AutoCad 3D :: Measure A Light Intensity (in Lux) In A Specific Point
Apr 7, 2011
I have a 3d Drawing with very detailed light source descriptions. Is there any way I can measure a light intensity (in lux) in a specific point of my drawing?
way to quantitatively measure the level of light intensity in different conditions. I know there are light intensity gauges that measure lumens and fc's but I was wondering if there is a way to measure the brightness of an image using photoshop?
So far I have noticed that there is a way to change basically everything about an image but I haven't found anything that gives me information about the picture itself besides its size and resolution.
Does anybody know how to measure light intensity or brightness of an image?
in an animation i need to increase and decrease a light's intensity by my audio.for example a violin's sound causes this about a spot light on violin player's head.
How do you lock the pivot point of a light to the light itself? I thought just adding a Axis node would move the light and pivot point but the pivot does not move. Is there a way of parenting them together?
I need to be able to measure the square inches of a printed area in which hew will be using specialty inks. We want to get a descent cost estimate, how to measure the square inches of a specific element of a design, in Photoshop or any of the other adobe programs?
How to use the divide and measure command , and also I knew how to change the point style. But after I used the divide command to split my object into 5 parties. I can not click the point I created.
For a instance I have a 10 meters line and I used the divide command to divide it into 5 parties, and so I have 4 points. But if i want to draw some thing on the new point my mouse could not click it.

I cant do what the guy did in the video. when I move my mouse on those points I created I could not connect a line on the point like the guy did.
I'm wondering if there is a lisp possible to measure area's by pick point (as in bpoly). This little feature exists in Microstation so i was looking for something similar.
Is it also possible if this lisp can measure areas from an external reference (dwg, dxf, dgn, shp etc..)? I'm kind of new to AutoCAD in that sence.
How can I put a light or a point on the center of a rectangle or a circle,and take the elevation from another shape as shown on this picture. aaaaaaoj.jpg
I have tried with Point Filters but the point isn't on the middle and the elevation that I want This is how I did it: [URL]
My question is how do i extend lines to a specific point? I have attached a before and after image below for an example. But obviously it takes to long to do this line by line and getting the spacing correct. Is there a way to do this?
I would like to use the behaviour of  "drag and drop" into AutoCad (from a listbox in a form) at a specific point, I do not need to drop anything into AutoCad, I just need the exact point of the mouseposition converted to WCS in autocad.
the below code works, but i do not get the correct point in AutoCad.
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDownDim ed As Editor = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor '---now i drop listbox-text in autocad, DoDragDrop(ListBox1.Text, DragDropEffects.Copy)Dim pt As Point3d = ed.PointToWorld(New Point(CInt(MousePosition.X), CInt(MousePosition.Y)))'---draw circleModelspaceAdd(Teken.Cirkel(pt(0), pt(1), 100))End Sub  (Maybe it is possible to just change the mouse-cursor, but it doesn't 'lock' the selected item in the listbox, as if it was dragged into the drawing.)
I'd like to place a point at a specific "Z" level on a line. The line is not perpendicular to the x~y plane. On the attached .dwg, say @ z+.750 on one of the angled lines on the "constraints" layer.
How do I draw perpendicular from a line or object at a specific point? I know by holding shift and osnap perpendicular I can draw the line but I can not osnap to the exact point!
I've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe? or 2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?
There was an error code in downloading the update for CS6 ....U44MIP7...Also, in filter - render - lighting ...there is no HUD point, so the light point cannot be moved around the photo.
I need to move areas of an image that I have selected using the unit of points. For example, I get corrections in our copy where I need to move certain parts of the image 8 points up or over 3 points.
I can use the measurement tool to meausure the distance but then it disappears when I try to actually move the selection. The same thing happens when I try to use guides to mark the area. I wish I could just set Photoshop to "nudge" in points instead of pixels. Is there any way to make this easier? (Photoshop CS4 version 11)
In Illustrator CS5 my anchor point handles are snapping to specific angles,which I don't want. I have to turn off Smart Guides to freely adjust the handles. Â Under preferences, Smart Guides, I turned off the custom construction guides, but even this did not correct the issue. I love using Smart Guides and I thought there were just in face that 'guides' and provided no snapping. Â I also tried turning off 'snapping to point' to see if that was creating an issue, but no dice. Â I can provide my system settings in case: Â Mac OSX 10.8.4 16 GB memory Illustrator CS5 Â Wanted to ensure I was not missing a feature I couldn't find or research before trying to reset my preferences.
I am trying to find out if it is possible to start/load the animation based on a specific point in its timeline? The animation I am creating is a parallax animation based on mouse position and I am trying to load it in the middle of the animation and based on the users mouse position will play forward or backwards from that point.
In most vector based programs I am used to using a function which allows you to paste a copied item to a specific location determined by a point-click. I find this endlessly more useful than pasting to the centre of the screen, or even paste in place, as both are rarely anywhere near where I would like an object to be. I find the function of point-click paste does away with endless dragging of objects across the screen.
I am trying to setup a a system that allows me to rotate Point 1 and 2 joints to place downstream spheres into specific locations such that the distance and angles between the spheres don't change.
Everything works the way I want (so far), but Sphere04 goes the opposite direction of its IK chain.
I have tried multiple ways to have the intensity from our pointclouds show up inside Autocad 2013 with no success. I have tried multiple jobs exporting different formats from Cyclone 7.4. The file types I have tried are PTS, PTG, and PTX. All of these file read into AutoCad 2013 and create a Pointcloud. In AutoCad the pointcloud properties state that intensity values have been loaded, but when I attempt to view them the cloud stays white. I have also tried all the Shademode types in AutoCad. The intensity values from Cyclone appear between -1000 and +1000 values. The following is a list of steps I tried on multiple projects. Software Cyclone 7.4- AutoCad 2013 File types exported and imported PTS PTX PTG Shademodes Used All Standard Modes.
I am trying to animate a casino-like light board made of tens of light bulbs/leds. I thought the easiest way to do it would be creating a matrix of bulbs arranged by material ID and then design a pattern in multi sub-object materiel so I could somehow scrub through it and achieve animation effect. The material modifier allows to change ID for the whole object only and MaterialByElement shuffle ID`s in a random manner.
I am attempting to build a facsimilie enigma machine, I would like to know how best to create an effect so that when a key is pressed a corresponding letter appears to light up. Btw I am not looking for an animated image, I can take care of the transitions between on and off, I just need to create the two image states.
I am trying to provide an image to an ad company for printing. When I change the color mode from RGB to CMYK, I lose the beautiful intense blue of the sky. I have tried to get this intensity back through photo filters, curves, levels, saturation, variations, color balance, selective color, and the channel mixer to no avail. Can anyone give me some tips on this? (I freely admit that my solution will probably be found in some combination of the above!)
