AutoCAD .NET :: Remove One Selection Set To Another One
Feb 29, 2012
Assuming the model space is active with a zoom extents, my question is:
I have 2 selection sets:
- ssA= The first one that contains all the entities (SelectAll).
- ssB= The second one that as been made using the SelectCrossingWindow method.
What I want is to remove the 2nd selection set from the first one: in other words, to get (ssA-ssB).
In VBA, I remember we had a Remove Items method, but it seems not in VB.NET. How to make this subtraction?
I repeat that ssB contains SelectedObjectByWindow...

I've created a lisp that draws the boltholes of a pipe flanges, using the correct number of holes, at the correct diameter at the correct bolt-hole diameter and then rotates. Everything works seamlessly, when i do just one flange. But I've discovered that fewuently there will be mulitple times when a user will have to perform the command.
So the idea I had was to do the following:
Select all circles with (setq CirclesFirst (ssget "X" (list (cons 0 "CIRCLE"))))
Go through the code to create the new circles.
Select all circles with (setq Circles (ssget "X" (list (cons 0 "CIRCLE"))))
Remove selection set "CirclesFirst" from "Circles".
But what for some reason (command "_.select" Circles "R" CirclesFirst "") does not work.

I have been using autocad for a while and have always been able to use "R" to remove objects from a selection set. All of a sudden now when I want to use that command it activates the "Redraw" command instead of letting me remove objects from my set.
How to get it back to the way I had it before?

How can I remove an object I just selected from a selection set? I can't find the setting that allows this. Is it some combination of items check under the selection modes in the options menu?

I presently have code that will select objects on screen based on particular stored object handles. The code then prompts the user to add additional selections once these handle selections are made. No problem. The problem lies with attempting to deselect the objects that were selected via object handles. I should say highlighted because that is what the present code is doing. It is highlighting the objects on screen. The code I am using follows:
Dim ids(1) As ObjectId ids(0) = ObjectIdFromHandle(myDocDB, "1D6") ids(1) = ObjectIdFromHandle(myDocDB, "1DE") Autodesk.AutoCAD.Internal.Utils.SelectObjects(ids) ' Get the Pickfirst selection
[Code]....

I have a drawing that is 720X596 px and I have used the rectangular tool and select - invert, cut out a 222X444 px part that I need to save as a jpeg. However, I can not figure out how to either : delete the 720X596 drawing to leave the 222X444 drawing: or, select the 222X444 drawing to save it.

I have a Unwrap UVW modifier applied to an editable poly object. I used point to point seams to create the seams I wanted. There are a few seams I would like to change, how do I remove a certain selection of the seams that I want to remove?

Just a regular photo of a person on front and people and objects on the background. I tried different techniques but can't figure out how to make selection with all smallest details intact.

When I use the Fuzzy select tool or the select by colour tool, how can I remove the selection area around the parts that I don't want selected. For example. I have red car on a white background which I want to cut and paste to a black background. I select the white background, but although it selects all the white, it also selects other small areas on the car which are a similar colour. If the threshold is lowered too much when I use these select tools then I get a very small white border around the object when I paste it on to a dark surface. So instead of selecting using the default (15) or even less, I have to ramp it up so as the selection is closer to object and does not show the white jagged line. I thought that I could use the other selection tools with the "remove from selected" option selected, but each time I place a rectangle around the selected area that I want ot deselect, it does away with the entire selection area. I just cannot get it sussed.

Is there a way of distorting a selection to remove the 'keystone' effect which has made a rectangular page into a trapezium. (Photograped at a slight angle, I want it square for OCR.)

For quite some time I've been trying to find the best way to remove a white background from images. I've checked out the sticky thread on this forum and as my image isn't of great quality and because it features quite a lot of white that won't apply.
Recently I found this tutorial which is supposed to work great (as seen in the comments). However, I think that because of a GIMP update that won't apply anymore somehow. I was hoping you guys might know what was causing it.
Everything works well until I get to step 7, where I have to select to Alpha. There it selects just the outlines, but my selection includes inner parts of the image, not just the background. And then after I invert and delete, the white that remains still has transparent parts that show up on the upper layer. So, am I doing something wrong with the Alpha to Selection, is that tutorial updated or is there a better way to remove the background from ie. a logo with just one background colour which isn't of great quality.

If I select a "New" document in CS5 I find that I am only able to paint or fill in in grey scale. This is new. In the Color options panel the grey scale slider is ticked and all other options are greyed out.
How do I remove the tick by the side of the grey scale slider and make the other options available for selection as normal. I note that if I open a previously opened document all options are available it just seems to be new blank documents.

When I select a hatch or polyline or any object with grips for that matter, and hold down shift to select multiple grips on the object or objects and then press my middle mouse button to pan or scroll it to zoom, the grips that I have selected de-select, meaning I have to set up the view so that all the grips I want to move are visible before selecting them.
This is only happening on some drawings (although it is most of them) and only when I use 2012 not 2011. Which system variable it is that has gone screwy that I need to reset? or is it something else?

I have a flexible sub-assembly in my top assembly. Sometiems I'm trying to demonstrate to others how a mechanism in the sub-assembly works using this flexibility feature. It works great, but when I move just one little part of a flexible assembly, Inventor displays the wire-mesh of the entire flexible assembly, because technically the entire assembly is selected, even though I'm only moving one part. It clutters up the screen very badly, detracting from what I'm trying to show.
Is there a way to prevent Inventor from displaying the selection lines? Either only when I'm moving a part in a flexible assembly (which would be great), or to just turn them off completely when I'm presenting like this? I know I can turn off pre-select, but that doesn't work, because once I start moving a part in the flexible assembly, the assembly is "selected" and the wire-mesh displays.

When creating a selection Command using the PromptXXXOptions and PromptXXXResult. The entities are selected on the current view, but once the selection ends the entities return to an unselected state.
Is it possible to leave them in selection mode.
I want to this, because it will be better to use Editor.SelectImplied() instead of saving the last selection object Ids.

I have been continually annoyed, when creating a vector mask-heavy document, with trying to select vector mask points by dragging a rectangle only to find that it instead selects a layer higher up which has a larger vector mask.
The only workaround is to manually select the points of my mask or to drag a rectangle from outside the canvas, meaning I have to zoom out or scroll to the edge - sometimes annoying if I am zoomed in quite far.
I know that the move tool can be set to automatically select a layer, depending on what part of the image is clicked, but why is there not an option to turn this off for vector editing?

If you look closely in the attached picture, there is a spot of light blue on the player's helmet, that looks like a mistake (think it should look like the grass behind it)...though it actually may be part of his helmet.
Regardless, I'd like to take it out. My idea was to select the blue with the quick selection tool, then bring that selection out to the grass, select the grass with that size/shape of selection, copy/paste and then bring the grass selection into the blue part so it looks like grass in what was the blue part.
The problem is I don't seem to be able to move the selection without taking the blue with it (so it's not an empty selection and therefore can't select a piece of the grass.)

I have Photoshop CS5 on a Mac OS 10.7.4 My problem is that when I am using curves or a slider, my selection does not stay in the same place. For example, I chose the number 8 on a slider, after I release my selection it will either go one number after or before my selected number. I have had this problem since I got my computer, December 2011, but it has only recently started to frustrated me because of having to use Photoshop a little more than I usually do.

how to "drop out" the background from this photo (I have loads to do which are very similar). Thus far I have tried channel selections and the calculations tool + all the normal quick selection tools and I just cant get it to work without spending hours adjusting things. The end effect I need to achieve is a perfect white background without loosing any of the detail if possible. On a side note I have also tried taking the photo on blue, green, black and white backgrounds but due to the number of colours present in the products its just not working for me.

I am trying to cut a person out of a picture with a deatiled background so I am using the quickmask selection and paint brush. I'm done selecting the person and have gone back into normal editing mode. I then inversed the selection created within quickmask to select everything but the person in the background. When I click delete, the background vanishes and the person become opaque.

If I have mad a selection with say an ellipse marque, of say 100px and now I want to fether that same selection outwards, ie to start the feather 10 px outward of the 100px selection so that the 100th px has a 100% transparency and the 110th px has a transparency of zero,thus making the new selection 110px, how could I go about doing it. With the current feathering of the selection, it feathers only in the marquee already selected, not outward, and you cannot place negative feathering px. I know that there is most likely some sort of a ration where you would expand the selection by a certain amount of px, and then apply a ratio of feathering to it to enalble it to feather outside of the 100px marquee.

Right after one makes a selection, say by using the Rectangle SelectTool, is presented with handles that allow altering the selection.
If one then selects another tool without deselecting is being deprivedof these handles while the selection remains active thus rendering himunable to alter the selection in that fashion.
Thus forming my question: is there a way to make these handles to(re-)appear on a non-freshly created selection?

The Width of Selection box in the Selection Tool Inof Bar does not seem to add in the width of any line thickness. If I make a rectangle that is 500 x 250, the box correctly reflects the size. If I change line width to 16, the box still shows 500 x 250. It is a problem upon export when the exported file does include the line widths, in this case it adds a total of 16 pix (8 each side) with a resultant export not equal to the displayed width. WordPress seems dogmatic about certain widths an exact width is useful.
I suppose I can add the labor of calculating line widths to meet exact export dimensions but I do not remember doing this in previous editions. I'm thinking there is a buried setting that I have changed. Is there such a setting to account for the discrepancy?

I know how to blend selection edges of a selection in Gimp 2.8.2, but if I have only one side of a selection that needs blending, what should I do?
Lets say that I have a grey box on a black background and only want to blend the left vertical edge into the background.

This morning, my Selection Tool (the filled-in arrow) is acting like a Direct Selection Tool (the hollow arrow), but only when I click and drag on a group. It ends up select the anchors within the group rather than the whole group itself.
I've checked my preferences, quit and relaunched Illustrator a few times, and nothing seems to fix it. The problem briefly went away a few minutes ago, but came back when I quit and relaunched for good measure.
It's happening in Illustrator CS 5.1. I have CS6, and that version works fine, but I'm waiting on some plugins to be updated for it, so I'd like to use CS 5.1. I'm also running the latest Suitcase Fusion 4.
