offset arc

Anonymous — Sun, 18 Aug 2019 11:18:56 GMT

I wonder why is it that hard to offset an arc? I mean when you select offset from the toolbar, you can only give distance from arc's center point to offset arc. If you want to give offset distance instead of this, you should use magic wand but sometimes it takes too much time.

Here is what you have to do:
1. Issue Offset command from Pet Palette.
2. Hover your cursor over the Arc, so the Tracker shows the radius.
3. Type the Offset value, then press + so the value will be added to the radius.
4. Press ENTER to finish the operation, the radius of the Arc will be modified to the value in the Tracker, effectively offsetting the Arc by the value typed by you.

The correct terminology here is quite important as there could be two things you are trying to do.

By 'offset' do you mean stretch (adjust) or do you mean to offset with a duplicate.
And by 'toolbar' do you mean the 'radial stretch' option in the 'Pet Palette' or the 'offset' tool in the 'tool bar'.

To adjust the radius, do as Laszlo suggested.
Select the arc, choose radial stretch in the pet palette, hover over the arc and type your figure then + (i.e. 50+) to increase or figure and - (i.e. 50-) to decrease.
You will need the 'tracker' to be active to do this.

To offset with a duplicate then activate the circle tool, pick the 'offset' command in the tool box, magic wand on the arc and offset where you want to go - it will measure from the arc.
Again you will want the 'tracker' on for this.

Here is what I do (Windows), if I want to offset a copy of multiple connected segments, a polyline or polygon:
1. ALT+click the existing element (this way you will activate the element tool and get the existing element attributes)
2. activate the offset tool in the command box (or use a keyboard shortcut for that tool, which I have defined in my shortcut scheme)
3. SPACE+click on the existing element (this way you'll define the offset path) and move the cursor in the direction of the wanted offset
4. press R (my shortcut and I think the default one for relative distance) and type in the wanted distance value

The above works with all linear or polygonal elements (lines, arcs, polylines, walls, fills, slabs, ...).

If it's just one element segment I prefer a quick element copy and manual offset by moving (or streching the copy if it's an arc segment). Everything with keyboard shortcuts (copy, duplicate, (or move a copy), perpendicular to,...), which roam to every new version of archicad with my pre-defined work environment.

Probably most of long time Archicad users who know most of what Archicad has to offer, have their own way of doing things, as there is usually more than one way to achieve a specific goal. You just need to find one that works for you best.

didn't work can't understand why archicad not allow to "duplicate offset" like any other line works.
circle also line but we can not simply click ctrl and duplicate it and offset ;((.

Sorry, this was the "offset" I was talking about. The button in the control box, which I keep in an extended form.

hmm, apparently version 23 doesn't have that feature...
thanks.

Activate the "Window > Palette > Control Box" menu item to display the Control Box. This option is located there.
