    <content>Hi, 

I&#39;m searching for a way to render a 3D picture from my design without the indoor shadow from the sun.

    <content>Hello,
I made the project of my house with all rooms in darker mode, in order to use it inside home assistant so that when I light on a light, the room illuminates.

But even if I see into the project all dark rooms, when I save the photo, I get the living room clearer than the others, as if the lights are on but it&#39;s not.

Could you help me to understand why?

I&#39;d like to attach ...</content>

    <content>Hi;
Is there a way to set a polyline default for a project?
I want to use the same size, shape, arrow design, color, etc. for a polyline without having to go back each time I draw one and choose all these options many times.
I have not been able to find a way to make this a default.
Thank you!</content>

    <content>Emmanuel,

Maybe there is a small bug in the time setting of the rendering dialogue. When I click up and down, the time changes in steps of 1 hour. When I try to set a specific time, say 08:45 AM, things become difficult. 

When I delete the entire time and start typing 08:4, the cursor jumps forward and I get something like 08:4A5M. Probably it&#39;s a bug that&#39;s there before v3.0, but ...</content>

    <content>(Not possible to paste images here?)

I click &quot;Create rooms&quot; and then &quot;Enter&quot; to get the blue spot and the little popup with its coordinates. But if I now relocate the mouse cursor, the [i]focus[/i] from the coordinates box is lost. 

How do I get focus back to the coordinates box numbers so I can manually set values? I&#39;ve tried everything I can think of.

Thank you!...</content>

I&#39;m trying to render a camera view for several times per day for every month of the year in 4k format. This works fine, but I want to automate it since I don&#39;t feel like waiting for every picture to be ready.
My batch script is ready, but it seems like SH3D doesn&#39;t accept any command line inputs. Is this possible at all? If so, could anybody tell me how or provide a sample file?...</content>

I can&#39;t find a menu or anything to do this.
AI says there is a modify menu, but I don&#39;t have one.
Double-clicking opens a Modify polylines dialog but there is no item to show or delete points.
What can one do please?</content>

Is there a way to launch multiple instances of SweetHome3D? 

I am using the linux version and launching SweetHome3D-Java3D-1_5_2. 

Attempts so far to launch multiple instances, even from different source locations just shows the one currently running instance.
