always put them into their own point group, so I can display each day's worth of survey data differently. For some reason, the point style always defaults to a certain style (our control point symbol). I'd like it to default to Basic, so I don't have to change this every time. Is it a template drawing setting somewhere?

Its a fairly straight forward thing on his keyboard, nothing he has set up but standard in autocad.

AutoCAD Inventor :: Using ILogic To Find Sketch Point Locations
Jul 11, 2012I would like to use iLogic to find the location of the points of a line, determine if the line is approximately vertical, and apply a vertical constraint if it is vertical.
Here is the code process I envision:
1. Automatically select a straight line.
2. Find the location of its end points.
3. Compare the X-value of the end points to see if they are vertically aligned (or almost so).
4. If they are vertically aligned, apply a vertical constraint.
5. Select next line and repeat.
Is this possible with iLogic? I don't see any way of calling a line's sketch points or finding their location.
AutoCAD Civil 3D :: How To Find Primary Point Group Using VLisp
Aug 30, 2013When I use the AutoCAD List command on a Civil 3d Point, one reported datum is Primary Point Group.
I want to get at that information with vlisp, but when I vlax-dump a point, there is no mention of Primary Point Group. If that's a limitation of using vlisp, let me know, and I won't chase it.
Maybe I have to go in through the point groups collection?
