Tips and Tricks / How to render with only certain Lines invisible
« Last post by Lar on September 19, 2017, 06:15:21 AM »

This may be old news but I just discovered it:
   If a transparent material is active when you draw a line and then you go to a Shade mode with Transparency enabled, the line becomes invisible.


I'm not sure if this is a bug or not but it can be used as a trick to make CERTAIN Lines invisible when rendering. This could be useful since Hidden Edge does not work on lines and if you disable 'Lines' in the 'Display' section of the Shading dialog ALL lines become invisible.

Is there a solution to purge automatically all the incompatible garbage on dwg file ?
Get the creators of the file to delete all unnecessary entities and PURGE UNUSED BLOCKS to make the file smaller, then try loading into dcad again.

Lar
"Purge Unused Blocks" is a command so just click it and all unused blocks are gone.

If the creators are unavailable then let anyone who has autocad do the purge for you. You will have to direct them as to what other unnecessary entities should be deleted. Then you should probably purge again, so if you deleted all instances of any more blocks then they will be purged as well.

AutoDesk used to provide a free DWG/DXF file viewer called DWG TrueView. I have used it to test corrupted DWG and DXF files. Sometimes I could open a file and then save it again from TrueView and then the files would open in other programs - especially DesignCAD.

AutoCRUD leaves a lot of unused garbage in files - blocks and such that aren't actually used in the drawing. This garbage accumulates with time as the drawing is modified - sometimes most of the file is garbage. The person creating the drawing has to deliberately flush unused garbage from the file.

I have worked with files up to 750 megabytes in DesignCAD. Anything over 100 megabytes is slow, and the "slowness" increases exponentially as file size grows. My work station is a 3.7 GHz 6 core i7 with 32 Gbytes of very fast RAM, and large files still load and edit slowly.

I couldn't even open that file in 123D Design (an Autocad program). I got it to load in Sketchup Pro, then exported to DXF. That removed some objects a great distance from the main layout. It still loaded slowly (in my not-the-fastest machine). It's a large file, even "optimized" like I did.

I did not open your link but the dwg file probably has lots of unnecessary stuff and especially blocks in it.

Hello,

I'm here because i have trouble while loading a big dwg and dcd file it's take too long time.
Also when i zoom/unzoom in the file the screen refresh take very long time too.

I post the file here. Can someone can open the file and tell me if there is long loading too ?
it's too big i can't attach it to the post: https://ufile.io/0seb6


thank you,

BasicCAD / Re: Macro to save file name & location
« Last post by Lar on September 12, 2017, 05:46:39 PM »

Are there any programs you know of that already do this, where such a "page footer" can be defined and activated from the print dialog???
I can code things like this in Cinema 4D, because it has dynamic macros -  macros that are always on (once enabled). So I can control one entity's properties by another remote condition. Eg, Entity A's RGB values can be dependent on Entity B's angle, so whenever I rotate B, A's color changes. So, for a text entity I can make it display the current date and time, Then I attach this text entity to a camera and scale and position it close to the camera's lens so it always display where I want it in the picture, no matter how I turn the camera.


To do something similar in dcad you would have to place Blocks of the text wherever necessary (best in paper space sheet area - ie, not in model space), then before you print you would have to run a macro that redefines that Block to the current date/time.

BTW, does anyone know a way to make the shift, ctrl, and ctrl+shift keys lock onto the x, y, and z axes consistently instead of changing with the view?
Not currently possible. I was longing for this since that feature-combo was introduced.


Best advice I can offer is you set up 3 dedicated non-ortho views, one predominantly XY, another XZ and the third YZ. This way you can move freely in each plane by working in the relative window, without having to hold any keys (but watch out... there are some gray zones where the cursor moves along 1 axis instead of 2).


I don't do this myself. What I do is orbit (Y) the view as necessary, since you can orbit in the middle of a command. Trick is to set a focal point whenever you do a major view change, which you can also do in the middle of a command (View toolbox) (but I have a macro for this so I have to do it between commands).


Lar
ps: By the way...
I like to make a little box, set three handles and snap it onto the plan, then make a line along one of it's edges and move the box out of the way.
I use this trick too...
