AutoCAD .NET :: Make Layer Or Entity Transparent Within Viewport?
Feb 10, 2012
how to make a layer or an entity transparent within a viewport?
I figured out the following code found in:
[URL]
It gives an error at New Autodesk.AutoCAD.Colors.Transparency(127)
Using transactie AsTransaction = DWG.TransactionManager.StartTransaction
Dim Layertable AsLayerTable = DWG.LayerTableId.GetObject(OpenMode.ForRead)
Dim VP AsViewport = transactie.GetObject(Doc.Editor.CurrentViewportObjectId, OpenMode.ForWrite)
Dim LVPO AsLayerViewportProperties
ForEach LayerID In Layertable
my viewport is set for 2d wireframe, even when i have certain layers turned off or frozen the viewable lines in the layyers that are 'on' are broken as if i was in 2D hidden. text wont show up if over a "box" entity, no matter what elevation i set it at. The results come out upon printing as well.
There must be a display setting i am unaware of to fix this. Why do certain entities override others even if the later is at an elevation above it? Someone referred to draw order before but I still do not understand how to make that work.
I have an xref in my drawing. I am trying to use a VP override to make a layer plot with a lighter lineweight. I have changed the layer to number 9 (set to plot light) in the viewport and the layer changes color. When plotting the layer does not plot with the correct lineweight. The object color on the layer is set to bylayer. Visretain is set to "1" What is wrong? Why isn't the layer plotting correctly?
i have always wanted to know how to do this so that i can make better themes for my cell phone, ill try explain it the best i can i hope someone understands me.
Here is the theme creator for my phone, well im making one for my wife actually.....
see the red circled area thats the icon that will hover over your choice of selection. As you can see the properties are 91x69 I have found the perfect picture to hover over the menus, however if i just crop the picture 91x69 there will be some bacground image left... Code:
What I want to do is make it seem as though an image is super-imposed on another. More specifically I'm trying to put someone's face on a guitar in a picture and had two layers:
1) The guitar
2) The persons face
if it's possible to make the persons face transparent enough(If at all) so it would appear on the guitar?
If I have a black background, and I make a new layer that is transparent. Then if I put a filter>nature>flame on the transparent layer, it's not as good looking, as if I put the flame directly on the black background. Why is that? Annoys me a lot, for I can't make good pictures because of this, since I can't use layers to make it more "deep looking"
I'm trying to create a transparent layer in Photoshop. I can't even find the option to make it. Whenever I make a new layer, it just comes out white. I'm using Photoshop CS3 extended.
I am trying to add an entity on a new drawing (document) with a new layer.
Following is the code snippet I have right now.
[CommandMethod("TEST")] public void Test() { Document newDoc = Application.DocumentManager.Add("acad"); Database db = newDoc.Database; DocumentLock docLock = newDoc.LockDocument(); try { using (Transaction tr = db.TransactionManager.StartTransaction()) { BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as [code]..........
PTPUtils.CreateLayer() method creates a new layer in the given DB. However, the code gives me an "eKeyNotFound" exception in the line p.Layer = newLayer.
If I remove the p.Layer line, the code works very well. But the entity only goes to the default layer "0".
Today i opened a psd file which 200 layers. Paint.net is very slow then (as all layers are flatten, pdn is missing hierarchical layers), but that is another problem.
I wanted to hide some background layers and "copy merged" a selection.
It took me 10mn to find all the backgrounds layers without this tool.
In photoshop the tool exist as a property of the "move selection" tool. Ie: you must first select the move selection tool, then select "layer" in the properties toolbar.
Any way to get that for v4 ? Will v4 be on github so we can clone and make patches ?
I have an image with several layers. The background layer is transparent. When I merge the layers, the background becomes white. Can anyone tell me what I did wrong or didn't do that prevented my background from staying transparent.
Iam just converting back to AutoCAD from microstation.
I am trying to change the colour of a layer in my viewport. Using the layer manager i can do this but i can not get the actual item to change colour. I have checked the vplayermode is 1 and searched around but no luck !!
I have a master drawing with multiple xrefed building sketches. Looking at the model space on the "master" I can see all the room identities. However, if I go to the sheets that I have created and look at the view ports. The room identities are not there. The layer is called A-Room-Iden and it is on and not frozen...
I am trying to create a named viewport in paperspace and have to off selected layer only in selected view port. I Know to do this manually, but i don't get any idea for doing this using .net.
When dragging over a Modelspace View onto a newly created sheet in the SSM, is there a way to automatically designate it to a particular layer of choice, such as the G-Anno-Nplt layer? Just looking for a way to take an extra step out of this process.
I cannot get the layer color to change in a specific viewport. The property manager shows the new color I have selected, but the color does not change in my viewport.
I'm looking to find a way to change layer properties by viewport. I know how to freeze/thaw layer by viewport but not changing their properties. I'm using VB .Net.
If you have more than one PDF overlay, you might put them on separate layers. Generally speaking in this case, the PDF extents overlap so when i plot different sheets, I would want only a single PDF to be visible.
So, my first thought was to freeze the layers of unwanted PDFs in the viewport. Except, once i did that, nothing happened. So, i guess i have to manually freeze the layer when plotting each sheet? I then can't publish the layouts as the appropriate PDF's won't be visible.
Turning on / off a shape files layer on viewport, I couldn't figure out why turning off a shape file layer in a particular viewport (attached) does turn it off in all other viewports.
I have a drawing with polylines that are set to color 6 in model space and are also set to color bylayer.
When I go to my layout and click inside my viewport and pull up layer manager and change the viewport color for that layer to color 12, only parts of the polylines change to the color 12 while other parts remain color 6.
If while I'm in the viewport I change the model color as well to color 12, then all the polylines turn to color 12.This is a problem though, because in some layouts I what that layer to be color 6, and in others I want it to be color 12, or 4 or 5 or whatever.
I could not match this situation even if I wanted to where you draw a line, and half of it is one color while the other half is another color.why the viewport color overrides are behaving like this.
I know you can set the view port type in your template for sheet setup controls...
BUT - I have a situation where we have profile xrefs of utilities, in those utility profile drawings we must <DR> in the utilities in plan view. I don't want those utilities to show in my PLAN VIEW view port... So now I simply VP freeze the profile layers in the plan view... simple and easy...
WISH - that I could set my view port types to PLAN and PROFILE, and have only PLAN layers show in PLAN and only PROFILE layers show in PROFILE.... AUTOMATICALLY....
issue I'm having in my plot files. The way our office sets up our drawings is that we have a set of base files (which is where we do all our plans and details, etc), and then those drawings get xrefed into a different files located in a "plot" folder that that has our titleblock and viewports of the xrefed base files.
The problem is that the plot files have started to NOT save any of my layer states that are associated with the base files. For example, I have a base floor plan that has demolition, construction, RCP layer states that are toggled with LMAN. But if I open the plot file for the RCP and set up the viewports so only the RCP layers are visible...the next time I open the drawing the RCP layer state is abandoned...now ALL the layers are on and I need to redo the viewport layer states...
This only happens from time to time. I have a sheet set up with multiple viewports. I double click in one viewport, type LAYER, and the layer dialog appears but my viewport has changed.
So I'm learning about the whole new world of options with using imported .shp files in CAD and I'm unable to find a way to make a .shp file invisible in a viewport. I know I'm very close to it as there are a bunch of new contexual tabs that pop up when I select the .shp objects. It just seems that the layer control for traditional CAD does not apply through the MAPWSPACE toolspace window.
