Snap precision ?

Vojtech Slavik — Tue, 09 May 2023 13:43:33 GMT

Hi, I have often problem with snapping when I want to have in angle wall : for example 12° than in some process is 11,98°
It's make me crazy . is there someway how to set precision for example on integer ?

I had to redo many wall and would like to avoid this again

Also when I zoom to wall i can see that i can move quite a far before a i get 0.01 different number.
It's mean that i can have two lines with 180° from one point and on the and there are totally far from itself.

Thanks a lot for any advice

First the links you are providing need access.

Yes, this is quite problematic with angles and this 0.01 degree problem I've seen quite a lot. Especially it's causing problems when you place your building on the angle - that north would be on the top always.

Good news - you can achieve precision. Just you need to follow several rules:
1. Try always to place your building, that as much walls would be located on the angle 0 and 90 degrees. It's better to rotate the North than always work with rotated building.
2. If you have rotated walls, when you draw boundary line for it, or wall itself - press 'a' on the keyboard - then you can enter exact angle.
3. Also you can rotate the view, following your rotated wall. It's a small button in the lower part of the screen, next to zoom. Called 'Set Orientation'.
4. There is built-in function, that locks your mouse 0, 90, 180 degrees (and additional angle, that you can change). Just press and hold Shift when you draw.
5. You also can use Coordinates and Control Box palettes. To show them use command in menu: Window / Palettes / Coordinates - Control Box. Control Box has special tool called 'Relative Construction Methods'. Using this tool you can draw parallel lines, lines that goes 90 degree to given line etc.

Also disable the blue help guides. In my experience they cause great trouble.

Blue guides sometimes can be very useful. I usually switch them on/off when needed.

Yes, sometimes...
I do the same. Just don't have them on all the time.

Or you can just set a long delay for the blue guides to appear and hit "Q" when needed.

Thanks guys , I'm following most of yours advice already.
I'm just looking for how can I fix snapping on integer number : for example every 1° and not get 179,99°
It's so hard and time consuming to write all the time whole number.

Sometimes is necessary to have building in angle

When you have building in angle - set accurately needed rotated views - and save it in View Map. Don't rotate it manually each time when you need it to be rotated - because this is when you will do errors in precision.

Thanks 🙂 Maybe this is right way how to do it
